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.

One million species threatened with extinction worldwide. That was the attention-grabbing headline that recently (and, sadly, briefly) captured the world’s attention, when the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystems Services (IPBES) released its first global assessment of how the planet’s biodiversity is faring – and what that means for people.
The Alligator Rivers yellow chat is a small, bright yellow insectivorous bird of the Kakadu floodplains. This Endangered species is imperilled by habitat changes caused by altered fire regimes, buffalo and feral pigs, rising sea levels and the spread of weeds like prickly mimosa and introduced grasses. What has been happening to degrade these floodplains has been equally of concern to Traditional Owners as to yellow chat researchers.
The central purpose of the Threatened Species Recovery Hub is delivering research that is relevant for and useable by decision-makers, land managers and others responsible for recovering threatened species. Working with partners is vital if we’re to achieve this.
The native forest on Norfolk Island provides vital habitat for the island’s threatened plant and bird species, many of which are found nowhere else on the planet (also called endemic). When the British colonised Norfolk Island in 1788, they cleared much of the original vegetation. Remaining forest is now protected in the national park and reserves, but plant recruitment is poor and invasive non-native plant species would likely overtake the forest without the on-going efforts of park managers. To preserve remaining forest, it is important to determine the main causes of declines and the most effective actions that managers can take to address these threats and restore native vegetation.
The Threatened Species Recovery Hub is celebrating great conservation outcomes from projects taking place in Booderee National Park for two Endangered species: the eastern bristlebird and the southern brown bandicoot (eastern subspecies). The Australian National University’s David Lindenmayer and Chris MacGregor give us the scoop on the bristlebird and Natasha Robinson shares the good news about the southern brown bandicoot.
