INTRODUCTION

This report is based on a survey of the vegetation of

the Ozark National Scenic Riverways conducted during the period

of 27 June to 12 October, 1969. The primary objective of this

survey was to obtain as much information about the plant life

along the Jacks ~ork and Current ~ivers as funds and time

permitted. This information has been used to list and discuss

the diversity of plant communities present and, with the aid of

aerial photographs, to prepare a vegetation map of the Scenic

Riverways.

Detailed de~criptions of each area studied and summary

discussions of the types of plant communities, inc.~uding o1@

fields, found along the ~.Zcenic Rivers are contained in the bo~y

~h~o report. Areas that were found to have rare or unique

olants are " ~ ~ ~" ~"~ ~.~n~m±ied ~md recommended for special protection.

Finally, during the course of this study many problems and

questions develo~ed~., for which there are at the oresent., time,

no answer~ A~ltiona~ ~o~ is recommended in these areas.

Field Methods

Originally, the basic plan of study was to establish a

number of belt transects from stream-side to the open slope or

ridge above. However, it was soon apparent that in order to

cover as much territory as possible, it would be necessary to

modify this original plan. The method fina!]~y adopted was to

study as many stations along the river as time and. funds per-

mitted and at each station to s~nple as many sites as necessary

in order to include the different plant communities present.

Stations (See Nap I) were located along the rivers so as to

sample as many t~}es of plant communities as possible. Past

experience of the principal investigator and aerial photographs

aided in the selection of stations.

The sites studied at each station were not located at

random. Rather, they were placed in plant communities that

were obviously different either in physiognomy and/or topographic

position. The size of the site sample varied, ranging from

I00 x !O0 feet to 50 x 200 feet. The square sample plot was

adequate where the topographic relief was not great. On steep

slopes or long narrow bottom-land area, the rectangular plot

was found to be more suitab~.e. In some situations where the

topography was very irregular, plotless sampling was employed.

In such cases, at ~east 50 or more measurable trees were counted.

For each site the fo].lowing physical information was

obtained when possible: degree of slope, elevation, topographic

position, soil characteristics, particularly pH, type of rock

exposed, and estimate of canopy. All trees with a d.b.h.~ 4 inches

were counted and measured. For small trees and saplings, shrubs,

~ b~yoohytes and lichens,herbaceous s~ecies, and in some cases, _ .~..

an estimate of abundance was made according to the following

classes:

Abundance Classes

! - Very Abundant - 51 or more plant units per sitesample.

2 - Abundant - ii to ~~ ~<., plant units per site sample.

~here the topography was too rugged for accurate quantitative

sampling but the flora so diverse and interesting as to warrant

attention, quantitative sampling was not attempted and only

species lists were compiled.

It is recognized that the above sampling procedures do not

orovide the type of random information desirable for definitive

ecological studies. Ho~ever, as the objective of this study

to characterize the p~ant communities as to physiognomy and

major components, it was felt that the use of selected sites

in ~hich all trees ~ere counted would provide not only a more

complete listing of species and their relative importance at

each site, but a better record of the diversity of plant commun-

ities present.

For each site where trees ~ere tabulated and measured,

Relative Density and Percent Composition of Basal Area ~ere

calculated for each species, according to the following formulas:

Relative Density = No. of trees of Species A x I00of Species A Total number of trees sampled

~,~ Composition of = Basal Area for Soecies A x I00.Basal Area o~ Species A Total Basal Area, All Species

Voucher specimens of all plants collected ha~e been deposited

in the herbarium o~ Sout~est ~issouri State Golle~e. A selected

mounted reference set has been sent to the Ozark National Scenic

~iverways headquarters at Van Buren, Missouri, and an unmounted

selected reference set sent to the U. S. National Museum.

With regard to these collections, it should be noted that

each station was visited only once and that herbaceous species

recorded represent only those taxa present and identifiab~oe at

that time. Consequently, the record of herbaceous taxa is

incomplete and at times inaccurate. For instance, few spring

flowers were still present in early s~amer ~hile at the same

time late summer and autumn herbaceous flora was either absent

or represented by a z.o,e~, abundance class than ,~ould have been

acertained at a later date.

Site 3 includes an area along the edge of the river at

the base of a steep talus slope and bluff where there are many

large boulders that are partially submerged in the river. In

this distinctly aquatic situation three species, NBphar luteum

subsp, ozarkanum, S¢irpus americanus, and Eleocharis smallii,

all infrequent, are present. The first species is rooted~in

deep water along the edge of the river, while the latter two

species are rooted in shallow water between the larger boulders.

Site 4 is a vertical, south-facing dolomitic bluff approx-

imately 40 feet high~ Soil, when present, is thin and found

in crevices or on narrow ledges. The vegetation of this bluff

is characteristic~of such a rigorous habitat. The tree~ ~

Juniperus virginiana, although infrequent, does attain a rather

large size, partic,ularly along the upper ledges of the bluff.

The shrubs, Andrachne phy~lanthoides and Hydrangea arborescens

are abundant, particul~rly along fissure lines in the bluff.~

The herbaceoustaxa, Aquilegia canadensis and Pellaea atropur-

purea are abundant .and characteristic of a bluff habitat. A

moss, G~ymonostomum so., isabundant and forms extensive tufa

along dripways and moist crevices. For a complete listing of

taxa at this site, see Table 2.

Site 5 (20 x 50 feet) is located at the base of a bluff on

a relatively steep (ca. 40° slope) south-facing bank of alluvial,

rocky, and alkaline (pH 7.8 - 7.9) soil. Because this site is

only 5 to 20 feet above the norma~ stream level, it is undoubt-

edly subject to flooding. The dominant tree species are

Platanus occidentally, especially near the edge of the water,

Ulmus rubra, and Quercus priniodes var. acuminata. This latter

species is more common along the upper part of the slope near

the base of the bluff. Although fewer in number, trees of

Platanus occidenta!is dominate the open (ca. 50%) canopy. Although

saplings of the dominants are absent, there are saplings of

potentially dominant trees, Jike Quercus rubra, Tilia american~,

and Fraxinus smerican~, present. The commonest understory

trees are Cornus drummondii and Staphylea trifoliata. The

leading shrubs are ~ arborescens var. deamii and

Rosa setigera vat. tomentosa. The most conspicuous herbaceous

plants are Nelilotus albus, Sal~ia lyrata, and Uniola latifolia.

For a list of the remainder of the taxa present in site 5,

see Table 3.

Sites 6, 7, and 8 are located on a relatively steep and

rocky (ca. 40°) south-facing slope and ridge. Numerous boulders

of cherty dolomite and sandstone are scattered through the area.

Humus accumulation occurs on the ridge but there is little on

the slopes. At the base of the slope (site 6) the pH ranges

from 7.0 to 7.2, at mid-slope (site 8) ~.8 to 5.3, and on the

ridge (site 7) ~.7 to 5.4. The forest of th@ slope is obviously

secondary for there are numerous old and large (up to 31~ inches

in diameter) stumps present. The vegetation of these sites is

shown in Tables 4, 5, and 6.

Site 6 (i00 x I00 feet) is located in a mixed pine-hardwood

forest at the bottom of the slope. The dominant trees of this

forest, Pinu~ echinata, C__ar_~ tomentosa, ~uercus alb____~a, ~.

prinoides vat. acuminata, ~. rubra, ~. stellata~ and ~. rubra

produce a rather uneven canopy ranging from open to fairly

closed (10-60%). The herbaceous flora of this site is rich,

with Asplenium o~_~.atyneuron, Lobelia spicata, and Tephrosia

virginiana var. holosericea particularly conspicuous. On rock

ledges the ferns Cheilanthes feei and C~ystopteris fra~ilis are

common. The abundance and diversity of bryophytes and lichens

in this forest is indicative of the wide range of microhabitats

present. Grimmia alpicola, ~. ~..aevi~ata, Hedwigia ciliata,

Tortella humilis, and ~tychomitrium incurvum are especially

conspicuous on the exposed rocks, while Leucodon ~ulaceus,

Drummondia prorep.ens, and Haplo~menium triste are abundant on

many tree trunks. The understory trees, Cercis canadensis,

Amelanchier arborea, and Ulmus alatus, are abundant and

typical of dry south-facing slopes.

Site 8 (200 x I00 x 150 x I00 feet) lies approximately

midway up the slope where the relatively open canopy is

dominated by the trees Carya cordiformis and Quercus velutina.

Co-dominants include Quercus alb~, ~. rubra, ~. stellata, ~.

marilandica, Pinu.__~s echinata, and Ulmus americana. Ulmus alata,

Sassafras albid~um, Vaccinium arboreum, and Comus florida, are

the most common small tree species. Vaccinium stamineum and

Ceanothus americanum are the leading shrubs. The diverse

herbaceous flora is listed in Table 6. The mosses, Atrichum

a.n~statum, ~amp~l~um chrysophyllum, Ditrichum pallidum,

Tortella humilis, and Dicranum scoparium, are common and typical

members of a rocky, acid soil flora.

Site 7 (i00 x 150 feet) is located on a ridge at an altitude

of approximately 1100 feet. Judging from the size of the cut

stumps present, there was at one time, a well-developed hard-

wood forest located on this site. The dominant trees, composed

largely of ~ercus velutina, ~. marilandica, ~. alb____~a, and

Carya cordiformis, form a relatively open (40-60%) canopy. The

leading small tree species are Cornus florida, Amelanchier

arborea, and Sassafras albidum. The vines, Parthenocissus

quinquefoli~., Rhus radicans, and Vitis aestivalis, are parti-

cularly conspicuous. The abundance of Vaccinium vacillans is

typical for acid ridges. The sparce herbaceous vegetation is

dominated by, ~ephrosia virginiana and the fern, Pteridium

aqui.linum. Mosse~ particularly Plat~gyrium repens and Homomallium

a~natu~..~ are common on decaying limbs and stumps.

Site 9 (tree count only) is in a narrow draw along a

tributary to the Jacks Fork, where steep dolomitic bluffs, up

to 20 to 25 feet high, occur on each side, especially near its

lower end. The creek has numerous dolomitic or sandstone boulders

present in its bed. and there are several places where the c~eek

bottom is literally paved by extensive flat, smooth rocks. The

dominant trees of this site include Ace____~r saccharum, Fraxinus

americana, ~ rubr~, ~. prinoides vat. acuminata,~ilia

americana vat. ne$1ecta and Ulmus rubra. The small tree species,

Asimina triloba, is particularly conspicuous in the understory.

25.

H~dran~ea arborescens and Ribes cynosbati are present on the

rock ledges where a number of interesting herbaceous species

such as Aquilesia canadensis and the ferns, Cystopteris bul-

bifera and Adiantum pedatum, also occur. Herbaceous species

are abundant on the.moist shaded soil. Bryophytes are a

conspicuous part ofthe flora of this draw. Anomodon attenuatus and

~. rostratus are abundant on exposed rocks, while Bryoandersonia

illecebra was conspicuous on soil ledges. In the creek bed,

Fissidens Erandifrons is abundant, forming extensive mats on

flat rocks, whi!e along the edge of the creek, Sematoph211um

carolinianum is common on sandstone boulders; on soil and

rocks at the edge of the gully, Cratoneuron filicinum is abundant.

All of these mosses are typical of the moist shaded habitats

afforded by this narrow draw.

Station 2 is located about % mile downstream from Station I

and encompasses a north facing talus slope and vertical dolomitic

bluff and a steep rocky s!ope above the bluff.

Site ], is located at the base of the bluff on talus at

the edge o~ the river where many trees and shrubs are growing

among the large bou!ders. Particularly characteristic are the

tree species Asimina triloba, Carpinus caro~iniana, Fraxinus

pennsylvanica var. subinte ~"~ ¯ ger~ma, Tilia americana, and

Staphylea trifo]i~, and the shrubs Amor~ha fructicosa, Cepha]anthus

occidentalis and ~_~_~socarpus oouliforius. Herbaceous taxa are

abundant and include both aquatic immersed taxa such as Juncus

interior, Nuoh__.__a~ !uteum_, Leersia oryzoides and Justica americana

and phreatophytes like Carex luci~!, ~i_setum hsemale, var.

ubiquitous Rhus radicans, Partheocissus quinquefolia, and

Similax sp., and Aristolochia tomentosa, a rather common, but

frequently overlooked sDecies. Hydrangea arborescens is charac-

teristically present on ledges and in crevices. At the base of

the bluff where seepage is common, ferns and fern allies, such as

Selaginella apoda, Adianttun pedatum, ~splenium resilens, ~.

rhizophyllum~ Cystopteris bulbifera, Pellaea atropur., purea and

Woodsia obtusa are conspicuous. Aquile~ia canadensis is present,

particularly in crevices, while Samolus p_arviflorus, a species

more characteristic of river banks, occurs on the lower ledges

of the bluff. The )2resence of such an interesting and diverse

flora is typical of north-facing, vertical dolomitic b~uffs in

this area. For a list of the species present at site 2, see

Table 9.

Site 3 (].00 x 200 feet) is located on a north-facing slope

at the edge of the bluff some 60-100 feet above the river at an

altitude of ca. 890 to 930 feet. The slope is relatively steep,

about 45°, and numerous boulders of sandstone are present and

its soil is a light loam covered by a thin layer of leaf mold,

and acid (pH 5.5-5.6). The dominant trees ~uercus velutina and

~. alba, and the co-dominants trees Ca~y_~ tomentos~, Acer saccharum,

Fraxinus americana and N~ssa s21vatica var. caroliniana form a

closed (80-90%) canopy. Vines and shrubs are numerous with

Vaccinium sO.typical in such an acid site. A wide variety of

herbaceous taxa are present with the following species particu-

larly abundant: Anemonella thalictroides, Antennaria plantagini-

folia, Desmodium ~lutinosum and Galium circaezans var. hypomalacum.

Galium boreale var. hy~op~folium, a boreal relic species, has

been reported from this general area by Steyermark (1963). The

bryophyte flora is diverse. Thiudium recognitum, Atrichum

angustatum, Aulacomnium heterostichum and E~ium affine are common

soil species while Ptychomitrium incurvum, Sematophyllum

carolinianum, and Leucolejeunea clypeata are common on exposed

sandstone. Corticolous species present include Haplohymenium

triste, Pylaiseilla selwynii, and Cryphaea glomerata. For a

Site 4 (i00 x I00 feet) is located on the upper slope

just below the ridge. The light loam soil is acid (pH. 5.5

to 5.6) and covered by a thin layer of leaf mold. The forest

canopy is relatively open (ca. 60%) and composed largely of

Quercus velutina, ~. alba, ~. rubra, and ~. coccinea. Pinus

echinsta and Carya tomentosa are important co-dominants. Pinus

echinata undoubtedly invaded this area when it was more open and

it will probably not persist here under natural conditions.

Understory trees and shrubs characteristic of this type of forest

include Amelanchier arbores, Cornus florida, Sassafras albidum,

and Vaccinium vaci~lans. Seedlings of Nyssa s~Ivatica var.

.~caroliniana are common and may eventually share dominance with

the oaks and hickories. While the herbaceous flora is diverse,

only two species, Panicum sO. and Anemone~la thalictroides are

common at this time of year. Aristo~ochia serpentaria, a species

often overlooked because of its small size, is present. The

foliose lichen Parme!ia is abundant and covers much of the

exposed sandstone. Another lichen, the fructicose genus

Cladonia, although not abundant, is a conspicuous member of the

soil flora. The bryophytes Polytrichum ohioense, Dicranum

spurium, Haploc!adium virginiantun~, and Eurh,ynchium pulchellum

var. oraecox, form conspicuous colonies on the rocky soil.

Additional members of the flora of site ~ are listed in Table ii.

Station 3, Sites 1-2 (11 July 1969)

Nap z~ (SE~ Sect. 25, T.29N., R.5W)

Station 3 is located ~ithin Alley Spring State Park. Site I

is an extensive gravel bar area north of the river and just east

of Hwy. 106, while Site 2 is the area along Alley Spring branch.

Only genera~ collecting was conducted at these sites.

The gravel bar of Site I lies on the north side of the river.

Its elevation is uneven, ranging from stream level, ca. 655 feet,

to 660 feet. There are extensive open areas dissected by elon-

gated patches of dense shrubbyvegetation composed largely of

Salix caroliniana. A large variety of s~ecies occur on bars of

this nature. Many taxa are widely scattered, but abundant, while

others are relatively rare, at least at this time of year.

On the higher parts of this bar Gleditsia triacanthos, Juglans

nigra, Platanus occidentalis, Ulmus rubra, and Asimina triloba

are abundant and frequently form dense thickets. Many of these

trees are fairly large in size. Occasional wash-outs occur

among these thickets, and herbaceous taxa, such as Campanula

americana, Polymnia canadensis, Lysimachia ciliata, Teucrium

canadense,. Mel~otus albus, and Elymus virginicus, are abundant.

Near the edge of the Salix thickets Justica americana, Vernonia

crinita and Polanisia dodecandra are common. Numerous open areas

on the higher parts of the bar have a sandy soil that supports

abundant growth of such herbaceous species as Acalypha rhomboidea,

Crotonopsis elliptica, Saponaria officinalis, Setaria viridis, and

Torilis japonica. The vine Vitis rupestris, and the herbs Kickxia

elatine and Diodia teres are more common in open gravel areas.

The vine Rhus radicans is abundant in the thickets. For a complete

listing of species present in site l, see Table 12.

Site 2 encompasses the area adjacent to the spring branch

and the alluvial area between spring branch and the gravel bar to

the south. Most of this area is presently used as a camping site.

Several trees, for example Acer ne~undo, ~. saccharinum, A. saccharum,

Populus deltoides, Aesculus glabra, ~uercus macrocarpa, Fraxinus

americana, and Platanus occidentalis, are common in areas

immediately adjacent to the spring branch. In low areas abundant

plants include the herb and Saponarla officinalis and the

shrubs S~mphoricarpus orbicularis and Sambucus canadensis. Many

of the species present in this site are particularly common in

disturbed areas, for example the genus Planta~o. No particular

effort was made to study the aquatic taxa in the spring branch.

