Australia has a high rate of extinctions. The rate of loss is continuing, unabated. Some recent extinctions have occurred without relevant managers having
sufficient foreknowledge the species is close to disappearing.
“The problem is that the Australian threatened species list, which is what most conservation managers and policy makers refer to, is failing to keep abreast of the actual rate of biodiversity loss,” said Professor John Woinarski from Charles Darwin University.
The Threatened Species Recovery Hub’s Project 2.1 will work to ensure that policy makers and project managers have more reliable and up to date information about species closest to extinction.
“There should be no regrets or surprises. If all the relevant ministers, policy makers and project managers are aware of a high extinction risk, then they
have an opportunity to avert it.”
Led by Professors John Woinarski and Stephen Garnett, the Project will develop mechanisms to complement the Australian threatened species list to help reduce the risk of further species’ loss.
“It’s remarkable how rapidly some species have disappeared, and sometimes it’s hard to predict. The forest skink on Christmas Island is a classic case – it was only officially recognised as threatened five months before it was extinct,” said Professor Woinarski.
Researchers will identify fauna species facing imminent risk of extinction and work with on-ground management agencies (state government, NGOs etc.) to identify and prioritise management responses.
“We will also be looking to work closely with the Hub’s monitoring project. A better handle on a species’ current population trajectory provides more confidence about estimating the risks and likelihood of extinction.”
“Initially we’ll develop modelling to predict extinction risk amongst birds and mammals, for which there is generally more information, and then proceed to other vertebrates and invertebrates in subsequent stages.”
“The species we’re fighting for don’t have to be the most charismatic or well known - much of Australia’s biodiversity loss has occurred in less charismatic species.”
“For all highly imperilled species, we’ll review the existing or proposed management actions and attempt to refine and improve them. At the end of this project we should have alerted all relevant ministers, policy makers and managers – there should be no excuses or surprises.”
Project 2.1 links in with other work taking place through the Hub, to provide the Minister for the Environment, Threatened Species Commissioner and Federal Department of The Environment with evidence to inform policy and on-ground threatened species management decisions.

The Christmas Island forest skink was not formally recognised as threatened until December 2013, far too late to prevent its extinction on 31 May 2014.

Kanyirninpa Jukurrpa (KJ) Rangers in the Martu Determination have collaborated with Threatened Species Recovery Hub scientists to design a monitoring program for mankarr (the greater bilby). Martu people identified priorities for the bilby monitoring program, then worked with Dr Anja Skroblin from The University of Melbourne to co-develop a monitoring method which brings together Martu knowledge and practice with Western conservation science.

A new project is aiming to increase city kids’ connections with nature, threatened species conservation and Indigenous culture. Dr Georgia Garrard from RMIT University talks about this project, which will see Wurundjeri Woi-wurrung Traditional Owners working with kids at Carlton North Primary School in Melbourne and Gunditjmara Traditional Owners working with kids at Heywood Consolidated School in western Victoria.
For the Larrakia Land and Sea Rangers, the sight of a shell midden in coastal saltpans tells a long history of culture and how their ancestors are connected with the intertidal and mangrove environment. Through a different lens, the Larrakia Rangers also see these shell middens as areas where their culture overlaps with the habitat used by the Critically Endangered migratory shorebird the far eastern curlew.
Threatened species on Indigenous land may be of prime interest to scientists and ecologists, but they are often not the species of greatest importance to the Indigenous landowners. Understanding local priorities for biodiversity is an essential step in ensuring that conservation projects are locally beneficial and supported. Researcher Tom Duncan from Charles Darwin University has been collaborating with the Tiwi Land Council and Tiwi Land Rangers to explore this issue on the Tiwi Islands.
