Earlier this year the TSR Hub initiated an ambitious project to determine how a small endangered native marsupial, the Kangaroo Island dunnart, responds
when one of its prime threats, predation by feral cats, is controlled or removed. The idea, of course, is to secure a future for the dunnart but in
doing so it’s hoped there’s a whole lot more we can learn about saving threatened species. Dr Rosemary Hohnen from Charles Darwin University
is leading the work and explains here what’s involved.
Feral cats are a key cause of biodiversity loss in Australia and overseas. Across Australia there are thought to be between 2.1 and 6.3 million feral cats and they have been implicated in the decline and extinction of some 20 mammal species. Many threatened Australian mammal species now only persist in fenced ‘feral-free’ exclosures or offshore islands. The national Threatened Species Strategy has made tackling feral cats a core priority and particularly on biodiversity rich offshore islands.

With other concerned conservation biologists, researchers from the Threatened Species Recovery Hub have developed a ‘blueprint’ for management responses to the 2019-20 wildfires. This report can be downloaded from our website.
The Threatened Species Recovery Hub of the National Environmental Science Program expresses our sympathy to everyone whose life has been impacted by these horrific fires, and acknowledges the heartbreak of families who have lost everything, including loved ones.
Many landscapes in Australia are fire-prone, and increasingly so. Altered fire regimes can have a serious negative impact on threatened plant species and ecological communities. A Threatened Species Recovery Hub project is working to better understand the effects of different fire regimes on threatened flora in order to improve fire management strategies and conservation outcomes.
Almost a quarter of Australia’s possums and gliders are listed as threatened under Australian environmental law, and many more are showing signs of decline. Dr Rochelle Steven from The University of Queensland believes people in the community can do a lot to support conservation, especially in urban areas.
The detection and monitoring of threatened species have been a strong area of research in the National Environmental Science Program and also the two national environmental research programs which preceded it. Hub Director Professor Brendan Wintle takes a look at what we’ve been achieving and why it is so important to the conservation of Australia’s threatened species.
