Individual adult koalas occupy fixed home ranges that have extensive overlap with males occupying larger ranges that overlap those of females, sub-adults, and non-breeding males.
Individual adult koalas occupy fixed home ranges that have extensive overlap.
Koala home range size varies substantially with forest structure and productivity, and males typically have larger home ranges than females. In a coastal forest in New South Wales, average home range size was 10 hectares for females to 20 hectares for males. In inland Queensland, home ranges were 100 hectares for females to 135 hectares for male.
For breeding males, the home range will overlap those of females as well as sub-adult and non-breeding males.
