| description | The population of the endangered southern greater glider (<i>Petauroides volans</i>) is rapidly declining across coastal lowlands in New South Wales, Australia. Here, we focus on a typical coastal lowland glider population in Seven Mile Beach National Park, New South Wales, that is declining primarily due to habitat fragmentation. This study aimed to assess the population’s status and viability in order to guide conservation efforts. Using the double-observer distance sampling method, we estimated the population size to be 347 gliders, with a density of 0.46 gliders/ha. Population viability analysis revealed a high extinction risk, with only a 1% chance of survival over the next 50 years. Fire was identified as the primary threat, followed by a low effective population size and inbreeding. The most effective conservation strategy involved genetic reinforcement through possible translocation and the installation of up to 50 nest boxes to improve habitat (hollow) availability. |
