Abstract
A report in Wildlife Research, that koalas are extinct in most of the Eden region as a result of climate change, logging and clearing, is mistaken. Its recommendation, that logging should cease in a climate refuge where, supposedly, the last koalas persist, has been adopted by Government. Koalas are unlikely to benefit. It would be better to conduct radio-tracking studies of koalas in this area and in the wider region to inform their future management.
