Vegetation condition is also referred to as

quality, health, intactness or naturalness

We need vegetation condition to help

inform decisions about land management

and biodiversity conservation

• Vegetation structure or

composition ( = type)

• Vegetation configuration

• Vegetation extent

Key Points

• transformed existing floristic records to

describe the structure and composition of

a site,

• delivered a spatially explicit representation

of nine vegetation attributes,

• used to inform a range of ecological

applications, including assessment of

whole of landscape condition status
