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.

In only 60 years Australia has lost over 90% of a type of forest that once covered 130,000 square kilometres, and could be losing plants with important medicinal uses.
One of Northern Australia’s rarest animals will be helped by a new monitoring technique developed by a Charles Darwin University research student. Butler’s Dunnart, discovered by famous adventurer Harry Butler in 1965, is so rare it was only seen 8 times in the next 37 years.
Tiny sound recorders will be set up near the nests of South-eastern Red-tailed Black Cockatoos, as part of ground-breaking research to monitor the nesting habits of the endangered species.
Low numbers of Eastern Barred Bandicoots in Victoria have resulted in low genetic diversity which is a threat to plans to rebuild numbers in breeding programs. A new partnership is addressing the issue with an innovative breeding program which is introducing Tasmanian genes to the Victorian population.
Booderee National Park is welcoming the return of locally extinct mammals. Long-nosed potoroos and southern brown bandicoots have already been reintroduced to Booderee after being locally extinct for up to a century, and now preparations are underway to welcome a third threatened species, the eastern quoll, back to the park.
