Map of koala movement corridors and priority restoration areas in a study area in south-western Sydney. Koala movement corridors are classified as primary, secondary and tertiary according to the level of connectivity of core koala habitat which are critical for the long-term viability of the regional koala population in the study area. Koala corridor categories also consider corridor dimensions such as minimum widths. Koala corridors are likely to extend outside of the study area. They are named, largely by geographic area or river/creek catchment. The mapping, along with key koala conservation principles, form the basis of advice by the Department of Planning, Industry and Environment related to the conservation of the regional koala population extending from Holsworthy and Moorebank, through Campbelltown and Wollondilly, to Wingecarribee.
