Welcome to Friends of Leadbeater's Possum

About Leadbeater's Possum

Leadbeater's Possums can be viewed at Healesville Sanctuary in its nocurnal enclosure. Leadbeater's Possum was presumed extinct by 1960 simply because no live specimen had been seen for 50 years. Then, in 1961, a single possum was rediscovered by naturalist Eric Wilkinson near Marysville, 90 minutes east of Melbourne - a far cry from its original known habitat in Gippsland. Previously, the last captured Leadbeater's Possum was from 1909. Since it's rediscovery a great deal of interest, research and awareness has been raised by Victoria's zoos, biologists, community groups and citizens. In 1968 it was made the official faunal emblem of Victoria. Also known as Fairy Possum, the Leadbeater's Possum is a tiny, nocturnal creature with large eyes and a long tail measuring around 10 to 15cm in length. It requires old growth eucalypt trees with established hollows for its home. As a result it is now located in small pockets of old growth Mountain Ash forest in Victoria's Central Highlands from Toolangi, near Kinglake, to Powelltown, near Warburton. Leadbeater's Possum numbers are estimated to have peaked in the mid-1980s, when approximately 7500 were known in the wild. From then, it's numbers have declined. Logging has impacted on its habitat and range. Devastatingly, the Black Saturday bushfires of 2009 burned around 45% of its remaining habitat. There is now estimated to be around 1500 Leadbeater's Possums remaining and it may soon be admitted to the critically endangered list. Since 2009 there has been renewed scientific and community interest. A breeding program at Healesville Sanctuary is hopeful of seeing results in the near future and understanding more about Leadbeater's socialization and habits. Various community groups, including Friends of Leadbeater's Possum, My Environment and Great Forest National Park continue to champion for Victoria's fairy possum and liaise with both government and industry to create a safe haven. There is hope that some time soon a national park, the Great Forest National Park will be established that will provide Leadbeater's possum with a more stable future. We celebrate Leadbeater's possum in 2015 and trust you will too.

Update from the field

The Leadbeater’s Possum population at Lake Mountain

Leadbeaters-Painting-Liz-Cogley2_1024wSurveys initiated in 2003 indicated that sub-alpine woodland on the Lake Mountain plateau supported a substantial Leadbeater’s Possum population (~ 200-300 individuals) prior to the 2009 Black Saturday wildfire. Following the fire, just two family groups (5 individuals) remained. Late in 2011, 6-7 individuals were being monitored and supplementary fed on the plateau. Following the rapid disappearance of four of these possums, probably due to predation, the decision was made to remove the remaining three individuals to captivity at Healesville Sanctuary on welfare grounds (they are now on display in the nocturnal house at Healesville Sanctuary). Camera trapping surveys conducted following the removal of these possums confirmed that no Leadbeater’s Possums remained in that part of the plateau. It was thought that vegetation recovery permitting Leadbeater’s Possum recolonization of the plateau may take approximately 15 years (i.e. ~ 2025). In April 2013, nest box monitoring and stagwatching confirmed that two Leadbeater’s Possum family groups had returned to the plateau far earlier than expected, albeit both were associated with tiny patches of vegetation burnt at lower severity. Each group contained two individuals, and one of these groups had taken up residence in the partly burnt territory where the three possums were removed for captivity one year earlier. The 2014 monitoring was completed in early April and confirms the ongoing presence of one of these two family groups, which now contains three individuals. The second possum family was not detected in any of the nest boxes, however fresh nesting material was found below one of the nest boxes indicating the ongoing presence of possums in this area. Extensive genetic sampling of Leadbeater’s Possums at Lake Mountain was completed prior to the 2009 fire. The individuals that survived the fire were sampled in 2011, providing the opportunity to monitor changes in genetic diversity arising as a result of the fire. A comparable monitoring program is underway for Leadbeater’s Possum on the neighbouring Mt Bullfight Plateau, where small clusters of family groups survived the 2009 fire in three distinct areas. The viability of these small, isolated groups of possums is uncertain, and is a key question in understanding how this species responds to wildfire.

Now there are 200 nest boxes in place. Thank you to our generous supporters.
