Gymnobelideus leadbeateri (Leadebeater's Possum)

Wikipedia Abstract

Leadbeater's possum (Gymnobelideus leadbeateri) is a critically endangered possum largely restricted to small pockets of alpine ash, mountain ash and snow gum forests in the Central Highlands of Victoria, Australia, north-east of Melbourne. It is primitive, relict, and non-gliding, and, as the only species in the petaurid genus Gymnobelideus, represents an ancestral form. Formerly, Leadbeater's possums were moderately common within the very small areas they inhabited; their requirement for year-round food supplies and tree-holes to take refuge in during the day restricts them to mixed-age wet sclerophyll forest with a dense mid-story of Acacia. The species was named after John Leadbeater, the then taxidermist at the Museum Victoria. They also go by the common name of fairy possum. On 2 Mar

EDGE Analysis

Leadbeater’s possum is a small arboreal marsupial that was not sighted for 50 years and believed to be extinct prior to its rediscovery in 1961. The possum is the only marsupial endemic to Victoria, and has been adopted as one of the state's two faunal emblems. The species’ entire distribution in the wild is restricted to a 70 x 80 km area. Populations are predicted to undergo substantial declines owing to a lack of mature trees with hollows that provide diurnal den sites for possum colonies. As a consequence, the species is listed as ‘Endangered’.
