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.

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.
The native forest on Norfolk Island provides vital habitat for the island’s threatened plant and bird species, many of which are found nowhere else on the planet (also called endemic). When the British colonised Norfolk Island in 1788, they cleared much of the original vegetation. Remaining forest is now protected in the national park and reserves, but plant recruitment is poor and invasive non-native plant species would likely overtake the forest without the on-going efforts of park managers. To preserve remaining forest, it is important to determine the main causes of declines and the most effective actions that managers can take to address these threats and restore native vegetation.
The Threatened Species Recovery Hub is celebrating great conservation outcomes from projects taking place in Booderee National Park for two Endangered species: the eastern bristlebird and the southern brown bandicoot (eastern subspecies). The Australian National University’s David Lindenmayer and Chris MacGregor give us the scoop on the bristlebird and Natasha Robinson shares the good news about the southern brown bandicoot.
