The spatial data maps koala populations and habitat for three study areas in the Midcoast LGA of New South Wales. The three study areas, Kundle, Khappinghat and Tea Gardens are geographically separate, and each are approximately 16, 000 hectares and square or rectangular in shape. The data maps both ‘Likely koala habitat’ and Occupied koala habitat’ on all lands except NPWS Estate and Forestry Corporation of NSW estate. ‘Likely koala habitat’ occurs where there is greater than 15% dominance of preferred koala food trees. ‘Occupied koala habitat’ is a spatial subset of ‘Likely koala habitat’ where koala populations are currently viable based upon known presence and their generational persistence over time. The maps were produced under the NSW Government's Koala Strategy in collaboration with Midcoast Council to inform Council’s 2024 MidCoast Koala Conservation Strategy.
