How does the eastern bristlebird population respond to fire?
Ecological disturbance is widely recognised as a major driver of community diversity, but its role in shaping patterns of genetic diversity and population patterns has largely been overlooked.
The Threatened Species Hub and The Australian National University are seeking an environmental science student to look into this role by applying their ability to independently plan and execute field-based research. Candidates with specialist skills in genetic analysis will be considered favourably.
While the eastern bristlebird population is believed to have increased in parts of Booderee National Park since a wildfire in 2003, recent evidence suggests that it is the combination of wildfire and post-fire predation by feral predators that is the most likely reason for their decline.
The successful candidate will work closely with Parks Australia and the Department of Defence in Booderee National Park to characterise the demography and genetic structure of the bristlebird population. It is anticipated that by the conclusion of the project that the student would be in a strong position to inform fire and feral predator management strategies.

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.
