Koala Habitat Mapping pilot
The Koala Habitat Mapping Pilot was a trial of three different mapping approaches in areas of differing koala density and habitat, in Royal Camp, Carwong, Maria River and Clouds Creek State Forests.
The project assessed the adequacy, cost effectiveness and efficiency of each approach for identifying koala habitat and producing management-scale mapping for the purpose of supporting the regulation of native forestry operations on both public and private native forestry areas.
The koala habitat mapping pilot project found that the mapping methods tested could not produce an accurate, reliable and cost-effective map for the purpose of managing koala populations and habitat in a state forest context.
The results also showed that the quality of koala habitat does not restrict koala use, with koalas occupying areas beyond what is considered good habitat, albeit at lower densities. A range of variables influence koala occupancy in areas of suitable habitat, and the influence of such variables, including fire, past disturbance, roads, disease, predation and weeds, are difficult to understand and map.
In addition, the validation exercises undertaken as part of this project demonstrated some of the limitations of using ground-based surveys to determine koala occupancy.
