Meet the endangered Northern Bettong

We are pleased to share some incredibly rare images of one of Australia’s most endangered mammals, the Northern Bettong, ahead of a major AWC project to reintroduce the species at Mt Zero-Taravale Wildlife Sanctuary, in north Queensland.

This little marsupial has been identified as one of the mammal species at greatest risk of imminent extinction, and it is estimated that fewer than 1,150 individuals remain. Learn more about these beautiful animals, and our plans to help save them, by exploring the pictures below.

 

Meet the Northern Bettong

The Northern Bettong is a small, grey, lightly-built macropod with a black crest on the end of its tail. It holds its front paws closely to its chest, and moves with a low, distinctive springy hop.

Northern Bettongs grow to just over 30 cm, with a tail to 34 cm, and an average weight of 1.2 kg.

 

The Northern Bettong lives in a narrow band of tall, open forest which fringes Queensland’s Wet Tropics rainforests. In these forests, the bettongs forage for underground fungus (bush truffles), providing an important service as they feed by dispersing ectomycorrhizal fungi which help nourish eucalypts and other tree species.

The northern bettong is a keystone species, responsible for the dispersal of a huge number of species of ectomycorrhizal fungi, which play an essential role in forest health.

 

Sadly, feral cats, habitat loss and changed fire regimes have led to the bettong’s decline. Two of the four remaining populations have disappeared in the last twenty years.

Feral cats occur throughout the Northern Bettong’s range and have caused declines of bettong species throughout Australia.

 

The small size of the remaining populations of Northern Bettong mean they are especially susceptible to extinction, and the isolation of remaining populations means that natural recolonisation of suitable habitat is unlikely.

 

Restoring the Northern Bettong at Mt Zero-Taravale

One of AWC’s objectives when we purchased Mt Zero-Taravale was to protect the Northern Bettong.

Threats to the northern bettong include feral predators and herbivores, inappropriate fire regimes and climate change.

 

We are now collaborating with Traditional Owners, Queensland Parks and Wildlife Service, the Wet Tropics Management Authority and landholders on the Northern Bettong Recovery Team to carry out an ambitious project that will re-establish the species within its former range at Mt Zero-Taravale.

AWC’s 18 years of land management at the sanctuary has seen feral herbivores removed, weeds reduced, and targeted work to restore the structure of the wet sclerophyll forest.

This has been achieved through selectively thinning the woody understorey and reintroducing a healthy regime of regular, low-intensity fires to let the sunlight in and promote the recovery of native grasses.

The open grassy understorey of the tall eucalypt forests, key habitat for the Northern Bettongs, is being recovered through  land management efforts, as well as by a targeted program aimed at reducing ‘woody thickening’ and rainforest invasion.

 

The next step is constructing a conservation fence to exclude predators from a 950-hectare area within the wet sclerophyll forest.

We hope to return the first Northern Bettongs back to Mt Zero-Taravale in 2021, and ultimately to rebuild a secure, genetically diverse population. We are grateful for the generous contribution by WIRES toward this project.