For such species, a study of the aquatic vegetation of Missouri

by Steyermark (1941), should be consulted. For other species

present at site 2, see Table 13.

Collections of bryophytes in 1961 and 1962 at the locality

of Site 2 indicate the following taxa may still be present:

Station 4, Site 1-4 (11-12 July, 1969)

~qaps. 5 (S\,J)4 Sect. ~.,,o~ T. 29N, R.5~.)~

Station 4 is located on a steep south-facing slope and ridge

on the north side of the Jacks Fork River, west of Hwy. I06.

Although this slope appears from a distance to be densely forested

(Figure i), the upper part is rather open, and nearly glade-like.

Surface rocks of this slope are mainly a coarse crystalline, cherty

dolomite of the Gasconade formation or a sandstone of the

Roubidoux formation.

Site 2. (I00 x I00 feet) is located along the ridge at an

altitude of approximately $~0 feet. The soil is loamy, contains

few rocks and is acid (pH ,!#.9~-.5~). The forest is composed of

.H

predominantly young trees of ~.~uercus alba and a few older trees

of ..’~. velutina and ~. rubra. The canopy is closed with 70-90

percent of sky obscured by leaves and branches. Saplings of

~,uercus alba are very abundant, and are associated with a

number of youn~ trees of Fraxinus americana and Carya tomentosa.

Although obviously secondary in nature, this stand is well on

its way to becoming a mature oak-hickory forest (Figure 2).

Understory domin,~mts include Cornus florida, :Sassafras .albidum,

Prunus serotina, and Cercis canadensis. Herbaceous taxa are

widely scattered and in ~ fe~.,~ ca,~es abundant. This is parti-

cularly true for Ca_l~um arkansanum, Panicum boscii and Podo.____-

Site ~ (150 x 50 feet) is located about mid-slope

(altitude ca. 720-~40 feet) just below a dolomitic bluff 5

to 6 feet high. The alkaline (pH 7.7-8.0) soil is a ss_ndy

loam with surface rocks abundant. The steepness of this

site, 60-70°, combined with its south exposure, create a

rather dry site. Thus, the forest is relatively open with

only 50-60% of the sky obscured by leaves and branches.

Juniperus virginiana and 9,uercus prinoides var. acuminata

are the most conspicuous members of this forest (Figure 3).

If successinal patterns common in the Ozarks for this type of

site occur here, this forest should develop into a hardwood

forest with Acer saccharum, Fraxinus sp., and perhaps ~uercus

rubra sharing dominance for seedlings of these taxa are present.

The conspicuous understory trees present, such as Asimina ~riloba,

Cercis canadensis, and Comus florida, should persist into the

climax forest. Thickets of vines are present with Smilax

tamoides var. hisoida and Rhus radicans, particularly conspicuous.

On the vertical bluff along the upper edge of this site several

bluff taxa are abundant. As in site 2, in open areas the

herbaceous flora contains n~nberous representatives of a prairie-

type species. For a complete listing of the plants of site

see Table

Station 5, Sites I-LI- (12 July, 1969)

Map 6. (Sect. 25, T. 29 N., R 5 W.)

Station 5 is located on a steep, west, southwest-facing

slope and ridge above Alley Spring branch. Bluffs of a

cherty dolomite (Gasconade Formation) are common, especially

on the lo~.~er slope. On the upper slope and ridge, sandstone

(Roubidoux Formation) and cherty dolomitic boulders are scattered

throughout the more or less rocky soil.

Site 1 (150 x 50 feet) is located above the spring branch

on a steep slope (ca. ~5°), at an elevation of 680-700 feet.

Dolomite bluffs and ledges are a prominent feature at this level

and the soil is loamy and alkaline (pH 7.5-7.6). Measurable

trees are sparce (20) resulting in an open canopy with only

40-50% of the sky obscured by leaves and branches. The most

conspicuous tree species are ~uercus prinoides var. acuminata

and Juniperus virginiana while the dominant understory plants

include the shrub, Dirca palustris; the vines Parthenocissus

quinquefolia, Rhus radicans, Smilax tamoides var. hispida; and

the small trees i~indera benzoin, Ostrya vir~iniana, and Asimina

triloba. Ntmuerous herbaceous species are oresent and include

Uvularia grandiflora, Asarum canadense, Cimicifu~a racemosa

Veratrum ~oodii, Euphorbia corollata, Viola striata, Galium

circaezans, and Desmodium glutinostm~. A number of species are

confined to the bluffs such as Aquilegia canadensis, ~splenium

rhizo~h~llum, Cheilanthes feel, and Pellaea ~tro~rpurea. For a

list of the species present at site i, see Table 18. Collections made

in the spring of 196! and 1962 in this same general area indicate

that the following species should also be present~

Vicis caroliniana

Silene virginics

approximately ~1.5° at an elevation of 720-?70 feet and had a very

rocky soil which is alkaline (pH 7.~-?.8). A glade of this type

with Juniperus virEiniana and ~prinoides var. acuminata

as dominants is considered to be a successional stage eventually

leading to an Acer saccharum-(~ercus alba association. The

presence of ~rcus rubra (often found instead of 2- alba in the

climax) and numerous saplings of Acer saccharum indicate the

possibility that this will occur. Small tree~ as well as shrubs

and vines are scattered, but abundant. The herbaceous flora is

rich and includes characteristic glade taxa like Silphium

~rebinthinace~m, Bouteloua curtioendula, LithosDermum canescens,

Oenothera missouri~ns~, Rudbeckia h_~rt___9_a, Coreop.~is alm~,

Comsndra richardsiana, Verbena canadensis and A_p_~oc~num canna-

binum. Special mention should also be made of a rare vascular

saprophyte, Hexalectris spicat__a, also located at this site.

Bryophytes are abundant, particularly on exposed rocks and tree

trunks. For s !ist of the olants present at site 2, see Table 19.

Site ~ (!00 x ~00 feet) is located about ~0 feet south and

at the same elevation as Site 2. It is a steep slope, ca. 60~,

~ith a slight drs~,~ occurring near the middle and with a very rocky

soil in the neutral] to a!kaline range (pH ?.0-7.#). Large trees

of .~,uercus a!ba_, ~. rubra, and i~inus echinats form a closed canopy

under ~hich sma~l trees and saplings of Acer saccharum, A. rubrum,

and (~uercus alba are numerous. The understory is dominated by

Cormus florida, Sassafras a__ibid_~u_m~, and Vaccinum vacillans. A

rich variety of both bryophytes and herbaceous species is present.

This site apparently includes t~.,~o types of forest communities~

and oak-pine co~nunity on the steep slopes and a 9.uercus alba-

Acer rubrum community developing in a shallow draw. For a list

of the taxa present at site ~, see Table 20.

Site # (].50-50 feet) is locate.d on a gentle slope near the

ridge at sn elevation of apioroximately 860 feet. Here the soil

is thin, covered with a layer of leaf mold, and acid (pH z~.8-

6.6). Trees vary in age and form ~ relatively closed canopy with

?0-80~ of the sky obscu~red by leaves and branches. This forest

middle to upper slope is occupied by a complex hardwood forest

that is dominated by ~,uercus rubra, ~. prinoides vat. acuminata,

Garya tomentosa and Acer saccharum. Near the ridge Pinus

echinata and Juniperus virginiana are present. In open areas

along the upper slopes Rudbeckia hirta, Houstonia ~i5ricans,

Liatrus squarrosa, Parthemium inte£rifolium, and Delphinium

exaltum are common. Along the bluff ledges Aquilegia canadensis,

Hydran~e~arbor~..scens,__As_.p_olenium rhizophyllum_, A. ruta-muraria

vat. cryptolepis, and Pellaea atropurpurea are abundant. Mosses

are also common and include such species as Anomodon .attenuatus,

!. rostratus, Hedwigia ciliata, and HomaliadelDhus sharDii. The

latter species is new for the state and in fact is known from

only two other localities in the United States, both in the

Appalachians (lwatsuki, 1958).

In the narrow draw a mesic forest is well developed con-

taining many large trees of Tilia americana, 0strya virginiana,

and Nyssa sylvatica vat. caroliniana. On the forest floor the

ferns Adiantum pedatu~ Polystichum acrostichoides, Thelyoteris

hexagonopter~, and Asplenium rhizoph211um are abundant, with

the latter species restricted to shaded dolomitic boulders.

Along the lower slope, the forest dominants include Carla

cordiformis, Platanus occidentalis, Aesculus glabra, ~uercus

prinoides vat. acuminata, Tilia americana, and Ulmus rubra.

In the dense understory’beneath are found such species as

Euon,ymus atroourpurea, Carpinus caroliniana, Cornus florida,

C. drummondi.!i, ~taphylea trifolia, Dirca palustris, and Lindera

benzoin. Commonly found on the rocky bank along the edge of

the creek are the shrub species Hamamelis vernalis, H,ypericum

spathulatum, and Comus obliqua, as well as the herbaceous

species Equisetum h2emale vat. elatum, Parnassia grandiflora,

Cyperus refractus, Hepatica acutiloba, and Selaginella apoda.

A rich variety of species is found on alluvial sandy soil in

more open areas.

In disturbed areas a number of species characteristic of

old fields are present including Helenium amarum, Phleum praten.~e,

Ruellia humilis, Verbascum thapsu~,and Cirsium altissimum.

Station 7 (19 July, 1969)

SW Z sect. 9, T. 28 N., R. 5 W.

Located just south of a high vertical bluff, station 7

covers an area of very steep (ca. 60°), east-facing wooded

slopes dissected by a slight draw. Outcrops of dolomite

(Gasconade formation) form bluffs 6-8 feet high at about mid-

slope, while at the base, talus of large angular boulders is

present. This area extends over a vertical distance of 240

(720-960) feet; therefore, because of steep topography, only

a reconnaissance of the vegetation was deemed feasible. The

species encountered, including an estimate Of their abundance,

is presented in Table 23.

The forest of the lower slope is composed largely of

Quercus prinoides vat. acuminata, Acer saccharum, and Fraxinus

quadrangulata. A well developed understory consisting of

Amelanchier arborea, Viburnum rufidulum, Bumelia lanu~inosa,

Comus florida, and Cercis canadensis is present. In open

areas, Juniperus virginiana is present, while at the very base

of the slope Sassafras albidum, Sambucus canadensis, and

Lindera benzoin are conspicuous.

Further up the slope hardwoods such as Carya tomentosa,

~uercus alb~, and ~. rubra, become increasingly more abundant

until near the summit, an oak-hickory climax forest is

encountered. The rocky, acid soil of this forest supports, in

addition to seedlings of the dominant trees, only a few species of

herbaceous plants such as Adiantum p~dstum, A~plenium platyneuron,

Polystichum acrosticho.~des, Galium concinnum, Desmodium nudiflorum,

Panicum bosci~, and Cimicifu~a racemosa.

Near mid-slope where rocky bluffs occur, Rhus radicans and

R. aromatica are particularly conspicuous. Also common on these

bluffs are the ferns Asplenium rhizoDhyl~_~_~, A. ruta-muraria vat.

cryptolepis, and the mosses Anomodon attenuatus and A. rostratus.

On the soil just below these bluffs Pedicularis canad.ensis and

the mosses Bryoandersonia ~llecebr__a, Brachythecium oxTclado~,,, and

as well as Eupatorium p_Brpureum and L,ysimachia nummularia, both

somewhat less abundant. In open talus area, Pol,ymnia canaden~is

is very abundant. Herbaceous species are abundant on the lower

wooded slopes and include Asarum canadense, _H.epatica acutiloba,

and Smilacina racemosa. In a ditch between the road and the base

of this slope, Rudbeckia laciniata and Ph,ytolacca americana form

dense thickets, while at the edge of the road in open, sandy areas,

Solanum carolinense and Teucrium canadense are conspicuous.

Station 8 (19 July, 1969)

Map 7. Sect. 4, T. 28 N., R. 5 W.

This station is located in an old field just east of Bay

Creek. It is traversed by a dry, intermittant stream bed

originating out of a valley to the north. The field has a

gentle slope (about lO°), running from north-east to south-west.

The actual date of the abandonment of this field is unknown,

although an ASCS aerial photograph (BND-2EE-194) dated Oct. 22,

1964, shows this field cultivated or used as pasture at that time.

Judging from the size and number of trees of Gleditsia triacanthos

and Ulmus americana present (Figure 5), it would appear that only

two, at the most four seasons~ have elapsed since last used.

The only sizable trees within the field are a few of Ulmus

americana along the dry stream bed, and these were apparently

present in 196~. Otherwise, the vegetation is predominantly

herbaceous (see Table 24). The dominance of Erigeron annuus and

Ambrosia bidentsta may be considered as evidence of the recent

abandonment of this field. Many of the other species present

indicate that the soil is sterile due to overgrazing or poor

cultivation. These include:Helenium amarum~--~ex acetocellaPlantago lanceolataAmbrosia bidentataVerbena striataAmaranthus hF~-9-idus

Station 9 (19 July, 1969)

Nap 9. Sect. 25, T. 29 N., R. 5 W.

Station 9, located east of the west campground of Alley

Springs State Park, consists of a single site sample, lO0 x lO0

feet, in a wooded area that is about lO feet above normal stream

level. Extensive gravel bars surround this area on the north,

west, and south. The soil is sandy and alkaline (pH 7.5 - 7.7).

The dominant trees are Acer saccharinum, ~. saccharum,

Platanus occidentalis, and Ulmus rubra. Understory trees and vines

are abundant with some very large individuals of Rhus radicans and

Parthenocissus ~uinquefo!ia present. Lindera benzoin and the

shrub, Dirca palustris, are very abundant. The herbaceous flora

is rich in species with several, for example Diodia tere~,

Cocculus ~.arolinus, and Vernonia crinita, confined to open areas

in or at the edge of the forest. Bryophytes species are few in

number, and limited to tree trunks and logs. For a list of the

species present, see Table 25.

Station i0, Sites 1-4 (20 July, 1969)

Nap i0. (Sect. 4, T. 27 N., R. 6 W.)

Station i0 consists of four sites at Jam-Up Cave, an area

of both geological and botanical interest. The latter interest

is due primarily to the presence of a number of disjunct taxa

discovered here just before the turn of the century by B. F. Bush.

Particularly notable of these disjunct taxa are Galium boreale

vat. hysoppifolia, Campanula rotundifoli___~a, Zi~adenus ela~ans,

Trautvetteria caroliniensis, and Rhytidiadelphus triquetrus.

This area is one of rugged relief, dominated by precipitous

slopes and bluffs. The bluffs are composed primarily of Gasconade

cherty dolomite, while on the ridges, Roubidoux sandstone is present

(Figure 6). At the base of the bluff a gravel bar is well devel-

oped and at the mouth of the cave, a talus slope with numerous

large angular boulders is present (Figure 7)- The bluff is

approximately 120 feet high, with numerous shaded crevices and

recesses, and dripping vertical walls at the base (Figure 8).

98.

Site i is located on the narrow, saddle-like ridge (alt.

ca. 920 feet) overlying Jam-Up Cave, and is approximately 500

feet by 40 feet. Trees are widely scattered and many open

prairie-like areas are present (Figure 9). The s0il is rocky,

acid, and interrupted by several flat exposures of sandstone

(Figure 6). The north side of this ridge drops off abruptly

to the steep bluffs below, while to the south, the ridge is

bordered by a steep drop-off of about i0 feet. At its west and

east ends, the ridge rises sharply to higher slopes. On the north

side of this ridge, vertical sandstone exposures (2-4 feet high)

capped by overhanging rocks are present (Figure 6). With regard

to the plants of thi~ location, the rich variety of trees is

dominated by Pinus echinata, Quercus prinoides var. acuminata, and

Quercus rubra. Other species of small trees are also common and

include ~inus caroliniana, Cornus drummondii, Diospyros

vir~iniana,_Junip÷rus virginiana, Ostrya virginiana, Viburnum

prunifolium~ P__t_~e_~ trifolia, Cercis canadensis, and Bumelia

lanuginosa. It should also be noted that a large number of

small oaks and hickories are present, particularly near the more

densely forested slopes to the east and west, indicating that

this area may eventually become a closed pine-hardwood forest.

Shrubs are abundant throughout the area, but particularly notable

are Hypericum spathulathum and Berberis canadensis. Herbaceous

species abound, including the disjuncts Galium boreale var.

hysoppifolia and Zygadenus elegans ~hich are abundant on steep,

rocky ~orth facing ledges. However, most herbaceous plants are

confined to the more or less open areas and include many typical

glade species such as Houstonia nigricans, ~gave virginica~

Petalostem~m2_~p~_~eum, Bouteloua curt______ipend~!a, Comandra richard-

sonia, Andropogon virginicus, Silene regalia, Liatrus squarrosa,

L. scabra, Silphium terebinthinacium~ and A__s~l__e_~_oia__~s viridiflora.

Other habitats within this site include shaded vertical sandstone

areas where the fern species Cheiianthes lanosa, Asplenium platy-

neuron, and Yellaea glabella are found. In addition, areas of

open sandstone "flats" ~,~ith thin overlying soil, also occur and

support a distinctive flora which includes Selaginella rupestris,

and ~lantago aristata. For a list o~~ the flora present in this

site, see Table 26.

Site 2 encompasses an area which includes a wooded, rocky

talus slope at the mouth of Jam-Up Cave; a 120-foot vertical,

north-facing, dolomitic bluff; several steep rocky slopes; and

a large gravel bar between the bluffs and the river. It was not

feasible to obtain accurate quantitative data because of the

precipitous nature of this area. A reconnaissance however, was

conducted and the diversity of the flora is presented in Table 27.

