An Analysis of Demographic and Triage Assessment Findings in Bushfire-Affected Koalas (<i>Phascolarctos cinereus</i>) on Kangaroo Island, South Australia, 2019–2020
In the 2019–2020 Australian bushfires, Kangaroo Island, South Australia, experienced catastrophic bushfires that burnt approximately half the island, with an estimated 80% of the koala population lost. During and after the event, rescued koalas were triaged at a designated facility and a range of in...
