Australia has had remarkable success with saving species otherwise doomed to extinction – including the Kangaroo Island Glossy Black-Cockatoo, Norfolk
Island Green Parrot and Gilbert’s Potoroo.
Glossy Black-Cockatoos were headed for extinction twenty years ago. The ageing flock of 150 birds scattered among Kangaroo Island’s remaining casuarina trees was not being replenished by younger members.
A combination of research, investment and dedication revealed a previously unrecognised threat - possums. By protecting nest hollows with corrugated iron collars and trimming the foliage of neighbouring trees, nesting success was doubled. Today the population has nearly tripled, with a good chance of continued growth.
Australia’s success stories are worthy of celebration and study, and Project 6.4 will translate research lessons into concrete guidelines for recovery teams, explains Project Leader Professor Stephen Garnett.
“We’ll also learn from the failures - species have been lost that could have been saved. Christmas Island lost its last tiny pipistrelle bat in 2009, and the Bramble Cay native rat hasn’t been seen since 2007,” says Professor Garnett.
“We need to learn lessons from these extinctions - how did species fall through the safety nets of legislation and policy? What systems failed and why? How can we be sure further extinctions can be avoided?
“Monitoring the processes behind recovery may be just as important as monitoring threatened species. This includes pressures placed on individuals, the support mechanisms in place and even different world views - sometimes it is a fear of failure itself that has led to fatal inaction.
“As well as requiring top class science, effective leadership, local commitment, time and substantial investment – organisational governance, resourcing and leadership often appear to influence outcomes. How these interact should emerge over the coming year.”
One element sure to be discussed will be the makeup of successful recovery teams – whether they’re more likely to include advocates as well as managers, and the role NGOs with an interest in conservation can play in ensuring transparency.
Guidelines produced through this project will support the national Threatened Species Strategy by identifying improvements to the recovery process and ultimately increasing the chances of conservation success.

Northern Australia’s mammals have suffered catastrophic declines over the last 30 years. A major new study has found that protecting and recovering habitat by improving fire management and reducing feral cattle, horses and buffaloes is the best approach to address the crisis.
Fire is a complex, important and pervasive ingredient in the ecology of Australia. It destroys life but brings renewal. Professor John Woinarski of Charles Darwin University discusses the catastrophic losses of the 2019–20 fires, and how we can move on from mourning to action that can limit such future devastation.
Clare is a Biodiversity Field Officer with the Australian National University’s Sustainable Farms project. She tells us how she came to this role after an early life on farms in the UK, some bullet-dodging and globe-trotting.
The box gum grassy woodlands once stretched across south-eastern Australia, but have been reduced to less than 5% of their former extent. Holly Vuong speaks with Ann Kristin Raymer and Heather Keith of The Australian National University (ANU) about their new research, part of ANU’s Sustainable Farms, on developing ecosystem accounts for the woodlands to understand why this threatened ecological community is so valuable.
To help land managers get the best outcomes from their fox control investments, a collaborative project funded by the Threatened Species Recovery Hub and Victorian government agencies has developed a new fox population modelling tool. Dr Bronwyn Hradsky of The University of Melbourne led the project and is now working with agencies to apply the tool across Victoria. Here we discuss FoxNet and its applications.
