Scientists suspect that hundreds of thousands of Australian species remain undiscovered or poorly known and that many of these species are at as great
a risk of extinction as those formally listed as threatened. Poorly-known but imperilled species present a formidable challenge to researchers and
conservation managers for many reasons.
“In most cases, the knowledge limitations for these species constrain targeted conservation responses and prevent these poorly known species being formally listed as threatened,” says Beth Crase, who recently ran a workshop for the TSR Hub’s Improving threatened species assessments and evaluating conservation policy options for data-challenged species (Project 5.2)
“We explored a range of options for enhancements to legislation, policy and process to better protect such species from extinction.”
The workshop brought together policy, management and research personnel from the Commonwealth and state governments, Commonwealth and state threatened species committees, and universities to help define the extent of the problem of conservation for poorly-known species, to develop options to enhance the conservation of these species and to document impediments, biases and opportunities.
Options for enhancing this protection included greater use of the precautionary principle; application of some specific protective categorisation currently used by the WA agency; use of a data-deficient category; comprehensive assessments of the conservation status of major taxonomic groups of species; expanded de facto protection such as inclusion in the national reserve system, in threatened ecological communities or management actions directed at key threatening processes; and increased community awareness and support for non-charismatic species.
A policy paper outlining these options will be a key output from the workshop. Other outputs will include a series of publications for peer-reviewed journals and potentially a national working list of data deficient species.

With other concerned conservation biologists, researchers from the Threatened Species Recovery Hub have developed a ‘blueprint’ for management responses to the 2019-20 wildfires. This report can be downloaded from our website.
The Threatened Species Recovery Hub of the National Environmental Science Program expresses our sympathy to everyone whose life has been impacted by these horrific fires, and acknowledges the heartbreak of families who have lost everything, including loved ones.
Many landscapes in Australia are fire-prone, and increasingly so. Altered fire regimes can have a serious negative impact on threatened plant species and ecological communities. A Threatened Species Recovery Hub project is working to better understand the effects of different fire regimes on threatened flora in order to improve fire management strategies and conservation outcomes.
Almost a quarter of Australia’s possums and gliders are listed as threatened under Australian environmental law, and many more are showing signs of decline. Dr Rochelle Steven from The University of Queensland believes people in the community can do a lot to support conservation, especially in urban areas.
The detection and monitoring of threatened species have been a strong area of research in the National Environmental Science Program and also the two national environmental research programs which preceded it. Hub Director Professor Brendan Wintle takes a look at what we’ve been achieving and why it is so important to the conservation of Australia’s threatened species.
