Leadbeaters Possum (Gymnobelideus leadbeateri)

The Leadbeaters Possum


Leadbeater’s possum is an endangered marsupial that can be found in the Central Highlands of Victoria. Prior to 1961, this animal was thought to be extinct. Leadbetter’s possum is the official faunal emblem of Victoria State. The current decline of the species is due to a diminishing habitat caused by timber harvesting and fires. In 2003, the estimate total population of this species was 500 total animals.

Forests of montane ash are the desired habitat of the leadbeater’s possum. The social structure of the leadbeater’s possum is unique to other mammals; females are dominant. A nest is inhabited by a female, her mate, her offspring, and possibly other non-related males. The female will defend her nest from any female not related to her; males in the nest will assist in defense. Scent is used to recognize family members. It is also notable that family members will groom one another. For every three males there is only one female.

The main component of the leadbeater’s possum is insects found under bark and various forms of vegetation. The leadbeater’s possum will use its teeth to slice open tree bark, which will then produce sap.

Breeding is monogamous between a pair of leadbeater’s possums and will remain that way for the entire life span. Mating does not occur in January or February, but takes place throughout the rest of the year. A leadbeater’s possum reaches reproductive maturity at two years of age. The gestation period for a pregnant female is not known due to frequent mating habits. Litters produce between one and two young. The young are weaned from the mother by three months. Young are forced to be independent of their mother (by their mother) at about one year of age.
