Hundreds of thousands of Australian species are so poorly known that their risk of extinction cannot be determined.
These species cannot be categorised as threatened or not under Australia’s EPBC (Environment Protection and Biodiversity Conservation) Act, and are therefore afforded no conservation protection under the legislation.
Research under Project 5.2 aims to investigate and propose a range of policy and legislative options to better protect these species from extinction, despite limited knowledge about them.
Such legislative options may include a more thorough implementation of the precautionary principle and the inclusion of a “Data Deficient” category in the EPBC Act, which would align Australian legislation with the IUCN (International Union for Conservation of Nature) Red List.
This project will also explore how new tools in the fields of expert elicitation and machine learning can be used to predict which of these poorly known species are most likely to be threatened. It seeks to generalise and develop sound protocols from the specific cases presented in a recent application of expert elicitation used to guide conservation status assessments for poorly known species.
New analytical approaches, such as Machine Learning have recently been used to predict the conservation status of poorly known species by training a set of mathematical algorithms using data on 'data sufficient' species. This new approach may also be explored under this project in order to help to redress the taxonomic bias in conservation assessments.
A range of stakeholders in the Australian Department of the Environment and Energy, in state and territory conservation agencies and the Threatened Species Scientific Committee are integral to this project.
The focus is Australia wide, and for both flora and fauna across all taxonomic groups.

Karajarri Rangers are leading a Threatened Species Recovery Hub research project to investigate how different fire management approaches affect biodiversity. The first field trip took place in April this year, when a team of 16 rangers, support staff and scientists journeyed to the Edgar Ranges for eight days of wildlife monitoring. Hub researcher Sarah Legge worked with the rangers to compile this report from the field.
Cissy Gore-Birch is a member of the Threatened Species Recovery Hub’s steering committee and the Chair of its Indigenous Reference Group. The Indigenous Reference Group was established to assist hub leaders and project teams to strengthen the engagement and participation of Indigenous people in the hub’s activities and research projects. Cissy recently attended the Species of the Desert Festival on the Paruku Indigenous Protected Area, where she spoke about both threatened and culturally important species, and increasing the voice of Indigenous people in environmental policies and research.
Dr Sally Box, the Australian Government’s Threatened Species Commissioner, talks about the importance of working with Indigenous groups to conserve Australia’s threatened species.
Researchers from the Threatened Species Recovery Hub are calling on citizen scientists to help them learn more about Australia’s possums and gliders by recording sightings in a new, free app. Dr Rochelle Steven from the University of Queensland is passionate about Australia’s possums and gliders and believes people in the community can do a lot to help support conservation, especially in urban areas.
There are 27 different types of possums and gliders in Australia. They have a huge variety of sizes, shapes and appearances. We’ve compiled a profile on every species here. One quarter of our possums and gliders are listed as threatened under Australian environmental law. Help their conservation, be a citizen scientist: you can record sightings of possums from your local areas in the free 'CAUL Urban Wildlife App'.
