The conservation status of the koala in Australia is not a homogeneous entity but is subject to regional variation according to the predicament of each population with respect to disease and habitat availability. Habitat is the primary factor affecting koala population dynamics in both critical decline and expansion. Key koala management and planning decisions necessitate a regional identification of potentially suitable koala habitat. The environmental factors constituting preferred koala habitat were identified and existing GIS databases used to combine Eucalyptus species preferred and utilised by koalas with soil properties to predict optimal, sub-optimal and unsuitable koala habitat in the southern Mt. Lofty Ranges. The methodological framework is flexible and particularly suited to regional koala management in Australia.