Of particular interest is the presence and distribution of two

additional disjuncts. One, Campanula rotundifolia, is established

in crevices on the lower bluffs and large boulders near the mouth

of the cave. The other, Trautve tteria caroliniensis, is very

abundant on ledges subject to considerable seepage and drippage.

Here it is associated with such common species as ~stopteris

bulbifera and Adiantum pedatum, as well as such rare species as

Heuchera p_v_beru]a forma g!abra and Zygadenus ~lagans (Figure i0).

On the upper part of the talus slope, the moss Rhytiadelphus

triquetrus is present and associated with Bryoandersonia illecebra,

Brachythecium oxycladon, and Climacium americanum.

The gravel bar supports a diverse flora. On the higher

parts of the bar dominant trees include Acer negundo and Pla-

tanus ocG~$~ntalis, while near the edge of the river Hamamelis

vernalis is abundant. Rhus radicans trails over low growing

vegetation as ~vell as extensively on the trees and adjacent bluffs.

In the understory a luxurious mixture of shrubs and herbs is

present, including such notable species as Urtica dioica Circaea

quadrlsu~t~ C~tot~enia canadensis, Equis~tum hyemale var.

elatum, Hydra~eE~_~ arborescens, and Aster furcatus.

of Table 28 will reveal the diverse nature of the herbaceous flora.

For a small sink-hole with such steep sides, the diversity and

number of trees and shrubs is remarkable and attests to the

protected nature this type of geological feature affords. Only

at the bottom is its flora more limited, probably due to both

lack of sufficient light and periodic flooding. Even here, the

fern Cystopteris bulbifera and several mosses are abundant.

A more concerted study of the bryophytes of the sink-hole

in 1960 revealed the following species, in addition to those

listed in Table 28, to be present:

Bartramia pomiformis

Diphyscium foliosum

Fissidens cristatus

Nnium marginatum

Radula andicola

Scapania nemorosa

Site 4 is a wooded rocky ridge southeast of Jam-Up sink-

hole, at an altitude of approximately 1030 feet. Here the terrain

is level with an acid (pH 5.5-5.7) s6il, which is poor and covered

by a heavy leaf litter. The trees present obviously represent

secondary growth. Not only are the trees rather even aged, but

many have developed as stump sprguts. The canopy is fairly closed

with 60 to 70% of the sky obscured by leaves and branches. Over

70% of the trees are oaks, with Quercus velutina by far the most~

abundant species. The vine Rhus radicans, and the small trees,

Comus florida and Sassafras albidum, are the dominant understory

species. The poor soil is sparcely populated with herbaceous

species and bryophytes. The dominance of black-oak here indicates

that this area is in an advanced stage of succession that should

eventually stabilize as an oak-hickory forest. The herbaceous

flora present is also typical of this stage in succession.

For a list of the taxa present in site 4, see Table 29.

size of trees present, this field has probably not been culti-

vated on a regular basis in 8-10 years. However, it may have

been grazed in recent years, as a number of the taxa present,

such as Rhus copallina, ~. glabra, Rubus sp. Eri~eron strigosus,

Plantago aristata, Ambrosia bidentata, and Achillea millefolium,

are indicative of overgrazing.

Trees are scattered throughout the field (Figure Ii), with

individuals of CarFa texana being the most abundant, some

attaining diameters of 4-8 inches. Although two species,

Juniperus virginiana and Sassafras albidum are also common, several

others are represented by only 2-3 individuals each, and include

such taxa as Cornus drummondii, ~uercus alba, and ~. stellata.

Shrubs are common throughout. Rhus copallina, ~. glabra,

and Rubus sp. are very abundant and occur in patches (Figure Ii and

13).

Herbaceous plants~ are represented by numerous weedy taxa.

Particularly conspicuous are Daucus carota, Achillea millefolium,

Ambrosia bidentata, and Andropogon vi~.ginicus (Figure ii).

When arboreal vegetation of this old field is compared with

that sho~..~ in aerial photographs taken in 1964 ~SCS, BND-2EE-II4)

it appears that encroachment by trees is preceding at a steady

pace. Around the perimeter of the field, large trees of several

species are common, particulary Quercus stellata, quercus rubra,

and Carya texana. Should encroachment of trees continue without

disturbance, this field will undoubtedly develop into an upland

oak-hickory retest.

For a list of the plants present in Station ii, see Table 30.

Station 12 (20 July, 1969)

Nap ii. (h~E)4. Sect. 9, T. 27 N., R. 6 W.)

Station 12 is an upland old field of approximately 2 acres,

located in a slight depression and surrounded by a mature oak-

hickory forest (Figure 14). The occurrence of Lespedeza stipu-

lacea throughout the field indicates probable recent planting

with this species. Probably no more than two growing seasons,

perhaps only one, has elapsed since last cultivated. The only

119.

woody species present, Pinus echinata, seedlings of Rhus copallina,

~. glabra, and Rubus sp. occur only at the edges of the field. The

presence of the latter shrubs and the dominance of the herbs

Ambrosia bidenta}~., Eri~ero~ stri@osus, and Andropogon virginicus

indicate misuse of this field. This is further evidenced by the

light, poor, acid (pH 5.9 to 5.5) soil.

For a list of the plants present at Station 12, see Table 31.

Station l] Sites 1-5. (21 July, 1969)

Map 12. (NW)~ Sect. 96, T. 28 N., R. 5 W.)

This station encompasses a gentle northwest-facing slope

and narro~ ridge in the vicinity of Rymers Ranch. On the lower

slope, e~osures of a cherty dolomite (Gasconade Formation) are

common. The narrow ridge is derived from the Roubidoux Formation

and the soil is rocky and e~<posures of sandstone are numerous.

Site i (i00 x i00 feet) is located i0 to 20 feet above the

river on a gentle slope (i0~) at an altitude of approximately

g80-990 feet. Undoubtedly, it does receive some flooding. The

alluvial soil is gravelly to sandy, and alkaline (pH ?.2 to 9.5).

The sky obscured ty leaves and branch~s of the dominant species

Carya cordiformis, Fraxinus sp., Tilia americana, Ulmus sp., and

~latanus occidentalis. The latter species is best established

near the river. Understory trees and shrubs, particularly Asimina

tri!oba, Cercis canadensi~, .Rhamnus caroliniana, and Symphoricarpos

orbicula.tus are abundant; and vines, such as Parthenocissus

quinquefo!ia, Rhus <tdicans, and Vitis sp., trail extensively over

the undergro:<th and u~ into the trees. Herbs are abundant and are

represented by a large w~riety of species. For a list of the

plants present in Site i, see Table 92.

Site 2 is located about 20 feet upslope from Site i at an

altitude of approximately 800 to ~20 feet, and is gently sloping

(ca. 15~). The soil is light, Covered by a thick leaf layer, and

acid (DH 5.0 to 9.}). The forest is dominated by Quercus alba,

and its canopy is closed ~..~ith about 80’}¢{ of the sky obscured by

leaves and branches. It is obviously secondary, as none of the trees

are really large. Only two, one each of Querhus alba and ~. rubra,

reach lO inches d.b.h. The understory is composed chiefly of

Lindera benzoin, Cory~us americana, Rhamnus caroliniana, Amelan-

chief arbores, and Sassafras albidum. As a result of shading

and thick leaf covering, herbs and bryophytes are sparse. The

successional pattern in this forest is obscure. Although it appears

to be developing into an oak-dominated forest, it is a bit unusual

for Quercus alba to so dominate the forest at this stage; however,

in this particular case, the oaks apparently invaded early and

quickly established themselves in the area after a disturbance.

The absence of Acer saccharum is notable. For a list of the

species present in Site 2, See Table 33.

Site 3 (200 x 200 feet) is located in an old field on a

gentle slope (15 to 20°) ranging in altitude from 8~0 to 880

feet. Small boulders of sandstone are present and the soil is

acid (pH 5.2). Trees are scattered and stump sprouts are very

common. At one time this site was probably cleared of tree

species, later abandoned, and later partially cleared for pasture.

Of the dominant trees present, Gleditsia tricanthos and Juglans

nigr~ are particularly characteristic of old fields. Stump sprouts

for all trees are relatively young and even aged and indicate

that larger trees ~..~ere cut lO to~15 years ago~ Vines are very

conspicuous and some are quite large. For example, some stems

of Vitis aestivalis were up to 3 inches in diameter. Many of the

herbaceous taxa are indicative of past overgrazing. For a list

of the species oresent in Site 3, see Table 34.

Site 4 (approximately 50 x 200 feet) is ~ocated in an oak-pine

forest on a narro~ ridge (altitude ca. i000 feet). The soil is

sandy, covered by a thick layer of fallen leaves, and acid (pN 5.0

to 6.5). Approximately 60 to 70% of the sky is obscured by the

tree canopy. This oak-pine forest is typical of narrow ridges.

The dom~.na tree species are Pinus echinata, Carya texana,

Quercus alb_a, ~. rubra, andQ. velutina. Understory shrubs are

common v~ith Vaccinium stsmineum very abundant and other species,

such as Ceanothus americana, Rhus aromatica, and Rhus glabra,

Station 14. Sites 1-4 (i August,1969)

Map 13. (NW % Sect. 34, T. 28 N., R. 6 W.)

This station is located in Texas County ca. one mile south

of Harlow Ford at the south end of a sharp bend in the river.

Its location is outside of the present Scenic Riverways boundary,

although at the time it was studied, maps then available indicated

its inclusion. At any rater this is a very interesting area and

its incorporation into this report is helpful in understanding

the full range of variation in the vegetation of the Jacks Ford,

inasmuch as it is a good example of the type of rich mixed

mesophytic forest that often develops on north-facing slopes.

The slope at this station is very steep, ca. 60 to 70°, and

rises abruptly from the edge of the river; consequently there is

practically no flood plain or river bottom developed. Midway up the

slope, dolomite bluffs i0 to 20 feet high occur. The rocky soil

of the upper slopes and ridge is acid, and contains numerous

boulders and ledges of exposed Roubidoux sandstone. The pH

pattern of this slope is typical. Along the lower slope (site i)

the soil is alkaline, pH 7.9, while toward the ridge it becomes

progressively acid, reaching a pH of 4.5. At mid, slope (site 2)

the soil is slightly acid, pH 6.6.

Because of the precipitous terrain, no attempt was made to

lay out sample areas of definite size. Rather, the vegetation

of four regions-lower slope, (site i), mid-slope (site 2), upper

135.

west slope (site 3), and upper east slope and ridge (site 4)__

were sampled by tabulating all measurable trees in each region.

For the understory vegetation, an estimate of abundance was made.

The general character of the vegetation of each of these regions

is discussed below.

Sit___~e ~, lower slope. The forest developed at the base of the

slope is dominated by t~ical river bottom species such as Platanus

occidentalis, Ulmus rubra, J__uElans n__i~_~, and Tilia americana.

The understory is composed chiefly of small trees of Acer saccharum,

Carpinus carolinian~, Lindera benzoin, and Staphylea trifolia~

although near the edge of the river, Viburnum molle occurs

infrequently. Shrubs are also common, but with a number more or

less restricted to areas among large boulders at the edge of the

river (e.g. Amo____r~oh~__~a fructicosa, ~ephalanthus occidentalis, and

Physo~arpus ~oulifo~ius ). Euonymus obovatus is an important

species trailing over the soil. Of the rich variety of herbs

present, many are confined to the river edge, for example, Boeh-

meria cylindrica, Samolus parviflorus, Asclepias incarnata,

Rudbeckia triloba, Nimulus alatus, Kickxia elatine, and Selaginella

apoda. On the shaded soil further away from the edge of the river,

other species are more common. Notable taxa found here include

Adiantum pedatum_, Asarum canadense, DryoDteris marginalia,

Botrychiumvir~inianum, ~itella d~iphylla, Arisaema atrorubens,

Smilacina racemosa, and Veratrum ~,~oodii. Upon the large boulders

within the area are found typical epilithic vascular plants such

as A~~ canadensis, Hydrangea arborescens, Cystopteris bulbi-

fera, and the bryophytes Anomodon attenuatus, A. minor, Conocephalum

conicum, and Tax$~_h~llum deplanatum. The mosses Hypnum curvifolium

and Timmia megaoolitana are abundant on shaded soil. For a list of

the species present on the lo~.~er slope, see Table ~6.

Site ~, mid-slope. The character of the mid-slope differs

considerably from the lower slope, as is shown by the change in

composition of the dominant trees. Platanus occidentalis, Ulmus

rubra, and Ju~lans ni~ra are replaced in importance by Acer sacchar~m,

Fraxinus americana, ~uercus rubr_a, and Tilia americana. However,

the character of the understory has changed little from below,

except for an a-pparent increase in abunds~ce of Staphyl~a trifolia.

A rich zariety of herbs and bryophytes are found within this area.

For a list of the species present in the mid-slope region, see

Table 37.

Site 3, upper ~.Jest slope. This site encompasses a mesophytic

forest dominated by many small trees of Acer saccharum and larger

trees of ~ercus rubra and Tilia americana. Understory associates

incl.ude Car~inus caroliniana, Cercis canadensis~ Cornus florida,

Sassafras albidum, and Vac~nium vacillan~. ~axa of herbaceous

plants are fewer than are present on the lower parts of this slope.

The lichen Cladonia and the moss Dicranu~1 scoparit~n, are very

abundant on the soil. For a list of the species present on the

upper slope, see Table 98.

Site ~, u_~ooer east slope and rid~. ~his area, different

in composition from the upper west slope, is separated from the

plant communities of the lo~ver slopes by ~O-foot bluffs. Here,

a pine-hardwood forest is ~ell developed, ~ith Pinus echinata,

~uercus alb~, rubra, and ~. velutina the dominant trees and

Vaccinium so. the dominant shrub. The herbaceous flora is poorly

developed, and this, in addition to the sterile rocky soil, indi-

cates the occurrence of repeated ground fires. Near the edge of

the bluff in open areas, Houstonia Digricans and Liatrus cylin-

dracea are the common herbs. The ferns Cheilanthes feei and

Pellaea ~labella are scattered on vertical sandstone beneath

overhan~in~ ledges, while mosses are very abundant on the open

rocky soil near the bluff ledges. Particularly notable, with

regard to the latter are the presence of the rare boreal disjtmcts

Rhytiadelohus triquetrus, R__~tidium r__u~os~, and Pleurozium

schreberi. For a list of the plants present in the east area of

the upper slope, see Table ~9.

Gasconade dolomite. Site i includes the narrow talus of large

angular rocks between the river and bluff as well as the lower

bluff itself, while site 2 is a rather large gravel bar in the

river just across from the bluff. In both sites, only a reconn-

aissance of the vegetation was conducted.

Site 1 is an unusually moist site. The rocks of the talus

and the base of the bluff are subject to considerable seepage and

dripping of water from the rocks above. Trees are not abundant.

Only one each of ~D.uercus prinoides var. acuminata, Fraxinus americana,

~,uercus rubra, and three individuals of Ulmus rubra includes most

of the measurable trees present. However, all of these trees are

more common on a broader sloping ledge above the bluff. Smaller

trees and saplings are scattered, particularly where the talus is

more extensively developed. Of these, ~taph~a trifolia is the

most abundant.

The bluffs support a number of very interesting species.

Of the woody species present, H_ff_dran~ea arborescens is the most

common, although Rhus radicans is abundant and represented by

large stems that gro~ up the sides of the bluff. At the base

of the bluff where it extends down to the river, Adiantum

capillus-veneris, and C_2~opteri~ bulbifera are very common.

In addition to the common bluff inhabitating species like

Aquilegia canadensis and Heuchera sp., three species are particularly

notable, since they ~ere heretofore known in the Jacks Fork region

only from the north-facing bluffs of Jam-Up Cave. These are

Trautvetteria caroliniensi~, Campanula rotundifolia, and Zygadenus

ele~ans. The moist conditions of this bluff, even though south

facing, is condusive to the gro~th of an abundance of herbs and

bryophytes that include a number of interesting species, such

as Parnassia ~, Diarrhena americana, Ast.er furcatus,

and the tufa-forming moss, G~mnostomum recuvirostre vat. scabrum.

Several other herbs, for example ~quisetum hyemale vat. elatum,

Scirous atrovire~, and Uniola latifolia are confined primarily

to the edge of the river. For a list of the species present at

Site i, see Table 40.

Site 2 is a large gravel bar of uneven topography ranging in

relief from 1-7 feet above the present level of the river. Near

its center, the aggrading influence of goods is apparent. Trees

are scattered throughout the bar, with Platanus occidentalis and

Salix carolinians, by far the most common. Hany of the trees are

quite large, with maximum d.b.h.’s observed in the following

species: Fraxinus ~enns~ivanica - 14"; Gleditsia triacanthos - 18";

Platanus occidemtalis - i~". Vines are numerous and include some

large individuals of Parthenocissus ~uincuefolia, Rhus ~adic~,

Smilax bona-nox, and ¥itis aestivalis. Vitis rupestris trails over

the gravel in open areas

Herbaceous species are numerous, scattered, and established

best on the hi~her open parts of the bar where the gravel has

been filled with sand. Hany of tkese plants are weedy in nature,

for example Gaura biennis, Saponaria officin~is, Helilotus alb___~a,

Phytolacca s~ericana~ Campanu!~ americana, and Verbascum thapsus,

size, located ce. ~-mile ~W of Chalk Bluff. Its elevation is

~50 feet, some 10-15 feet above the present level of the Jacks

Fork River, from which it is separated by a bottomland forest

about 250 feet wide. Jud~;ing from the scattered occurrence of

woody species, this field has probably been recently used as

Station 17 (3 August, 1969)

Map 16. (SE % Sect. 31, T. 28 N., R. 6 W.)

