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.

Professor John Woinarski of Charles Darwin University discusses the importance of averting extinctions of less charismatic animals.
The 2019–20 wildfires have severely impacted animals of all major species groups. Here, national experts on mammals, birds, reptiles, frogs and freshwater fish and crayfish present some of the key challenges for each group and how these will influence management and research priorities in the aftermath of the fires.
Cultural fire management is the way that Indigenous people have used fire to care for Country for thousands of years, and it continues today. The devastation wreaked by the 2019–20 bushfires across millions of hectares was a wake-up call for Australia and the world. Oliver Costello from the Firesticks Alliance explains how the fires demonstrated the need to listen to and care for Country.
Australia has one of the highest rates of plant endemism of any country globally. After the catastrophic fire season of 2019–20, Dr Rachael Gallagher and Professor David Keith are leading two teams to find out which species and ecological communities are most in need of immediate recovery.
The 2019–20 bushfires burnt over 12 million hectares of south-eastern and south-western Australia, causing abrupt losses of biodiversity at a scale never seen before. Over a billion animals were estimated to have died, but the figure is likely much higher. The Australian Government’s Wildlife and Threatened Species Bushfire Recovery Expert Panel is guiding the work of prioritising species and ecological communities for emergency interventions and determining what those actions should be. Hub Deputy Director and Expert Panel member Professor Sarah Legge takes us though the hows and whys of this prioritisation, and some of its challenges.
