About This Species
The Eastern quoll (Dasyurus viverrinus) is a medium-sized carnivorous dasyurid marsupial native to Australia. Once common across much of the continent, they are now restricted to Tasmania, having been declared extinct on the mainland in 1963. Aussie Ark recognises the Eastern quoll as a keystone species, playing a vital role as a scavenger and natural predator, maintaining balance within its ecosystem.
Threats They Face
Eastern quolls face significant threats, contributing to their endangered status:
Mainland Extinction: The primary cause of their mainland extinction in 1963 is attributed to the introduction of feral predators, such as red foxes and feral cats, as well as other factors like roadkill, poisoning, and trapping.
Tasmanian Population Decline: Even in Tasmania, where they persist, quoll numbers have declined by over 50% in the decade leading up to 2009, with no signs of recovery.
These threats highlight the precarious situation of Eastern quolls and the urgent need for conservation efforts.
How Aussie Ark Is Helping
Aussie Ark is at the forefront of Eastern quoll conservation efforts, with a focus on establishing and maintaining a robust insurance population:
Mainland Insurance Population: Aussie Ark has established the largest mainland population of Eastern quolls, acting as a crucial insurance against further declines in Tasmania.
Reintroduction Programs: Aussie Ark is actively involved in reintroduction programs, returning Eastern quolls to suitable habitats on mainland Australia, such as Booderee National Park in NSW.
Tasmanian Quoll Conservation Program (TQCP): As part of the TQCP, Aussie Ark continues to grow its protected and genetically robust population within specialized facilities.
Wild Sanctuaries: Aussie Ark has established wild sanctuaries, like the 400Ha sanctuary, to provide a natural environment for Eastern quolls and prepare them for potential reintroduction.
Commitment to Small Mammal Conservation: Aussie Ark is committed to conserving Australian small mammals, particularly those found along the Great Dividing Range, with a goal of restoring the area to its pre-European settlement state.