This station is an island gravel.bar, about ~ acre in size,

located in the Jacks Fork River at Blue Springs. Rising only

a few feet above the stream level, it undoubtedly is subject to

extensive flooding. Judging from ASCS Aerial Photo (BNF-2EE-

244), taken September I, 1964, few trees were growing on this

bar. Presently, however, at its center, trees are very

abundant, and have served to stabilize the bar. Platanus

occidentalis, Ulmus rubra, and Acer ne~undo are the dominant

overstory trees, occurring primarily on the higher central

part of the bar. Also abundantly present are the smaller woody

species Salix caroliniana and Comus drummondii, particularly

~round the edges of the bar. Growing with the dominant trees in

the more heavily wooded center of the bar are the vines Rhus

radicans and Vitis sp. Another vine, Vitis rupestris~ grows more

commonly around the edges of the woods and extends to and upon the

bare gravel of open areas (Figure i~).

By this time in the growing season, herbs are becoming

very prominent on gravel bars and those present here are

typical. ~any are confined to low areas near the river, such

as Dianthera ..americ.ana, Polanisia dodecandra, Eleocharis clava,

and Scirpus americanus. Others,like Kickxia elatine, Ipomea

~andurata, Commelina erecta, Euphorbia dentata, and C~phea

~etiolata, occur mainly in open gravel areas. Most herbs,

however, are confined to either "weed patches" at the edge of

the woods, or to the woods themselves. One very common species,

Cuscuta polygon~__um is a yellowish to orange, delicate vine that

is a plant parasite, in places, its growth completely covers

the host plants.

For a list of the plants present at this station, see

Station 18, Sites 1-5. (3 August, 1969)

Map 17. (SW ~ Sect. 32, T. 28 N., R. 6 W.)

Station 18 is situated on a steep northwest-facing, rocky

slope above the Jacks Fork river about ~ mile south of Blue

Springs. Surface rocks are numerous and composed of cherty

dolomite of the Gasconade Formation.

Site i (200 x 50 feet), just below a gravel road near the

summit of a narrow ridge, is on a steep slope (ca. 45-60°) at

an altitude that ranges from approximately 960 to 990 feet.

The soil is covered by a relatively thick humus layer, and is

acid (pH 5.9).~ Here a community has become established

dominated by ~inus echinata and.the co-dominants ~uercus velutina

and ~uercns alba. Saplings of these trees plus those of Acer

rubrum, Nyssa sylvatica vat. caroliniana and Carla sp. are also

abundant. The dominant understory shrubs are Ceanothus americanus

and Vaccinium vacillans. Herbaceous ground cover is sparce,

consisting mainly of Antennaria plantaginifolia, Asplenium

platyneur0n, Euphorbia corollata, Galium arkansanum, Smilacina

racemosa, and Tephrosia virginiana. The mosses Dicranum

scoparium, Thelia asprella, and Leucobr~um glaucum are also

common on the soil. The lichen genus Cladonia and the mosses

Hedwigia ciliata and Grimmia pilifera are present on the exposed

dolomitic rocks. Drummondia prorepens occurs infrequently on

tree trunks, and Tortella humilis grows around tree bases and

adjacent soil. For the plants present at Site i, see Table 44.

Site 2 (150 x 50 feet) is at the mid-point of a steep

slope (ca. 60°) at an altitude of from 900-940 feet. Some

vertical exposures of dolomite are present, while a thin

humus covers a rocky, acid (pH. 5.5-6.5) soil. The canopy is

variable with 50 to 80% of the sky obscured by leaves and

branches. While this forest is now an oak-pine community,

a definite successional trend is discernable that is worth

noting. The composition of basal area for the dominant

trees is: Acer rubrum, 3.6%; Quercus alba, 37%; Pinus

echinata, 30%; and Nyssa sylvatica, vat. caroliniana, 16%,

Howe~er, the density figures for the same trees are: Acer~

rubrum, 17.0%; Pinus echinata, 8%; ~uercus alba, 38%; and

Nyssa sylvatica, vat. caroliniana, 13%. It is apparent that

in total number of trees, pine is losing ground to developing

hardwoods represented by many smaller trees and saplings.

There are no pine saplings present. Although the hardwoods

have not overtopped pine, they apparently are suppressing pine

reproduction by over-shading. With time, as the pines are

eliminated by disease, old age, or some other process, a climax

upland oak-hickory forest should emerge. The understory is

dominated by small trees of Acer rubrum, Ostrya virginiana,

Amelanchier arborea, ~uercus alb_~a, and Sassafras albidum,

along with the shrubs Ceanothus americanus, Hydrangea aborescens,

Rhus glabra, and Vaccinium vacillans. Vines such as Rhus

radicans and Vitis aestivalis area abundant. The herbaceous flora

is very sparce with only a few species having more than lO

representatives in the sample are (Figure 16). On the other

hand, bryophytes and lichens are abundant on the open soil and

dolomite exposures. For the species present at Site 2, see

Table 45.

Site 3 is located between the river and the base of steep

bluffs. While a sample plot of definite size was not attempted,

a reconnaissance was made of the area and the measurable trees

tabulated. Within this area where the soil is alluvial, sandy,

and alkaline (pH 7.7-7.9), it is not uncommon to find large

angular blocks of dolomite and talus ridges separated by "wash

outs". Judging from the debris in the upper parts of understory

trees, this area is covered bz relatively deep water during

flood stages. The tree canopy is open with only 40-60% of the sky

obscured by leaves and branches. A large variety of trees are

present even though their density is low. ~uercus prinoides vat.

acuminata, ~. rubra, Fraxinus sop. (2 species), and Ulmus

rubra are the dominants. The understory is dense and composed

of small trees such as Asimina triloba, Cornus drummondii,

Dio~pr0s virginiana, and Carpinus carolinana. In addition, the

shrub Dirca palustris and the vine Rhus radicans are both very

abundant, the latterespecially so along the base of the bluff.

Amorpha fructicosa and Phyto carpus opulifolius, confined mainly

to large boulders, are near the edge of the river bottom. The

herbaceous flora is diverse as might be expected in an area where

habitats range from bluffs and rocky ledges, to alluvial and

rocky, shaded soils. ~,~ile some species are more or less confined

to the alluvial soil near the edge of the river (e.g. Uniola

latifolia, Leersia yirginica), others are restricted to shaded,

rocky soil at the base of the slope. Species in this latter

~roup include Gillenia stipulata, Pol,Tmnia canadensis, Prunella

v~l~aris, Pedicularis canadensis~ Senecio aureus, Geranium

maculatum, Hepatica nobilis var. acuta and Polystichum acrosti-

Houstonia nigricans are common. For the list of species present

they represent 81.6% of the composition of basal area and

have a relative density of 93%. Carya texana and a single

large (d.b.h.=15 in.) tree of Pinus echinata make up the rest of

the dominant trees. Understory shrubs and herbs are sparce

probably due to the effect of shade and dense leaf litter.

For a list of the species present at this station, see

Table 47.

Station 20, Sites 1-4. (13 September, 1969)

Map 19. (NE % Sect. 27, T. ~i2 N., R 7 W.)

Station 20 is located on a rich north-facing slope along

the spring branch of Nontauk Springs in Nontauk State park.

Although this area is not within the Scenic Riverways, it was

chosen for study because of its representative nature and its

accessibility.

This slope rises rather abruptly from the edge of the spring

branch and is quite rocky due to the exposure of many fairly large

boulders of cherty dolomite (Gasconade Formation). The rise of

this slope is steep (ca. 45~) for the first 200 feet of altitude.

Above this point it gradually levels off, finally reaching an

altitude of about 290 feet above the spring branch.

Site i (50 x iO0 feet) extends along the edge of the spring

branch where the soil is sandy, circumneutral (pH 6.8-7.3),

and interrupted by numerous large boulders of dolomite. The

tree canopy, composed primarily of Quercus rubra, is open, with

40 to 50% of the sky obscured by leaves and branches. Other

tree associates include Fraxinus americana, Quercus prinoides

vat. acuminat~., and Tilia americana vat. americana. Saplings of

Acer saccharum, and the small tree species, Comus florida and

Lindera benzoin, are the leading understory associates. The

most common understory shrubs and vines are Euonymus obovatus,

Hydrangea arborescens, Parthenocissus ~uinquefolia, and Rhus

radicans. The herbaceous flora is rich with many of the

species confined to the wet, open areas near the edge of the

spring branch, for example, ~quisetum arvense, Veronica comosa,

Leersia oryzoides. Other species, such as Solidago flexicaulis,

Aster sagittifp~ius, Adiantum pedatum, and Eupatorium ru~osum,

are more common in shaded areas some distance above the spring

branch. Most of the bryophytes are abundant on the shaded soil,

rocks, and trees, with one species, Trichocolea tomentella, abun-

dant on soil among the herbaceous plants and rocks at the edge

of the branch. For a list of the species present in Site i, see

Table 48.

Site 2 (150 x I00 x i00 x I00 feet) is situated near the

upper part of the lower steep slope, about I00 feet above the

spring branch. The soil is very rocky, interrupted by numerous

large boulders, covered with a moderately thick layer of leaf

mold, and acid (pH 5.3-5.5). The tree canopy is relatively

closed with 60 to 70% of the sky obscured by leaves and branches.

Although Quercus rubra is still the dominant tree, as in site i,

other measurable trees include ~uercu__~s v.elu~ina, Tilia americana,

and Ulmus rubra. The understory is dense and composed of Asimina

triloba, Caroinus carpliniana, Cercis canadensis, Lindera benzoin,

Ostrya virginiana, Staphylea trifolia, and numerous saplings of

Acer saccharum. While the herbaceous flora is not as diverse as

that of the lower part of the slope, the shaded rocky soil is

conducive to a ittxuriant growth of the ferns Adiantum pedatum and

Folystichum acrostichoide~, and the mosses Anomodon attenuatus,

Bryoandersonia illecebra, Anomodon rostratus, Fissidens cristatus,

and Thuidium delicatulum. Of special interest is the occurrence

in this site of the uncommon terrestrial orchid, Orchis specta-

bilis. For a list of the species present in Site 2, see Table 49.

Site 3 (i00 x I00 feet) is situated near the summit of the

hill where the slope is gentle (ca. 20-30~) and the acid (pH 5.~-

5.7), rocky soil is covered by a moderately heavy leaf mold. The

canopy is relatively closed with 60-70% of the sky obscured by

leaves and branches of the dominant trees ~uercus alb____~a, ~. rubra,

and Pinus echinata. The understory of woody species is diverse and

includes not only ntunerous saplings of the dominants (except pine),

but also such smaller trees as Amelanchier arborea, Comus florida,

Euonymus atropur~ureus, Juniperus vir~ini~na, Lindera benzoin,

Ulmus alata, and Sassafras albidum. ~ile the vine Parthenocissus

quinauefolia is abundant, another, Rhus radicans, is conspicuous

by its absence. Although the herbaceous flora is sparce, it does

contain several notable taxa, such as the terrestrial orchids

C,ypripedium calceolus and Orchis spectabilis, as well as the

saprophyte ~onotropa uniflora. The bryophytes present are

characteristic of wooded uplands with acid soil. Special mention

should be made of an unusually large tree of ~iosp.yros virginiang,

d.b.h. 22% inches, located just outside the site sample area. For

a list of the species present in Site 3, see Table 50.

Site 4 is located on the ridge (elevation 1160 feet), where

few surface exposures of dolomite are present and the soil is poor

and acid (pH 6.0). Although measurable tree species are present,

they are generally young and infrequent; however, saplings are

abundant, particularly the species Acer saccharum, Carya

tomen~osa, Pinus e~hinata, and Quercus alba. Judging from the

diversity of the woody flora of this site, it appears to be an

area that was clear-cut and used for grazing until recently.

Furthermore, the abundance of the grass, Dant~onia spicata,

suggests the possibility of frequent burning. The openness

(canopy ~0-60~) of this site has permitted the growth of a large

number of herbs including a number of characteristic prairie

to approximately 250 feet above the Current. River. The soil is

rocky throughout, and exposures of a cherty dolomite (Gasconade

Formation) are common.

Site i (i00 x i00 feet) is located on the ridge at an

altitude of ca. llO0 feet. The soil is very rocky, covered

by a thin layer of leaves, and acid (pH 5.0-5.3). The forest

present here is representative of one of the more common varia-

tions of the oak-pine association in the Ozarks. Dominance is

shared by Quercus alba, ~. stellata, ~. velutina, Carya tomentosa,

C. texana, and Pinus echinata. Together, they form a fairly closed

canopy with 60 to. 80% of the sky obscured by leaves and limbs.

Saplings and seedlings of the oaks (except ~uercus stellata and

~. marilandica) and hickories are abundant, but no pine saplings

or seedlings are present. Therefore, if pine fails to reproduce

itself and if the forest is left undisturbed, it will probably

become a typical oak-hickory association. Although considered

intolerant to shade, the occurrence of a few saplings of Quercus

stellata and ~. marilandica is probably a consequence of an

incompletely closed canopy. The relatively few herbs and

bryophytes present is typical of forest sites such as this one.

For a list of the species present, see Table 52.

Site 2 (lO0 x 100 feet) is situated in a hardwood-pine

forest on the upper slope from approximately 1040 to 1080 feet.

The soil is rocky and acid (pH 4.2). Sixty to seventy percent

of the sky is obscured by the crowns of the dominant trees,

Carya tomentosa, Pinus echinata, Quercus alba, and Q. velutina.

The understory is composed chiefly of small trees of Amelanchier

arborea, Comus ~lorida, Sassafras albidum, and Vaccinium

arboreum. Both the vine Parthenocissus quinquefolia and the

shrub Rhus aromatica are abundant. Judging from the presence

of small saplings of the dominant trees, it appears that this

forest has reached a climax, consisting of an oak-pine association

(sensu Steyermark, 1940). The sparcity of herbs and bryophytes is

typical of acid forest sites like this one. For a list of the

species present, see Table 53.

Site 5 (i00 x I00 feet) is located near the base of the

slope and its lo~Jer boundary is about 20 to 25 feet above the

river. The soil is neutral (pH 7.0) and the forest canopy

composed largely of Juniperus vir~iniana, Pinus echinata,

~uercus prinoides var. acuminata_, and ~. rubra, obscures only

about 40 to 60~:~ of the sky. Though not forming a significant

part of the canopy at this time, the presence of a few small

trees of Acer ssccharum, ~uercus alba, Carla sDp. and Fraxinus

spp. is suggestive of a successional trend that should eventually

produce an ecotonal-type forest that often exists between an

upland sugar maple-white oak association and a bottom land

sugar maple-bitternut hickory association. Understory trees

are common and include Celti.s tenuifolia, Comus florida~

Frunus ceratu~, Rhm~nus carolinians, and Vaccini~ arbores.

The vines Camosis radicans, Parthenocissus ~uinquefolia, ~d

ammlax bona-nox are abundant In ooen areas the herbaceous

flora is represented by many species that are characteristic

of glades, for example, Aster lina.riifoli~, Coreopsis palmata,

Houstonia ~an~, Rudbeckia birth, Ascleoias verticillata,

Site 5, see Table 5~4.

Station 22 (15 September, 1969)

Hap 21. (Sect. 56, T. 2~ N., 19. 7 W.)

Station 22 is located on the north bank of the Current

River at a point where it turns abruptly to the east and back

to the north, thus partially enclosing a U-shaped land area.

Because this ares is io~ (only)~ to 2 feet above the river),

it is subject to the aggrading influences of frequent flooding.

Near the edge of the river, just before it turns abruptly, a

low, wet gravel bar is present.

The iro~riant flora is predominantly herbaceous and weedy

in nature. The only woody species present are the small trees

Sambucus canadensis and Salix niE=r_a.. }~ost of the taxa are more

abundant on the drier sandy areas, although a few are restricted

or best developed on the low, wet ~ravel bar. Species in this

latter category include Veronica £o_~os~a, C~erus strigosus,

Eupatorium perfoliattun, Leonurus cardiaca, Perilla frutescens ~

Artemisia annua, Bidens discoi~ea, P~olygonum hydropiper, Bidens

cernua vat. cernua, and ~. polylep~ var. Dolylepis. For a list

of the diverse flora at this station, see Table 55.

Station 23 (13 September, 1969)

Nap 21. (Sect. ~6, T. 2} N., R. 9

Station 2} encompasses a small north-facing, dolomitic

bluff (10-12 feet high) and steep (ca. 45~), rocky slope just

across the river from Station 22. The soil is rocky and,

judging from data at other similar sites, probably acid (no

sample taken). A samDle area of definite size was not estab-

lished, but rather a reconnaissance of the bluff and steep lower

slope was conducted and all measurable trees tabulated. While

there are quite a ntumber of different tree species present, the

canopy is rel~tively open (about 60~ of the sky obscured byleaves and branches), and largely dominated by Acer saccharum,

Quercus spp., Fraxinus ~sp_~_., and Tilia americana. The under-

story is composed chiefly of saplings of the crown dominants

and smaller trees such as Cornus florida, Juniperus virginiana,

Lindera benzoin, Ostrya virginiana, Staphylea trifolia, and

Viburnum prunifolium. Shrubs like H_~_d~.r__ange___~a arborescens and

vines such as ~uonymus obovatus, Hhus radicans, and Partheno-

cissus quinquefolia are common understory associates. A diverse

herbaceous flora exists here because of the range of habitats

present, such as rocky areas along the base of the bluff and

at the edge of the river, vertical bluffs with rock ledges, and

areas of rocky shaded soil. ~ " opec~es common on the bluffs and

rocks near the river include the herbs Lycopus rubellus var.

arkansanus, Bidens connata, Boehmeria cylindrica, Leersia

virginica, Prunella ~ulgaris, and the bryophytes Anomodon

attenuatus and Conocephalum conicum. On the vertical bluff

and rock ledges, the herbaceous species Asplenium rhizophyllum,

Aquilegia canadensis, Pellaea atropurpurea, and Cystopteris

bulbifera are abundant. The bryophytes Gymnostomum aeruginosum,

Anomodon rost~atus, Cololejeunea biddlecomia__e, Radula andiooSa,

and Br_~y_hnia Eraminicolor are also common in the bluff area. Taxa

abundant on the rocky soil of the lower slope include the her-

baceous species Adiant~n pedatum_, Anemone vir~iniana, Aster

Station, see Table 56.

