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.

There are 27 different types of possums and gliders in Australia. They have a huge variety of sizes, shapes and appearances. We’ve compiled a profile on every species here. One quarter of our possums and gliders are listed as threatened under Australian environmental law. Help their conservation, be a citizen scientist: you can record sightings of possums from your local areas in the free 'CAUL Urban Wildlife App'.
Pet and feral cats together are killing over two billion reptiles, birds and mammals per year in Australia, and most of these animals are natives, according to a new book written by three of Australia’s leading environmental scientists. The book, "Cats in Australia: Companion and killer", compiles key findings from hundreds of studies and management experience about cats across Australia.
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.
