A harmonised map of potential koala habitat was developed for the region encompassing Queensland, New South Wales (NSW) and the Australian Capital Territory (ACT). This map represents the area (ha) and presence of koala habitat in 100ha planning units across this region. The area of habitat is equivalent to the percent coverage of habitat in each planning unit. The map was developed by harmonising existing regional habitat mapping and range-wide and regional species distribution models. Additional models of koala habitat were developed for regions where datasets of koala habitat were not available.