Just west of this station is a river-bottom forest,

surrounding a small pond, where the rare floating aquatic,

Spi~.o~el__ap_0~hi_~z~~ is abundant. In the wet area around this

pond, the herbs Elephantopsis caroliniana, Impatiens capensis,

Ei.7-mus virg.inicus, and Lobelia si___~obilitica form a dense under-

growth upon which the parasitic plant, Cuscuta compacta, is

profusely ~rowing.

Station 24, Sites 1-5 (l~ September, 1969)

~ect. ~i, , .Hap 22. (S~ ~4 ~ T. 52 N. R 6 ~.)

Station 24 includes a variety of habitats and includes

an old gravelbar-river bottom area (site 5); a pine-hardwood

forest in a relatively low (for pine) area (site ~); a steep

south-east-facing, rocky glade (sites I and 2); and oak-pine

ridge (site 3). The rocks e~posed at this station are predomi-

nantly a cherty dolomite of the Gasconade formation.

The lower boundary of site i (i00 x i00 feet), at an

altitude of 900 feet, e~tends along the upper edge of a steep bluff

that rises about ~0 feet above the river bottom. The upper boun-

dary of this site is some 80 feet higher indicating a rather

steep slope, ca. 50°. The heavily eroded soil is thin, very

rocky, and alkaline (ph ~.5-~.~). Here, trees are widely

scattered, (canopy lO~) resulting in what is known as a "cedar

~lade", because of the conspicuous presence of red cedar,

Juniperus vir~iniana. The hardwood species, ~uercus prinoides var.

are common tree species associates v~ich have invaded this glade

and which should eventually result in the establishment of a

sugar maple-white oak climax (sensu Steyermark, 1940), Shrubs

and vines are abundant, and the abundance of H~r.angea arbore-

sc.en.s, Rhus aromatica, and Smilax bona-nox are considered

characteristic of "cedar glade" associations. The herbaceous

flora is diverse at this time of year, and includes a large

component of prairie species such as Andropo.gon 5erardi, ~.

scooarius, Bouteloua curtipendula, Rudbeckia hirta, Silphium tere~-

binthinaceum, Liatris ~, Physostegia virsiniana, and Aster

ptarmicoides. Surface rocks are frequently covered by growth of

the moss Grimmia aoocarpa. On tree trunks other mosses, par-

ticularly Drummondia ororepens and Leucodon julaceus, are abundant.

For species in this site i, see Table 57.

Site 2 (i00 x i00 feet) is situated about midway up the

slope from an altitude of approximately 1020 to 1080 feet.

The angle is still steep (about 50°), and the soil at this level

is eroded, thin, rocky, and acid (pH 5.9-6.0). As in site i,

trees are widely scattered (canopy 10%), but Juniperus virginiana

is of less importance here. Hard~oods characteristic of acid,

upland forest sites like ~uercus rubra, ~. stellata, and ~

texana are present, along with Quercus prinoides vat. acuminata,

a species more characteristic of alkaline sites. Small trees

are abundant, particularly the species Cercis canadensis,

Diosoyros virginiana, Ulmus alata, and Viburnum rufidulum. As

in site i, the shrub Rhus aromatica and the vine Smilax bona-nox

continue to be abundant, although now here Hydrangea arborescens

is missing. The herbaceous flora is similar to that of site I,

although the relative abundance of a few taxa has changed.

For example, ~ altissimum, Houstonia nigricans are

very abundant at this site, but only abundant in site l.~C~onver-

sely Bouteloua curtipendula~ AndroD~_y~gera~di, ~phorbia

ciliata occur abundantly with Grimmia apocarPa on exposed rocks,

v~hereas in the former site only Grimmia apocarpa was abundant.

For the species present in site 2, see Table 58.

Site 3 is located on the narrow ridge at an elevation of

about ll©O feet. No specific sample size was made, but a

tree count was conducted and abundance of other plants estimated.

The soil is rocky and probably acid (pH sample lost) judging

from data obtained at similar sites. The tree canopy is

variable, ranging from ~0 to 80% of the sky obscured by leaves

and branches of a hardwood-pineforest, ar~c~mpos~d mainly of Pinus

echinata and .~uercus a!Ba. Small tree associates include

Amelanchier arborea, Cercis canadensis, Sassafras albidum, Ulmus

alata, and Cornus f__Iprid~. In addition, the shrubs Vaccinium

stamineum and Rhus copallina are abundant, with the former

found throughout the area and the latter restricted only to

open areas. Herbaceous plants and bryophytes are abundant,

particularly in open areas~ but represented by relatively few

species. For the species present in site 3, see Table 59.

Site 4 is located on a gentle slope (ca. 20°) at an alti-

tude of approximately 970 feet and is traversed by several

gullies. A site of definite size was not established, but a

tabulation of the trees and an estimate of abundance for other

plants was made. The soil is light, rocky, covered v~ith a thick

layer of pine needles and probably acid (pH sample lost). About

40 to 50% of the sky is obscured by a canopy dominated by

Pinus echinata. In fact, some of the largest pines encountered

in this survey are present here, ~ith several over 18 inches d.b.h.

Associated ~ith pine in order of importance are Quercus alba,

Platanus occidenta!is, Quercus velutina, and Nyssa sylvatica

vat. caroliniana. Saplings of the dominants (except Platanus

occidentalis), as well as Acer rubrum, C__a.r_y_~ texan~, and ~.

tomentosa are abundant. In addition, Vaccinium arboreum, Cornus

florida, and Sassafras albidum are the leading understory trees.

The herbaceous flora is sparce, no doubt due to the heavy layer

of pine needles. For a list of the species present in site 4,

see Table 60.

Site 5 includes an alluvial forest area at the base of

the bluff on a heavily ~ooded, old gravel bar.. As in site 4, no

definite site sise was established, rather, a tabulation of

measurable trees ~as made and the abundance of the other plants

estimated. The canopy ranges from open around the edges of the

gravel bar, to fairly closed near the ba~e of the bluff. The

soil is sandy on the higher Darts of the bar and at the base

of the bluff, ’but gravelly elsewhere; pH ranged from 6.4 to

7.2. The dominant trees, particularly of the bar, are Platanus

occidentalis and Betula ni~ra. Other trees such as Acer sacc-

harum, ~rsximus ~mericana, ~uercus rubra, Tilia americana, and

Ulmus rubr~, ~ere more frequent on the allu~ial soil near the

base of the bluff. The herbaceous flora is extremely diverse

and contains a nu~ber’of interesting taxa. One such taxon is

the fern, Onoclea sensibili___s_, gro~.~ing near the edge of the river

(Figure I~). Bryophyte species are rare and only one species,

Leskea ~racilescens., is conspicuous on tree trunks. ~or a list of

the species present in site ~, ~e Table 61.

Station 25 (14 September, 1969)

~lap 23. (NE)4 Sect., 23, T. 31 N., R. 6 W.)

Station 25 encompasses a co~mplex gravel bar located on the

north side of the Current River just west of Akers Ferry. Along

the edge of the river the bar is low and ~et and a small island

section has been created by a divergence of the main river

(see map 2~ and Figure 18). The remainder of the bar is higher

in elevation, uo to 2 feet above stream level, with soil that

is dry, sandy, and acid (pH 6.6 to 7.0). Near the bank side

of the bar, ~ashouts are common, exoosing dry gravel areas. The

north side of this bar is terminated by a steep, eroded bank,

5-6 feet high.

For the most part, trees are scattered, and the only species

with measurable representatives are Betula ~i~ra_~ Acer sacchari-

n__~, Dioso~ros vir~inisna, and P!atanus occidentalis. Of these,

Betula ni~a and Platanus occidentalis are the most prominent,

218.

~-~ith saplings of the latter species very abundant (Figure 19).

Typical ~ravel bar Small trees such as Hamamelis vernalis,

Salix caroliniana, Cephalanthus occidentalis, and Alnus serrulata

are abundant and tend to occur in patches on the higher parts

of the bar (Figure 20).

Herbaceous species abound at this time of year and bars

like this have been a]?tly described as "botanical trash heaps."

Ho~Jever, there does seem to be some pattern to the distribution of

many species. For example, some are more or less confined to the

lower, ~-~et areas of the bar, and include:

Station 26, Sites l-A. (20 September~ 1969)

~ap 2#. (Sect. i#, T. ~i N., R. 6 ~.)

Station 26 is located on a uniformly steep (ca. 30~) west

facing slope of a narrow saddle ridge just north of Akers Ferry.

The soil throughout this slope is heavily eroded, thi~, very

rocky, and alkaline (pH ~.2-~.6). Surface exoosures, bluffs

(5-6 feet high), and ledges of a hard dolomite (Eminence Formation)

are common. Even though this slope extends to nearly 230 feet

above the Current River, the forest is remarkably uniform from

near the base to the summit and it appears to be developing

into one of the drier variations of a sugar maple-white oak

climax (sensu Steyermark, 1940) that is characterized by the abun-

dance of ~uercus prinoides var. acuminata.

Site I (150 x 50 feet) extends from about 920 to 950 feet

or almost to the summit of the slope. The area is covered with

a large number of small trees and a dense understory of shrubs and

vines. Though the number of trees is large, the canopy is

relatively open with only about 50~$ of the sky obscured by the

leaves and branches. $umiperus virginiana and ~uercus prinoides

vat. acuminata, are the dominant trees, occurring with other

tree associates such as Acer saccharum, Fraxinus americana, ~rcus

rubra, Ulmus rubr~, and Tilia americana. These latter trees are

characteristic of a successional stage which may eventually become

225 ¯

a mesic sugar maple-white oak climax. A rich variety of under-

story trees is present that includes Celtis tenuifolia, Cercis

canadensis, Cornus ~ond~i, Diosp~ros virginiana, Ostry~

virginiaDa, Ptelea trifoliata, and Rhamnus caroliniana, many

which were probably important constituents of an earlier success-

ional stage. Shrubs and vines are very common, particularly the

vine Smilax bona-nox and the shrub Rhus aromatica. Herbaceous

species are conspicuous at this time of the year, particularly

members of the Compositae like, Coreo~is palmata, Eupatorium

ru__~@~_~_,_!]_u~.b_eckia hirt____~a, and ~lida~o spp. Others, such as

Pella__e__a ~opurp~e_~a, ~. l~lla__, Asplenium ruta-muraria vat.

crytolepis, Heuchera americanum var. hirsuticaulis, Solidago

dr.ummond~i, and S. buckleyi are more or less restricted to the

small dolomitic bluffs and ledges. Bryophytes are also conspi-

cuous, particularly on the exposed rocks and trunks of trees.

For a list of the species present in site I, see ~able 63.

Site 2 (150 x 50 feet) extends over a vertical distance of

approximately 50 feet (850-500 feet). Like the forest in site i,

trees in this lower site are small and scattered and the canopy

is open with only about 50~ of the sky obscured by leaves and

branches. Although the trees present in this site are the same

as in site i above, the relative importance of some species is

significantly different. Here hardwoods characteristic of a

mesic climax forest, particularly Acer saccharum, [[uercus rubra

and Fra~inus americana, are greater in number and size. Further-

more, Carya app. appear to be invading the site. Understory

trees are common, with St__~h~lea trifolia the most abundant species.

Shrubs and vines form a dense understory thet is, because of two

species of Smilax, almost impenetrable. The herbaceous and

bryophytic floras are so diverse that no attempt will be made here

to describe them. Hov~ever, for a list of these taxa, as well as

the woody species present in site 2, see Table 64.

Site 3 (i00 x 50 feet) is situated at the base of the slope

just above a small bluff that rises 10-15 feet above the river.

The area included in this site rises a vertical distance of

nearly ~O feet (790-8~0 feet), and its floristic composition is

similar to the sites above. The dominant trees continue to be

226.

of the slope, ~.Alere only an estimate of abundance of the species

present was made. ~dost of the taxa present are considered

characteristic of bottomland forests or stream banks. The only

exceptions are the fern Cystopteris bulbifera and the moss

G,ymnostomum recurvirostre that occur on the vertical bluffs at

the edge of the river. For a list of the plants present in

site 4, see Table 66.

Station 27 (20 September, 1969)

~qap 24 (Sect. i~, T. ~I N., R. 6 ~J.)

Station 2~ is a small field (ca. ~.~ acre) ~-4 feet above

the normal stream level that is located between the river and

a vertical dolomitic bluff. The soil is alluvial, sandy, and

neutral (pH ~.~).

Except for a number of small trees of Asimina triloba near

the base of the bluff and a fet~ scattered individuals of Gledit-

sia triacanthos, Juniperus vir~$_niana, and S,ymphoricarpOs

orbicularis, t,~oody perennials are not common. However, grasses

such as Panicum boscii, ~_ vir~ini~u__~s, Leersia or~zoides,

~. vi~i~, and ~’~uhlen~.~i_~ischreberi are common, particularly

the latter three species which are abundant along the edge of the

field nearest the river. Other species of herbaceous plants are

also conspicuous at this time of year, notably Pilea pumila

Agastache nepetoides, Daucus carota, Rudbeckia triloba, Po!ygonum

Station 28, Sites 1-4. (20 September, 1969)

Nap 23. (Sect. I#, T. 31N., R. 6 W.)

Station 28 is located on the south side of the Current

River just ~,~est of Akers Ferry where north facing dolomitic

(Eminence Formation) bluffs and ledges and a steep wooded rocky

slope are present.

Site i (reconnaissance only) includes the bluff and narrow

talus slope and ledges along the edge of the river. On the talus

slope small trees are numerous, particularly the species Asimina

triloba, Lindera be___n~oi__D_n, and Carpinus caroliniana. Although not

abundant, several large trees of ~latanus occidentalis grow

angled out over the river. On the trunk of one of these trees

the fern Polffoodium ~d~oides var. michatuxianum and the moss

Hynnum. curvifo!ium are abundant. A number of herbaceous plants

are restricted to the talus slope area and include Pilea ~,

Adiantum p_~atum, Aster lateriflorus, Perilla frutescens, Scutell-

aria late~.~lora, Arisaema trin~lum, Cassia marilandica,

C~vno~lossu~.. virginianum, Geum canadense, Rudbeckia laciniata, and

Thaspium barbinode. The dolomitic bluffs rise abruptly from the

river to a height of lO-l~ feet, have a few narrow ledges, and

are moist as the result of seepage. The conspicuous components

of the bluff flora include the shrub H~_a_n~ arborescens and

the herbaceous plants Heuchera pub~rula f. puberula, Adiantum

capillus-veneris, Cystooteris bulbi£era, Aqu~legia canadensis and

As~lenium Dl~e~ro___D_n. On the moist ledges H~strix patul~,

Lobelia siphilitic~, Oxalis so., Sela~inella apoda, Sedum sp.,

Thal~ctrum dioicum and ~olz~mnia canadensis are common. A

number of herbaceous species are commonly restricted to the soil

and boulders in or at the edge of the river. These are Leersia

vir~inica, L. oryzoides, L_2lcoous rubellus, Bidens connata,

~uhlenber~ so., and A_~rg~tis j~erennans. Epilithic mosses and

liverworts are common, particularly along the moist bluff, while

the aquatic species Brac~thecium rivulare, ~orell__a pinnata,

Fontinalis filiformis and ~issidens ~randifrons are present on

submerged rocks at the edge of the river. For a list of the plants

present in site i, see Table 68.

Site ~ (reconnaissance only) includes a relatively open

area (ca.)~ acre) near the ridge a~ian elevation o£ 990-1000

feet. Trees are scattered and judging from the number o£ fresh

cut stumps present, this area has been recently cut. The soil

is heavily eroded, rocky, and slightly alkaline (pH 7.2). Carya

tomentosa and ~uercus ve!utina are ~the most common trees still

standing, some of which are fairly large (up to !0 inches d.b.h).

Saplings of Pinus echinata, Quercus alba and Q. rubra are scattered

throughout the site, while the shrubs, Ceanothus americanus and

VacciniuJa sp., are abundant. In spite of the open nature of this

site, the number of herbaceous species is remarkably low. However,

this may be explained by the occurrence of a closed forest on this

area unit recently. For a list of the species present in site 4,

see Table 71.

Station 29 (20 September, 1969)

Hap 2}. (Sect. 14, T. 31N., R. 6

Station 29 (tree count only) is a low alluvial forest of

about ~ acres on the south side o£ the Current River just west

of ~ers Ferry. As this forest lies only }-~ feet above the river,

flooding is undoubtedly a common occurrence. The soil is sandy

and slightly acid (pH 6.8).

The canopy is relatively closed’with 60-80% of the sky

obscured by the cro}.~m dominants Acer saccharum, Celtis occiden-

talis, Praxinus americanus, Platanus occidentalis and quercus

macrocarpa. The understory is composed chiefly of Asimina

triloba, Lindera benzoin and saplings of Tilia americana. Near

the river young trees of P!atanus occidentalis are abundant.

A luxuriant undergrowth of herbaceous plants is present and

the dominant species are Ambrosia artemisiifolia, Leersia

virginica, Polygonum scandens, Vesb6sina helianthoides, Bidens

bipinnata, Cynoglossum virginianum, Impatiens biflora, Polygonum

punctatum, Scroph~laria marilandica’and Nuhlenbergia frondosa.

Near the base of the adjacent slope Laportea canadensis and

Station 30, Sites 1-3. (20 September, 1969)

Map 25 (SE % NW % Sect. 18, T. 28 N., R. 2 W.)

Station 30 is located at Rocky Creek Falls Shut-In, an area

where erosion by a surface stream has caused the exposure of

felsite, a resistant igneous bedrock of Precambrium Ryolite.

This particular area begins as a narrow valley above a cascading

falls and opens into a wider valley below the falls. The sites

studied were restricted to rocky exposures at and surrounding the

falls and to a rocky, NW facing slope SE of the falls.

