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.

The hub is undertaking a nation-wide assessment of the conservation status of every Australian eucalypt species. To commemorate this achievement we are holding a photo competition to celebrate the beauty and diversity of Australia's eucalypts. Entries close 22 July 2019.
Do you have data on threatened or near-threatened Australian birds, plants or mammals? Please send it in by 15 June 2019 and it will be used to update Australia's first ever threatened birds index and to create indexes for plants and mammals by the end of the year.
Many of Australia’s possums and gliders are under threat. Good information about where different species are greatly assists conservation programs. Members of the public can play a valuable role in helping to collect this information in their own backyards, and surrounding parks and natural areas.
Red foxes are one of the greatest threats to Australia’s native mammals and pose a major risk to livestock. To combat this, Australia spends more than $16 million per year on red fox control, with much of that money directed to poison baiting.
An international study led by The Australian National University has found a fungal disease has caused dramatic population declines in more than 500 amphibian species, including 90 extinctions, over the past 50 years.