Site I (reconnaissance only) includes the extensive open

felsite exposures surrounding the £alls as well as a low area

around the pool at the base of the falls (Figure 22). Few trees

occur on the open felsite around the falls except for those

species that have become established and survive in crevices.

These include Acer rubrum, Diospyros virginiana, Ulmus alata,

Rhus copallina and Amelanchier aborea. Other tree species include

Alnus serrulata, Cephalanthus occidentalis, and Platanus occi-

dentalis which are restricted to the low area surrounding the

pool, where they are abundant. Many of the herbaceous species

growing in site i are also restricted to the low, wet habitats

in or around the pool. These are :

Site 2 (i00 x i00 feet) is located on the lower part of a

steep (ca. 30°), NW-facing, extremely rocky slope. Numerous

large angular boulders are scattered through the acid (pH 5.2-

6.4) soil where~, in fact, many are so large they form small bluffs

and ledges, The canopy is relatively open with only 40-60% of

the sky obscured by the crowns of the dominant trees ~uercus

alba, Pinus echinata, N~ s~ivatica var. caroliniana, ~uercus

rubra, and ~. velutina. Understory trees and vines are abun-

dant, especially such small tree species as Acer rubrum, Rhus

~o~allina, Vacciniumarboreum and Comus florida and such

vine species as Lonicera flava, Parthenocissus quinquefolia,

Rhus radicans and Smilax bona-nox. The herbaceous flora is

poor in number of species, although those present are numerous.

One fern species, Dryopteris mar~inal~.s., is restricted to shaded

rock ledges. For a list of taxa present in site 2, see Table 74.

Site 3 (reconnaissan~ only) is an open felsite glade near

the summit of the slope at an altitude of 880-920 feet. Flat

exposures of rock are extensive and ~vhat soil is present is

rocky and acid (pH 6.4), forming a shallow layer over the bedrock.

Consequently, the soil is easily saturated by even small

amounts of rain, but like~ise, it dries out quickly. Under

such conditions trees are widely scattered, dwarfed in their

growth, and generally located along fissure lines where soil

conditions and thus moisture conditions, are more favorable.

Only a few species occur in this situation such as Ulmus ~lata,

Juniperus vir~$_n~ana, Car~3~ texans and Rhus copallina. Although

the herbaceous flora is poor in number of species, many of the

species present are extremely abundant, for example, AndropogOn

~, Gerardia tenuifoli__~a, CrotonoDsis elliptica and

Panicum philadelphicum. Several species of bryophytes and lichens

are also abundant. Mosses such as Hedwigia ciliata, Grimmia

~., as well as the lichen genus Cladonia, are restricted

to the rocks and thin soil of open rock e~osures. However, other

taxa, such as Dicranum ~co~~_~_, Pol_~trichum juniperin~um_, Entodon

seductrix and B_r~u~m_oseudotriauetr~_~_, are more frequent where

the soil layer is thicker. For a list of the species present

in site 3, see Table 75.

Station 31, Sites 1-2 (21 September, 1969)

~ap 26. (S ~ sect. ~, T. 31 N., R. 5 W.)

Station 31 is located on a north facing slope and ridge

about i/8 mile upstream from 2~ulltight Spring Compground (Figure

2~). Vertical bluffs o~~ dolomite (Eminence Formation) and exten-

sive rock !edces are present on the steeper parts of this slope.

Site i (150 x 50 feet) is situated near the summit of the

slope at an altitude of 760 to 820 feet and has a soil which

is rocky, eroded, and acid (pH 5.2-5.6). Nesr the upper part of

this site the slope is about I0°; however, toward its lower

side the slope becomes steep (ca. ~5~). The dominant trees,

consisting of ~uercus alba, rubra, ~. velutina, and ~ys~a

s~ivatica vat. carolinian~ form a relatively closed canopy with

60-70% of the sky obscured by leaves and branches. Understory

associates include such small tree species as Acer rubrum,

and vines. In addition, saplings of Acer saccharum and Quercus .spD.

are abundant. The herbaceous flora is widely dispersed and includes

a number of species that are typical of upland sites with acid

soilso These are:

Galium arkans anum

Les~edeza intermedia

Antennaria ~olant a~ini£olia

Panicum dichotomum var. barbulatum

Danthonia spicata

The bryophytes and lichens present are also characteristic of

upland forests with acid soils. For a list of these taxa, as

well as other plants present in site i, see Table 76.

Site 2 encompasses about a 200 foot wide strip extending

from the edge of the river (alt. ca. 720 feet) to the lower part

of site i (alt. ca. 760 feet). The slope is very steep, varying

from 80° to vertical. Thus, precipitous bluffs and rock ledges

are common. The soil is rocky and the pH ranges from 7.6 near

the river, to 7.2-7.4 on the steep slope and rock ledges. Here

the forest consists of such dominants as Quercus spp., Tilia

americana, and Acer saccharum and has a canopy which ranges

from open to relatively closed (~0-70% of sky obscured by leaves

and branches). Other tree associates include Acer saccharinum

and Platanus occidentalis along the river and Acer rubrum,

Fraxinus soo., ~Juglans ni~ra and ~ s~Ivatica var. carolin-

iana elsewhere° Understory trees are abundant and include

Bumelia lanuginosa~ Cornus florida~ Juniperus vir~iniana, Sassafras

a!bidu~, Asimina tri!oba, Lindera benzoin~ and Staphylea trifolia.

The last three species are more common on the lower slope.

Shrubs and vines are common throughout the site, and of the taxa

present, the shrub Hyd.~an~ arborescens and the vine Rhus

radicans, are the most abundant. The herbaceous flora recorded

for this area is diverse with many of the species more or less

restricted to-~..~et areas at the base of the slope or even in the

river. These are:

Boehmeria c_~lindrica Bidens connata

Justica americana Leersia oryzoides

Station 32. (21 September, 1969)

Nap 26. (S ~ Sect. 3~, T. 31 N., R. 5 W.)

Station 32 (tree count only) is a large gravel bar (ca. 3

acres) located about 1/4 mile uostream from Pulltight Spring

Campground. The upper end of this bar is largely composed of

gravel in which numerous "~ash-outs" have developed, especially at

the bases of trees pushed over by flood waters. The lower end

of this bar is predominantly muddy and gradually merges with the

river (Figure 24). The center of this bar is 3-5 feet higher than

the river, has a sandy alluvial soil, and is heavily wooded. The

pH of the soil ranges from 6.8 along the muddy edges to 7.0 in

the center of the bar.

Next to the river the woody flora consists mainly of Salix

caroliniana, ~. ni~, and small saplings of Platanus occidentalis.

In the center of the bar, ~here a deep layer of alluvial soil is

developed, the forest is dense and closed with 80% of the sky

obscured by leaves and branches. Although a number of tree species

are present, the dominant species is~obviously Platanus occiden-

talis, with a conservative estimate of several hundred saplings

of this species considered to be present. The shrub ~ymphoricarpasorbicularis and the vine Parthenocissus Quinquefolia are the

leading understory species.

The herbaceous flora on this bar is very rich in species and

many are very abundant. A list of the taxa present at this

station, presented in Table 78, consists not only of the woody

taxa, but also of the herbaceous species according to the area

of the bar where they most often occurred (i.e., in water at

the edge of bar, low wet muddy areas at lower end of bar, drier

open gravel areas, and sandy alluvial soil of the wooded center of

the bar).

east-facing slope that rises 340 feet from a broad alluvial

plain (elev. 720 feet) to a narrow ridge (elev. 1060 feet).

Because of the extensive nature of this slope, six sites were

required to obtain an adequate sample.

Station 1 (tree count only) is an old abandoned field

approximately 4.5 acres in size on the highest terrace, 6-7 feet

above the river. The soil is sandy and circumneutral (pH 7.0)

and trees are widely scattered, forming a canopy of 20-40%.

A wide variety of tree species are present, but the dominant

species are Carya cordiformis, Juglans nigra, Platanus occiden-

talis, Quercus prinoides vat. acuminata, Q. alba, and Q. rubra.

The leading understory woody species are the small trees Asimina

triloba, Lindera benzoin, Sassafras albidum, as well as saplings of

Gleditsia triacanthos and the dominant trees. Shrubs and vines

are common, particularly the vines Parthenocissus quinquefolia,,

Dioscorea quarternata, and Smilax spp. and the shrub Symphori-

carpos orbicularis. The herbaceous flora is rich in species and

includes the following taxa that typically grow in worn out, old

fields: Ambrosia artemisiifolia, Digitaria sanguinalis, Tridens

flavus, Verbascum thaosas, Achillea millefolium, Elephantopus

carolinianus, inaphalium obtusifolitun and Erigeron canadensis.

However, the remainder of the herbs present are typical of

open alluvial soils. For a list of the species present in site l,

see Table 79.

Site 2 (150 x 50 feet)~is located at the base of the slope

at an elevation of 720-740 feet, ~here the soil is a sandy loam

and slightly acid (pH 6.8). Numerous large boulders of a cherty

dolomite (Eminence Formation) are present and the canopy is closed

with 80% of the sky obscrued by the crowns of the following domi-

nant trees: Carya cordiformis, Juglans cinerea Quercus alba and

~. prinoides var. acuminata. The understory is composed largely

of the small tree species Cercis canadensis, Lindera benzoin, and

Sassafras albidum. The vine Vitis aestivalis is very abundant,

climbing over the small trees and up into the crowns of the

dominant trees. The leading species of the rich herbaceous flora

are Asarum canadensis and Senecio obovatus. Mosses are conspi-

cuous on the moist shaded rocks. For a list of the plants present

in site 2, see Table 80.

Site 3 (150 x 50 feet) is located on’the lower mid,slope at

an elevation of 800-830 feet. Many large boulders of a sandy

dolomite (Gasconade Formation?) are scattered throughout on the

rocky, acid (pH 6.4) soil. The canopy is ~ariable, ranging from

20-60% of the sky obscrued by leaves and branches of Quercus spp.,

the dominant species. Except for two large trees, Quercus alba

(d.b.h. 15 in.) and ~. prinoides var. acuminata (d.b.h. 17 in.),

the trees are relatively small (d~b.h.~8 in.) and scattered.

Understory associates include the small tree species Bumelia lamu-

~_~_gs__~a, Rhamnus carolinian~, and Ulmus alata. Vines, particularly S~

lax so~., C~_~radicans, and Rhus radicans, form extensive and

at times almost impenetrable thickets. Herbaceous species are

abundant, especially in the open rocky areas, with 2 g~nera of the

Compositae, So___l~ida~p and As__t~, very common at this season of the

year. Solidago buckle~, for example, dominates the a~eas where

thin soil has accumulated on the surface of large boulders, a

habitat it shares ~ith EuDhorbma corollata, ~splenium platyneuron,

and Bromus up_~_~ya~_~ns. The following mosses are present on large

boulders: Anomodon attenuatus, Hedwigia ciliata, Entodon seductrix,

and Grimmia pilifera. For a list of the ts~a present in site 3,

see Table 81.

Site ~ (150 x 50 feet) is located in a glade area on the

upper mid-slope at an elevation of 900-930 feet ~here the soil

is very rocky and circumneutral (pH 6.9). Trees are fev~ and widely

scattered, consequently the canopy is only 20-~0%. Quercus prinoides

vat. acuminata, ~. rubra, and Ulmus americana are the dominant

trees present, ~hile Cornus florida, Sassafras a!bid~um~, and

Viburnum prunifolium are the leading small tree species. The

remainder of the understory includes Rhus aromatica and Ceanothus

americana, the dominant shrubby taxa, as well as the vines Smilax

bona-nox and Parthenocissus ~__inquefolia which are very abundant

and, as in site 3, form almost impenetrable thickets. The her-

baceous flora is characteristic of open glade forests and the

dominant species are Galium concinn~m, Rudbeckia hirta, ~ilphium

terebinthinaceum, Aster Drealtus, Houstonia ni~ricans, Helio~sis

helianthoid_~es and Panicum boscii. Bryophytes are common, espe-

Site 5 (I00 x I00 feet) is an open forest (canopy 20-30%)

situated just below the ridge at an altitude of 970-990 feet.

Here the soil is rocky and circumneutral (pH 6.9) and the domi-

nant trees are Carya texana, Pinus echinata and ~uercus

including rather large individuals of Pinus echinata (d.b.h. 15

and 16 in.) and Quercus stellata (d.b.h. 17 and 19 in.). The

understory is dominated by the vines Parthenocissus quinquefolia,

Rhus radicans and Smilax bona-nox. The leading herbaceous taxa

are Danthonia s_~_~ata, Potentilla simplex, Tephrosia yirginiana,

Asplenium platyneuron, Aster ~rae~ltus, Liatrus squarrosa,

Parthenium hi~p__idum, Silphium asteriscus, ~. terebinthinaceum

and Solida~o ulmifolia. Exposed rocks are covered by the

abundant growth of the mosses Grimmia pilifera and Hedwi~ia

ciliata. For a list of the species noted in site 5, see Table 83.

Site 6 (tree count only) is located on the narrow ridge

at the summit of the slope (alt. ca. 970-990 feet). The area

of the ridge sampled has a lO° slope to the north and its

soil is eroded, thin, rocky and acid (pH 5.2). Trees are

numerous and form a canopy of 60-80%. The dominant tree species,

Carla texana, Pinus echinata, ~uercus alba, ~. rubra, and ~.

stellata, are characteristic of a pine-hardwood climax (sensu

Steyermark, 1940). The trees are variable in size and with

only one exception, saplings of the dominants are present in

the understory. Cratae6us sp., Comus florida, and Sassafras

albidum are the dominant understory trees, while Vaccinium

vacillans is the most common shrub present. The herbaceous

flora is sparce but does include abundant individuals of the

specie~s Danthonia soic~t_~a, Antennaria planta~i~ifolia, Aster

patens, Nonarda russeliana, Sil~hium terebinthinaceum, and

Tephrosia vir~iniana. Dicranum ~ is the most common

near Pulltight Spring and at its base a small spring emerges

from a crevice in the vertical rock and flows directly into the

river. Because of the precipitous nature of this area, the

data for this station was obtained by study with field glasses

from across the river.

The height of this bluff and steep slope is approximately

90 feet and vertical exposures of a cherty dolomite (Eminence

Formation) alternate with very steep and narrow talus slopes.

The tree that appears to be dominant from the base to the s~mmit

is Quercus prinoides vat. acuminata. Tree associates of the

lower slope are Ace_~r saccharinum,A, saccharum, Tilia americanum,

Ulmus rubra, Alnus serrulata, Asimina triloba, Lindera benzoin,

and Platanus occidentalis. On the steep ledges and bluffs of

the mid slope Asimina triloba, Cercis canadensis, Cornus florida,

and C. drummondii are the dominant understory trees. Near the

top on the upper bluffs and ridge Quercus alba, Q. rubra and

Celtis tenuifolia share dominance with Quercus p~inoides var.

acuminata.

The shrub Hydr...angea arborescens is abundant on the mid to

upper slope, especially in crevices of the vertical rocks, while

the vine Vitis aestivalis is abundant throughout the bluffs and

slopes. Along the edge of the river the shrub Ph~socarpus

opulifolius is conspicuous.

The herbaceous flora visible was mostly that ,near the edge

of the river or on the bluffs. Justica .a~. ericana, Ss~z~rus

cernuus, Onoclea sensibilis, Uniola latifolia and Leersia

oryzoides are abundant in or near the river, while Adiantum

capillus-veneris is abundant on the moist vertical rocks above

the spring. On the bluffs and rock ledges Heuchera sp.,

Aquilegi~ canad~sis, Solidago radula and Lobelia siphilitica are

conspicuous. The moss G,ymnostomum sp. forms extensive tufa on

the moist vertical bluffs. For a list of the species noted at

Station 36 (27 September, 1969)

Nap 28. (Sect. 20, T. 30 N., R. 4 W.)

Station 36 consists of a single site sample (150 x 50 feet)

in a river bottom forest across from the mouth of the spring

branch of Round Spring. It is on the first terrace, about

lO-12 feet above the Current River (Figure 25). The soil is

well drained, sandy and slightly acid (pH. 6.4).

The dominant trees of this forest are Acer sacchartun, ~uercus

coccinea, Q. prinoides vat. acuminata, Tilia americana, and Ulmus

rubra. These trees, together with Carya cordiformis and Fraxinus

app. form a closed (ca. 80%) canopy. The understory is composed

of numerous small trees of Asimina triloba, Car~inus caroliniana,

Celtis occidentalis, Comus florida,Lindera benzoin, Sassafras

albidum, Viburnum prunifolium and saplings of the crown dominants.

Several vines trail over the undergro~th and up into the crown

of the forest and include Parthenocissus quinquefolia, Campsis

radicals, Rhus radicans, Smilax bona-nox, S. ~amnoide8 var.hispida,

S. herbacea, and Vitis aestivalis.

The herbaceous flora is abundant and forms a luxuriant

sample.

Site i is a small (ca. 25 x 15 feet) island gravel bar at

the mouth of the sp~ing bran~. The soil is a very wet gravel

mixed with sand that has a pH of 7.0. The entire bar is undoubtedly

subject to frequent flooding as it is less than one foot above the

river. The vegetation of this bar is dense and predominately

herbaceous. However, the woody taxa Salix caroliniana, Populus

deltoides (saplings) and Fraxinus quadrangulata (saplings) are

present. With the exceptions of Nasturtium officinale, ~cirpus

americanus, S. validus vat. creber and Veronica comosa that are

growing mainly in the shallow water at the edge of the bar, the

herbaceous species are scattered throughout the site. For a list of

the plants found in site l, see Table 88.

Site 2 (tree county only) is an old grave! bar (5-8 feet above

the river) that has several open areas alternating with elongated

clusters of trees (Figure 26) and has a soil that is sandy and

slightly alkaline (pH 7.2). Small trees of Salix caroliniana

and Platanus occidentalis are extremely numerous along the edge

of the bar adjacent to the river. Along the spring branch and

saplings of Acer negundo are abundant. Small trees of several

species, Cercis canadensis, Gleditsia triacanthos, Juni~erus

vir~iniana, Robmnia pseudoacac~ and Ulmus rubra, occur in the

ooen fields. In addition, the shrub Symphoricarpos orbicularis is

very abundant in these open fields where there is also a luxuriant

growth of weedy herbs that include the following dominant taxa:

Ambrosia artemisiifolia, Panicum oligosanthes, Saponaria officin-

alis, S]?orobolus clandestinus, Artemisia caudata, Centaurea

maculosa, Elymus virginica, Eupatorium rugosum, Lespedeza cuneata,

Mirabilis nyctagines, Scrophularia marilandica, and Vernonia

are very co~on. For a list of all the plants noted in site 2,

see Table 89.

Station 75, Site !-~. (28 September, 1969)

~ao 29. (~% Sect. l?,

Station ~8 is located on a narrow ridge and steep north-

facing slo;De and bluff above the Current River, ca. ~ mile ~est

of Twin Rivers. The rocks present in the soil, as well as those

forming steep vertical bluffs, are a cherty dolomite of the

Eminence Formation.

;Site i (150 x 50 feet) is on the ridge at an elevation of

800 feet, or about 220 feet above the river. The soil is rocky,

covered with a layer of leaf mold, and acid (pH 6.4). ~ canopy

of ?0-80~,~ is fo._me~ by the dominant trees, ~rya texana, Juglans

present, it t~.~ould appear from the relatively closed canopy that

this species ~.~ould not be expected to increase in importance and

that this forest could unquestionably be classified as an oak-

hickory climax type. The understory is dominated by saplings of

the cro~.m dominants and the smal! tree species Cercis canadensis,

Cornus florida, Prunus serotina, and Sassafras albidum. Vines

and shrubs are scattered throughout the area with the most

conspicuous tampa being the vines, Parthenocissus quinquefolia and

Because the soil is covered by a rather heavy leaf mold, bryo-

phytes are restricted to tree bases and logs. For a list of these

taxa, as ~,~ell as all other plants present in site i, see Table 90.

Site 2 (!50 ~ 50 feet)~located on the upper part of the steep

(ca. 65°), rocky slope at an elevation of 760-7~0 feet, has an acid

(pH 6.0) soil that is, in s~ite of the steepness of the slope,

covered by a thick layer of fallen leaves. The dominant trees,

Carya texana, C. tomentosa, Nyssa sylvatica vat. caroliniana,

(~uercus alba, .%. rubra, and <~. velutina, form a closed canopy ofO!80-90~. Although the understory is dominated by Acer rubrum,

Amelanchier arborea and Cornus florida, it also contains saplings

of most of the dominant trees as well as Acer saccharum. Other

species considered to be abundant are the vines Parthenocissus

quinquefolia, Vitis aestivalis and Rhus radicans, as well as the

shrubs Rhus aromstica and Vaccinium vacillans. The herbaceous

flora is poor in species, but those that are present are, for the

most part, abundant. This is particularly true of the ferns

Polystichum acrostichoides and Adiantum oedatum, and the flowering

herbs oolm~o caesms, Cuni~a origanoides, Desmo~um sop and

Galium spp. Bryo~2hytes are numerous on the rocky soil, rock

In addition to the saplings of both understory trees and crown

dominants, a number of saplings of Ulmus rubra and Carya cordi-

formis are present. Furthermore, the shrub Hydrangea arborescens

is very abundant, gro~ing both on the rocky soil and the bluffs and

the vines, Parthenocissus_~uinquefol~a_~ Rhus radicans~ and Vitis

aestivalis, are very numerous. ~he herbaceous flora is typical

of rich north facing ~oo~ed slopes and the following are the

Station 79 is located on a south~.~est to east facing

rhyolitic knob along the Current River just across from the

mouth of the Jacks Fork River (Fi~ure2~). ~uch of its lower to

mid elevation consists of vertical to steep sloping exposures of

felsite (Figures 28 and 30), while near the summit, extensive

areas are occupied by large angular felsite boulders (Figure 29).

The soil occurring on ledges and in crevices, is poorly developed

and acid (pH 4.6-~.6).

Site i (I00 x i00 feet) is located just below the summit~ 0at an elevation of ~0-~%6 feet and slopes about z~O~ to the

southwest. Trees are ~.~idely scattered and form a canopy of only

about 20~ (Figure 29). The dominant tree species are Carya

te~,:ana, ~_ercus stellata, and ~. velutina. Other tree associates

include marilandica, ~. alba, Ulmus rubra, U. alata, Celtis

tenuifolia, Cercis canadensis, Juniperus virginiana and small

saplings of Pinus echinata. All of the trees present in this

site ap<pear to be d<~arfed with scrubby and t~isted branches and

small, thick leaves Vaccinium~ vacillans and Rhus aromaom~a

are the leading shrubs. 9~e~.~ species of herbaceous plants grow

in the severe environment of this site, but those that d~ produce

a rather complete ground cover. Of particular importance in this

respect is the grass Andropogon scoparius, and the fern Cheilanthes

pilifera are abundant on rock surfaces, while the lichen Usnea sD.

is abundant on branches of trees, particularly Ulmus alata and

Celtis tenuifolia. For a list of the taxa present in site i,

see ~able 94.

Site 2 (150 x 50 feet) is just below the summit of the hill at

an elevation of 780-800 feet where it slopes ca. 45° to the south-

east. The soil is light, covered with a thick layer of humus and

acid (pH 5.0). In addition, small boulders of felsite are common

over the surface. A closed canopy (90%) is formed by the dominant

trees Carya te~ana, Pinus echinata, ~uercus alba, Q. rubra, and

Q. velutina. A dense understory of small trees and saplings is

produced by the following species: Carya texana, Amelanchier

arborea, Celtis ¢,ccidenta!is, Quercus sop., Sassafras albidum,

and Ulmus spD. Rhus aromatica and Parthenocissus quinquefolia

are the leading shrub and vine species. The herbaceous plants

and bryophytes recorded for this area are £ew, which is probably

a result of the combination of a closed canopy and a thick humus

layer over the soil. For a list of l~lants present in site 2,

see Table 9~.

Site 3 (150 x 50 feet) is on the steep (~0~) southwest

facing mid-slope area at an elevation of ~00-~30 feet. This

site includes not only broad areas of surface felsite (Figure ~0),

but several areas of vertical to near vertical exposures of

angular blocks of this rock (Figure 28). Soil is scant, very

acid (pH 4.6) and present only on small ledges or in rock cre-

vices. The leading tree species, Carya te~ana, Quercus mari -

~ndica, and Ulmus alata~ are widely scattered, causing the canopy

to be very open (~i0~$). Saplings of the leading trees, as

well as the small tree species Bumelia lanuginosa, Celtis occi-

dentalis and Juniperus virginiana are very common throughout the

site. The shrub Rhus aromatica and the vines Smila~ bona-nox

and Rhus radicans form a fe~ scattered thickets. ~he thin, open

soil is covered by a herbaceous flora that is dominated by the

soecies Ambrosia artemisiifolia, Andropogon scoparius, and

Cheilanthes lanosa (Figures 28 and ~0), while the exposed rocks

are covered by a dense gro~..~th of the moss species Grimmia

Site 2 (tree oount only) includes vertical dolomitic bluffs

and ledges at an elevation of ca. 650-700 feet. Few trees (six

in all) are of measurable size in a distance of about I00 feet

along the bluff and consequently the canopy is relatively open

(~0-60~). The only taxa of trees ~,~ith measurable individuals

are Acer saccharum, C_~ar_~ cordiformis, Cornus drummondii, Juni-

understory of smaller trees includes the species Asimina triloba,

Cercis canadensis, Euon~f!~~ ~~e__!a and Lindera benzoin.

Vines are abundant to very abundant with Vitis aestivalis, Rhus

Site 6 (150 x 50 feet) is on a 30° slope at an elevation

of 820-8z~0 feet where an open (canopy ca. 20%), glade-like forest

is growing. Surface exposures of dolomite are common and the

soil is thin, eroded, rocky and acid (pH 6.L~). Carya texana and

Quercus stellata are the dominant trees. Saplings of these

trees as well as Ulmus alata and .~uercus marilandica are very

abundant. The common small tree species present are Comus

florida, Diospyros virginiana, Juniperus virginiana, Sassafras

albidum and Viburnum prunifolium. The shrub flora is made up

largely of species that are typically found on upland acid soils,

such as Rhus aromatica, Symphoricarp~s orbicularis and Ceanothus

~nericanus. The rich herbaceous flora, dominated by Silphium

terebinthinaci~, Te~ohrosia virginiana, Andropogon gerardi,

Bouteloua curtipendula and Elymus virginicus, is characteristic

of open glade sites. For a list of the plants present in site 6,

see Table I0~.

Site 7 (i00 x !00 feet), a gently sloping (ca. i0-15~) area,

is located on the upper slope at an elevation of approximately 900

feet~ with a soil that is very rocky, covered by a thick layer

of leaves, and acid (pH 5.8). The forest is made up of relatively

young, even aged trees that form a canopy of ~0-80~. ~he dominant

trees are Carya ovata, C. texana, Fraxinus americana, Quercus

alba, and Q. velutina. Saplings of all of these tre~s, as well

The gravel bar of site i (tree count and reconnaissance)

covers about 3 acres ranging in elevation from 1-3 feet above

the river. It is composed of broad open areas of gravel and

narrow bands of woods, especially along the river side of the

bar. These wooded areas are largely composed of Salix caro-

liniana, some up to 9" d.b.h., and Platanus o_~c.cidentalis,___.

although some large trees of Fraxinus americanus, Betula nigra,

and Ulmus rubra are present at the lower end of the bar. The

SUPLMARY OF THE PLANT CO~T~NITIES OF THE OZARK NATIONAL

SCENIC R IVERWAYS

The vegetation of any area may be viewed from at least two

perspectives. First, there is the dynamic or successional view-

point that attempts to explain why one community is replaced by

another until a more or less permanent, stable community is

reached. A second way of viewing the vegetation of an area may

be called the static viewpoint and is mainly concerned with the

description and classification of the plant community that is

present at any given time and place. Since this study is con-

cerned with the surveying of the vegetation along the Jacks

Fork and Current Rivers, the major emphasis of the field work and

the following discussion, is of necessity, concerned with the

second vie~,~oint. This is not to say that the dynamic nature

of the vegetation has been ignored during the field studies or

will be excluded in the discussions below. On the contrary,

field observations made during the course of this survey confirm

that the general pattern of plant succession proposed by

Steyermark (19#0) appears to correlate with the results of our

data. Usefulness of his work is hereby acknowledged not only in

preparing the following summary of vegetational types, but also in

the preparation of Table 125, which is an attempt to summarize

what appears to be the general patterns of plant succession in

the central Ozarks of Missouri.

In order to prepare a summary discussion of the complex

pattern of plant communities found along the Scenic Riverways,

some grouping and generalization is obviously required, particu-

larly if such information is to be useful to the Park Service for

whom this study has been made. Therefore, the plant communities

have been divided into the following broad categories, most of

which, furthermore, can be recognized in the aerial photographs

used in preparation of the vegetational maps of the Scenic

Riverways:

While an attempt is made to arrange the first thirteen of these

community types along a moisture continuum from dry to wet, it

should be noted that the specific order is somewhat subjective

and is only a qualitative estimate of the situation. For example,

within each community type there is a wide latitude of variation

in the pH of the soil, steepness of slope, direction of slope

exposure, depth of soil, and thickness of leaf mold on the soil.

Most of these factors influence the actual moisture available in

a particular site and consequently influencing the specific com-

position of the flora of that site. Therefore, as far as the

data from this survey permits, the influence of variations of

physical parameters on the fioristic composition of the community

type is included in the following summary discussions.

i. Treeless glades. Treeless glades, commonly known as

limestone "glades" or sandstone, chert or felsite "barrens" are

scattered throughout the Ozarks. These sites are characterized

by the surface exposure of residual rocks and a treeless flora

that is largely composed of prairie species. It is generally

426.

conceded that these "glades" or "barrens" are the initial stage of

a xerosere that eventually leads to a mesic forest climax (Steyes-

mark, i.e.). If the residual rock fragments are limestone,

alkaline conditions usually prevail, and the ultimate forest

community is dominated by Aces sacchasu~ and ~uercus alba. On

the other hand, if the residual sock fragments are chest,

sandstone or felsite, neutral to acid conditions prevail a~d the

ultimate forest community is dominated by ~rcus s~. a~d

Carya spp. On sites located on narrow ridges, Pinus echinata

may be present.

An important feature of these pioneer habitats is the

presence of shallow rocky soil overlying continuous layers of

bedrock; consequently, the soil is thin, resulting in a

fluctuation of moisture extremes. Thus, the soil is saturated

with water by even moderate rainfall, only to dry relatively

soon thereafter. ~herefore, in the summer and fall, this habitat

may change quickly from one with excessive moisture to one with

excessive moisture to one with an extreme deficiency of available

water. On the other hand, in the winter and early spring these

sites are more or less continuously saturated.

The pattern of moisture availability is reflected in the

seasonal appearance of many of the glade species. In the sprin~

and early summer the appearance of these communities is domi-

nated by the fo~.lowing plants in flower:

Verbena canadensis

0enothera missouriense

Camassia scilloides

Oxalis violacea

Antennaria plantaginifolia

Castilleja coccinea

Echinacea pallida

Lithospermum canescens

Nothoscordum bivale

Some of these taxa, particularly~0xalis violacea and Nothoscordum

bivale will also bloom again, though less abundantly, in the

fall. Other plants remain dormant through the winter and spring

and bloom during the drier summer and fall. Included in this

latter group are such conspicuous flowering plants as

Agave virginica ~etaloste~on purpureum

Houstonia nigricans Gerardia tenuifolia

#27.

~osia artemisiifolia

Trichostema dichotomum

Crotono~sis elli]otica

C. tripteris

Solids.Ro soo.

Alli~n stellatum

~atorium altissimum

Silphium asteriscus

S. terebinthinacium

Liatris c~lindracea

L. asper

During this same seasonal aspect, the flo~ering of grasses

increases and they become a conspicuous element of the flora.

Those taxa most commonly present are:

Andro~sco~arius

~. ~rardii

~. vir~inicus

Sor~hastrum nutans

T__r~sicum dact~loides

Danthonia soicata

Bouteloua curti~Ddula

E__’ll~aus vir~inicus

Panicu~ virgatum

~oorobolus clandestinus

Aristida dichotoma vat.curtisii

~anicum ]>hi!adelphicum

Although the species in the above three lists are not

entirely restricted to the open glade habitat, the majority

are more abundant and. more vigorous in their gro~,zth in this

type of environment. As a result of similar observations

in other areas, several researchers have attempted to explain

this phenomenon. Erickson, Brenner and ~7raight (19z~2) have

suggested that other species are excluded from the glades and

thus cannot compete, due to the saturation of soil in the

v~inter and spring~ a condition that is conducive to winter rotting.

Quarterman (1950) has concluded, on the basis of her studies of

the glades of middle Tennessee, that the occurrence of ~et and dry

extremes excludes competing species. Furthermore, she postulates

that the reason many of the gla~taxa are restricted to this

habitat is that they are poor competitors in more favorable

zr28.

environments. %%_ether the soil is alkaline or acidic would

seem, a priori, to be an .important factor in determining the

composition of the herbaceous flora of the glades. However,

data from this study does not support this assumption, for

many, indeed most, of the taxa observed grew well in glades

with either alkaline or acid soils. Only the following species,

which seemed to be restricted to those glades with acid soils,

are an exception to this statement:

AscKrum h~ericoides

Solida~o buck!e~$~

£. iunceaAster turbinel!us

A. linariifoiius

A. natens

~richostema dichotomum

When the soil is acid, Juniperus vir~siana and ~uercus

prinoides var. acuminata are either absent or less important.

In their place, the dominant trees are usually some combination

of the following taxa:

Carla texana Ulmus alata

~uercus ste!lata Sassafras albidum

msrilandica

This shift in the composition of the dominant trees is no doubt

responsible for the differences in the make-up of the eventual

climax forests of alkaline and acid sites. In addition to the

shrubs and vines noted for alkaline sites, the following

additional shrubs are likely to be present in acid sites:

Rhus copallina, Ceanothus ~ericanus, and S_INnohoricar-pos orbi-

cularis. Examples of glades with acid soils are found at site

sample areas p~,-p, ~ ~-~., ..... n~ Z~.l-6.

The herbaceous flora of cedar @l@des is similar to that of

open 61ades.

The concept of a cedar glade as discussed above is obviously

broadly conceived and includes not only early seral stages where

Juniperus vir~iiniana and Dios~,ros vir~iiniana or Sassafras

a!bidum and Rhus conal~_ina may be the only important tree species

present, but also includes later arboreal stages that have been

6iven community ns~es such as the Bumelia !anu~in~Viburnum

rufidu!um sta6e or the Ulmus alata-Rh&~nus caroliniana stage

(e.g. ,Steyermark )- Actually, there is a continuum from the

~ery early arboreal sta~ses to the oi~en forests, to finally the

closed climax forests. In this study, -particularly in the

pre~paration of vegetational ma~’~s from aerial photo~,raphs, the

~o~ narrowly defineg seral stages is notreco6nition of these ~-~ ~

feasible.

z Bluff ~nd Rock -- -: ~ ~"~e,~e Vegetation The i~ant communities

of bluffs and rock le6~es are extremely ~,ariable because these

habitats are, in themselves~ hi~h!y variable, m.~.~ nature of the

flora of these habitats is influenced not on!y by such obvious

variations as direction of e},~posure~ type of rooks exposed, or

height of bluffs, but also by variations in such factors as the

amount of cover afforded by adjacent forests, the amount of

seep~:i,:~ (a factor controlled by local stratigraphy) and the height

of bluffs or ledges above the river. As a general rule, the flora

of north and east facing bluffs and ledges will be more luxuriant

than that of south and west facing bluffs and ledges, and bluffs

of sandstone wil! be wetter than bluffs of dolomite, limestone or

felsite. However, there are exceptions. For example, one of the

most interesting and diverse floras encountered was on the lower

part of a north facin~ .bluff at Jam-Up Cave (2~-2). Yet, a similar

f!ora ~as found on the lo~,~er part of a south facing bluff at

Station 15-1. At this latter site, extensive seepage, combined with

its nearness to the edge of the river, have produced a much more

mesic habitat than ~..~ould be e~:pected on a south facing fluff.

Because this study included only one small bluff of sandstone (i0-!)

it is not possible to make a reliable comparison between the floras

of sandstone habitats ~.~ith those of dolomite, limestone or felsite.

However, s:;udies of sandstone habitats else~..~here in the Ozarks

suggests that the major differences bet~een habitats of sandstone

and other rock ty_Des is reflected more in the composition of the

floras of ~on~ ~ es ~o~_~.,mdt~ ant ~fteridophytes than in the higher vascular

nlants.

The number of trees that gro~,7 on bluffs and ledges is

variable. If crevices and ledges are n~uerous, trees may

be common and the leading species are usually Juniperus

vir~iniana and ~uercus o,_ri_~uoides var. acuminata. Locally,

other tree species may be im]?ortant associates. These are:

Acer saccharum

A. rubrum

Carpinus corolinisna

Cornus florida

Cercis canadensis

Celtis tenuifolia

Ulmus rubra

.J~ue rcus alba

~. rubra

Fraxinus americana

F. quadrangulata

i, indera benzoin

Diosp~os virginiana

Tilia americana

Nyssa sylvatica vat.c~-~oliniana

Staphylea trTT~IT~

Asimina triloba

Viburmam prunifolium

Vines are often well developed on bluffs and the species most

likely to be abundant are Rhus radicans and Vitis aestivalis.

Smilax bons-nox and/or ~. tamnoides var. his~ida may also be

abundant, but they are usually restricted to the narrow ledges

of the bluffs. Other vines occasionally encountered include

Parthenocissus <,uinquefolia, Lonicera flays and, more rarely,

Berchemia scandens.

Of all the plants encountered on bluffs and ledges, the

shrub, ~an.Fipa arborescen~., is the species t...~ith the highest

fidelity and it is not uncommon for it to also be the most

abundant plant -oresent. Other shrubs present on bluffs or

ledges include, in decendin~ order of presence, the following

species:

Rhus aromatics

.~_2~aohormcar<os orbicularis

II~oericum soatulatum

Ribes ~7-nosbati

~R. missouriense

Andrachne D.~yllanthoides

The herbaceous vegetation of bluff’s and rock ledges varies

not only with the site, but also with the season of the year.

In the early spring, the most conspicuous and also most abundant

species present are:

Ac~uile~ia c~nadensis

Dodecatheon meadia

In the suu~uer and fal! the foilo~.~ing species are often strikingly

abundant:

Houstonia ni~ricsns

Solida~o rsdula

~. dru~m~ondii

S. buckle~i

Pol~nia canadensis

Heuchera puberula

E!~fmus virginicus

H_ystrix oatu!a

Uniola istifolia

A n~nber of ferns, restricted almost exclusively to the bluff

habitat, are present throughout the year. These are:

Pellaea atroournurea

~. ~Isbella

Ch~mlantheo feel

A. ruta-muraria var.cr~tolepis

A- t_Zl _e_ur

Included in the herbaceous vegetation of the bluff habitat

are some of the rarest plants in the Ozarks. These species, all

found at Jam-Up Cave (I0-i; 10-2), are Campanula rotundifolia,

Trautvetteria carolini~nsis, Z~gadenus ~legans, Galium boreale

vat. hyssppifo~ium and Heuchera pub erula var. glabra. ~he first

three of these species are also found at Station 40-1.

The moisture conditions of the bluff habitat is reflected

more in the composition of the herbaceous flora than the woody

flora. Althou{h drier bluffs are poorer in taxa than wetter bluffs,

they are likely to have the following species:

Cheilanthes feei

Pellaea atropurpure__~a

H_~strix-ostula

Solidago ~r~u_~ts vat. stri~osa

On the other hand, moist bluffs may include, in abundance, a

number of the following plants:

Adiantum oedatum

A. capillus-veneris

Heuchera puberula

A_~ui~_~e~ia canadensis

.H_eoatica nobilis var.acuta

Sedum sp.

Selacinel~la apoda

Nite!la ~

Dodecatheon meadia

Psrnassia ~randiflora

C~t_~_teris bulbifera

Lobelia siphilitica

Uniola latifolia

Bryophytes are often very abundant on the vertical rocks or

thin soil of the ledges. G_2~nostomtun sDo. is particularly common

along seepage lines ~.d~ere it may form thick deposits of tufa.

Other soecies likely to be common, especially on vertical rocks,

include ~momodon rostratus, _ attenuatus, iied~,~i~ia ciliata,

~orella o~_la__t~_l.l_~, Forsstroemia trichomitria, Radula andicola,

Leucodon julaceus, and ~?issicens suObasi~aris. Ho~.~ever, on the

thin soil o£’ ied~es these species may be sresent: B_.r~oandersonia

ill.e~ce~ra,Dicranu~ sabuletortm~, D. sco~r~i~um, B~ryum oseudotriouetr~m

~01~trichum .ohioense, ~-. juniper.inu~_~ Climacium smnericanum, ~dnium

cuspidatum and ~d. affine.

The presence of bluffs is not always obvious from the river

basins, for many bluffs are hidden from view by intervening

forests of bottom!ands and slopes. Bluffs may be relatively

high above the river or the river may flow abruptly against

a bluff. In size, bluffs range from only a few feet to up to

40 to 60 feet in height, and not all are sho~r.m even on the

latest topographic maps. In the course of this study, many

bluffs were encountered and north to east facing bluffs are

found at site sample areas 2-2, 6, I0-I, 10-2, 14-2, 28-1, 30-2,

31-2, 38-~, 38-4, 34, ~nc 46-3; south to west facing bluffs

are found at site sample areas 1-4, 7, i~-i, 26-1, 39-3, 41-2,

43-1, 43-2, and ~7-2.

4. Open Forests of Upland Sites. Open forests, where the

tree canopy is from 20 to 60 percent, are common throughout much

of the uplands adjacent to the Scenic Riverways. In many cases,

these open woods represent seral stages in a succession that leads

to either an Acer saccharum - ~ercus a!ba or a ~uercus - Car_~

climax. Frequently, open woods are the result of disturbances,

either from lumbering ~or cultivation; the~efore, they represent

an early phase in the reinvasion of the site by forest species.

On slightly acid to alkaline sites (pH > 6.4), particularly

on south and west facing slopes, the forest is dominated by ~uercus

l~rinoides_ vat. acuminata and/or Juniperus vir~iniana. Other tree

associates may include ~raxinus americana., F. quadrangulata, Ti!ia

americana, Acer saccharum, ~uercus a_~ba, ~. rubra, Q. velutina,

Yinus echinats:, Ulmus rubra, Carya cordiformi%, C. texana and/or

Juglans ni~ra. Ho~..~ever, some of these tree associates appear to

be more com~non on north to east facing slopes, particularly

Acer saccharum and ~uercus~ ~ albs. i~orests of this type are

frequently designs.ted as subclima~ forests (Steyermark, l.c.). On

south and ~est facing slopes where mesic species, like Acer

saccharum, are unable to survive the dry, ~,~ind swept conditions~

this subclimax sta~e may last indefinitely. In such cases the

forest dominants remain J_~u_n_ii~e__r_u~ vir~iniana, and/or .~uercu ~ s

prinoides vat. acuminata. E~.~am~ples of open forests on slightly

acid to alkaline sites are found at site sam~le areas

~ ~< ~" ~ ~-~ ~-5 and ~" ~ ~26-1, 26-2, 28-~, ~)-~, ~,~ , , ~-~.

In sites where the soil is distinctly acid (pH 6.4), the

dominant trees are likely to be Carya texans, ~uercus alba, ~.

velutina and/or .~. stellata. Other frequent tree associates include

~rubra.., ~. mariland$ca, Pinus echinata and/or N~ssa

szIvatica var. carolinian~, while less frequently, Acer saccharum

and Praxinus americana may be present. The more open the site,

the more common are species that appear to require more light for

their survival, such as Zuercus ma~il~ndic~, ~. stellata or

Pinus echiaata. As the for~s$ becomes closed, the following shade

tolerant species are more co~mmon: ~uercus veiutina, ~. rubra, Z.

alb~, Car~y_~tomentosa and/or C. texans. As a general rule, the

latter two species are more important on the drier sites (Steyer-

mark, l.c.). Examples of open forest on acid sites are found at

site sample areas 2-zr, 20-4, 24-2, ~-~, ~9-I, 4~-3, zr3-4, and

46-2.

The understory woody flora of open woods is quite variable.

Not only may it include saplings of trees such as Acer saccharum,

9,uercus alba, ~. rubra, ~..c~ ......... ste!lata, ~. velutina, Pinus echinata,

~ tomentosa, ~. cordiformis or C. texans, but many small

tree species may be common.

Celtis tenuifo!ia

Bumelia lanu~inosa

Pte!ea trifoliata

Amelanchier arbores

Cercis canadensis

Comus florida

C. dr~mondii

These are:

Viburnum prunifolium

~. rufidulum

Rhus copallina

Sassafras albidum

Dios-o~ro s vir~iniana

U!mus slats

Rhamnus carolinians

It is not unusual for many of these smaller trees species,

particularly Ulmus slats, Cornus florida and Cercis canadensis,

to be a major component of the woody flora. Shrubs frequently

encountered in open woods include Ribes missouriense, Rhus

aromatics, Ceanothus americanus, ~ori_c~2%rL~_9~_ orbicularis,

the Current River, just north of Powder Mill Perry. The soil

in this area is thin, rocky, covered with a thick layer of

humus, a~d acid, ranging from a pH of 5.4 on the ~idge to 6.0

at mid-slope. Surface exposures of dolomitic boulders (Eminence

Formation) are common.

Site I (150 x 50 feet) is located on the ridge at an

elevation of 680 to 700 feet, or about 140 feet above the river.

The canopy of the forest is closed (ca. 80%) and is dominated by

several species of Carya and Quercus. The understory of trees

is dense and composed of the small tree species Asimina triloba,

Cornus florida, Lindera benzoin, Rhamnu.s caroliniana, and

Sassafras albidum, as well as saplings of the crown dominants,

particularly Carya tomentosa and Quercus rubra. The vines Parthen-

ocissus quinquefolia and Vitis aestivalis are also imoortant components

of the understory. The most abundant individuals of a rather

poorly developed herbaceous flora belong in the genus Desmodium.

Bryophytes are also few, a condition no doubt due to the presence

of dense shading and a thick, leaf mold over the soil. For a

list of the taxa present in site I, see Table 106.

Site 2 (150 x 50 feet) is locsted on the steep (ca. 50~)

slope at an elevation of 600 to 630 feet. As in site i, the

forest canopy is dense or about 70 to 80% and the dominant

trees belong to the genera Carya and ~uercus. However, in this

site, Quercus is a more significant component, mainly because

of the presence of several rather large trees, such as i$" and

~0" d.b.h, trees of ~. alba and a 24" d.b.h. ~Q. rubra. The

leading understory tree species are the same as in site I;

however, Hydrangea aborescens, a shrub, and Parthenocissus

quinquefolia, a vine, are also very abundant. The herbaceous

flora is dominated by Desmodium nudif!orum, D. glutinosum,

Adiantum pedatum, Polystichum acrostichoides, and Galium circaezans.

Bryophytes are numerous and for a list of these plants, as well as

Station J-~5, Sites 1-5 (5 October, 1969)

Hap 3~’~. (Sect. 35, T. 29 N., R. 2 W.)

Station 4~ " ~ ms located on one of the steepest and highest

slopes (west-facing) along the Current River at the northern

end of Cardareva Bluff where the slope varies from 45° to 60°

along its lower portion to 20° to 30° near the summit. Extensive

vertical bluffs of dolomite (Eminence Formation),up to ~0 feet high,

are present along the lov~er part of the slope. The total height of

the slope and bluff is ~20 (~20-i0~0) feet.

,~zte i (150 x ~0 feet) is located along the edge of the

river up to an elevation of approximately 560 feet. The slope

is steep (ca. ,!1-5°) and the soil is rocky, sandy, and circtm~neutral

(pll ~.0). A few small bluffs of dolomite occur along the upper

part of this site, while the remainder of the site has a canopy

of 60 to o,~,,~ formed by a matu~ forest that is dominated by

Ac___e_r sacchar~,_~f~ercu__s .prinoides vat. acuminata and £uercus

rubra. ~he understory is luxuriant, made up of numerous species

of small trees, shrubs, .and vines that include the following taxa:

Acer saccharum (saplings)

Asimina tri!oba

~erc_~emma scandens (a vine)

Ca____r~9~n__u~

Comus florida

~9_u~r-~_a~ arborescens (a shrub)

Lindera benzoin

i~arthenocissus ~ quinouefoliashrub )

~uercus rubra (saplings)

~_aus radicans (a vine)

Viburnu~ prunifo lium

~he herbaceous flora, of this site is diverse, and the leading

species of the sna~ed soil are:

Anemone virginiana

Asarum canadense

Asplenium platyneuron

Aster cordifolius

Bidens bioinnata

Bo t r~c hi~ ~in i an~

On the shaded rock ledges, the following herbs occur:

Bryophytes are numerous throughout the site, particularly on

the trunks of trees, on logs and on exposed rocks. For a list of

the plants present in site !, see Table i08.

Site 2 (reconnaissance only) is located on the steep

slopes (ca. 60°) and rock ledges at the base of a high bluff

at an elevation approximately 640 to 680 feet. The thin soil is

eroded, rocky and alkaline (DH 7.a-), and subject to considerable

insolation by the afternoon sun as a result of the rather open

canopy of only 20 to p~,.~. Consequently, xermc conditions prevam±

and. the few tree species that grow here (see ~able 109) are

restricted to the deeper soils of ledges or crevices. The shrubs,

~dran:~ea arborescens and Rhus aromatica, as well as the vines

Rhus radicans and ~o~_~{£ bona-nox, are abundant. A rich herbaceous

flora is ouoooroed ~y this area an~ the.species most conspicuous in

the late fall are:

Bra~91~tr~ um erectrum

Bromus ~r~ns

E__u~o~bia__macu!ata

l-I~strix patula

Nuhlenber~a~_ frondosa

})anicum virFatum

Setaria viridis

Sol_~i~~ta vat. s__~t~~

Solida~o drummondii

S. ulmifo!ia

Verbascum ~psus

Verbesina canadensis

The bryophyte flora is primarily restricted to the vertical

exposures of rocks and the dominant species are Anomodon

a_t~tenua_~t~_,_~A, r~os__tra~us, and Forsstroemia trichomitria. For a

list of the species present in site 2, see Table 109.

Site 3 (!O0 x i00 feet),located on a .steep (ca. z~5°) slope

at an elevation of approximately ~00 to ~50 feet, has a thin,

eroded soil which is very rocky and acid (’pH 6.2). Trees are

widely scattered_ resulting in a canopy which is relatively open

(ca. ¯ ~adin~ ~arge trees belong to the species

texana, .~uercus alba, and .~. rubra. Saplings of Acer saccha.rum

and Carya texana are common, t.~i!e small trees are abundant,

particularly those belonging to the species ~arping~ caroliniana

and Ulmus alatao Rhus aromatica is the dominant shrub and Rosa. so.

a conspicuous trailing shrub. The herbaceous flora does not contain

a large number of species, but those that are present are numerous.

and Pt_~chomitrium incurvum are conspicuous on the exposed dolomitic

boulders. For a list of the plants present in site 3, see Table ii0.

Site 4 (i00 ~.~ iO0 feet) is located on the upper slope at an

elevation of about 920 to 9m.O feet ~.~here the slope is 30 to 35° and~ o "~ (DH 6.~). Boulders of a cherty dolomitethe soil is rocky an~

are scattered throughout the site and on these rocks the moss,

~ed~,~.~mg.ma ciliata, i~ abundant A cano~gy of ~-0 to 60% ms produced

by a forest in <,~hich the dominant s~ecies are ~a te}~ana, Pinus

echinata, ~ercus ~±oa., stellats, and 0 velutina ~ith the

exception of Pinus echinata, saplings of the dominant trees as

~’el! as those of iuercus r__u_br__~a are present. The understory of

small trees is thin and includes the species Amelanchier arborea,

Cerci___~s_ canadensis, Comus f!orida, and both Viburnum p~unmfol~um~ " " and

V_. rufidulum. The shrubs, Rhus aromatica and Ceanothus americanus,

m ....often the case for u~}land acid sites,are present, and. as

abundant. Herbs are scattered_ ~,.~ith the fol!o~ing members of the

Composite family most conspicuous at this time of year:

Antennaria <)]snta~inifolia

Aster anomalus

A. linariifolius

~. patens

A. turbinellus

Coreomsis oalmata

Echinacea oallida

Liatrus _l_igu!~lis

So!ida~o aitissima

~. oetiolaris

S. nemoralis

For a list of al! the 21snzs noted in site ~ , see Table iii.

Site 5 (150 x 50 feet) is located,near the summit of the

slope at an elevation of about i000 feet. This site is nearly

level and the soil is light, rocky, covered by a thick leaf

mold, and acid (pH 5.0). The canooy is 50 to 70% and. composed

largely of the crou<ns of <~uercus rubra and <i~. velutina. Tree

saplings are numerous, particularly of the species Nyssa sylvatica

vat. caroliniana, Carya texsna, Finus echinata, ~uercus marilandica
