Improving conservation assessments and policy options for poorly known species
Project Leaders: Stephen Garnett, John Woinarski
Research in Brief
In Australia, assessments of species’ conservation status are routinely based on information such as population size and trends, distributional extent,
and threats. When a species is poorly known and these data do not exist, that species is unlikely to be assessed. It is likely that many of Australia’s
poorly known species would qualify as threatened if we had the data to assess them properly.
In collaboration with relevant stakeholders this project will develop new approaches for conservation status assessments for poorly known species, investigate
the risks and benefits of using the precautionary principle and the application of a ‘Data Deficient’ category. The results will improve conservation outcomes
for poorly known species and increase the comprehensiveness of assessment processes.

Why is the research needed?
In Australia, as elsewhere, the level of legislative protection and conservation management a species is granted is based largely on its assigned conservation
status (such as Critically Endangered, Endangered or Vulnerable). These conservation statuses reflect the proximity or risk of extinction. However, the
assignment of conservation status to any species requires a substantial amount of evidence, particularly in relation to a species’ distribution, population
size and trends, breeding success, and threats. But what happens when we know little or nothing about these things for a species?
Currently, these poorly known species are largely excluded from assessment due to lack of data. Unfortunately, it is likely that many poorly known species
would qualify as threatened if we had the data to assess them properly. Not listing these species, or significant delays in listing, may come at considerable
conservation cost: species may become extinct, or so far imperilled that recovery is unlikely, without them ever having been formally recognised as threatened
so never being the focus of conservation action.
There are some mechanisms that can be used to address this ‘lost opportunity through ignorance’ scenario. The precautionary principle – that ‘if there
are threats of serious or irreversible environmental damage, lack of full scientific certainty should not be used as a reason for postponing measures to
prevent environmental degradation’ – is an explicit fundamental principle underlying the Environment Protection and Biodiversity Conservation (EPBC) Act,
but to date it has been little used in our national process for assessment of species’ conservation status.
Unlike its global (IUCN) blueprint for conservation status assessment, the EPBC Act does not allow for a Data Deficient category and hence provides no
explicit protective mechanism, or prioritisation for research and assessment, for poorly known species.
Current conservation assessments and responses are largely biased towards charismatic and well-known animals and plants. This is likely to result in substantial
misdirection of conservation priorities, and lost opportunities for the conservation of imperilled but poorly-known species.

How will the research help?
This project will improve the conservation management of poorly known species by assessing a variety of policy and conservation actions that could be of
- Accepting expert elicitation to determine the conservation status of likely imperilled but data poor species
- Development of strategic evaluations of the conservation status of poorly-known groups of species
- Assessments of the use and limitations of the precautionary principle for threatened species listings
- Assessment of the use and value of a Data Deficient category, and of its potential applicability at national level.
This project will seek to help Commonwealth, State and Territory agencies to implement prudent conservation decision-making processes for situations in
which information deficiency currently impedes good conservation outcomes.
What research activities are being undertaken?
The research will involve a number of workshops and analyses covering:
- Expert elicitation and comparable processes for the conservation assessment of likely imperilled species for which information is limited, based on
conclusions of a workshop of varied case studies
- Risks and benefits of using the precautionary principle for listing and de-listing processes
- Potential use of a Data Deficient categorisation within legislation, and risks associated with available options for dealings with (or not dealing
with) data-limited species.
Outputs of the project will include peer-reviewed scientific papers, and reports to the Threatened Species Scientific Committee, and to relevant Commonwealth,
State and Territory agencies.
Who is involved?
This project is being led by Charles Darwin University who are working closely with Australian Government teams involved in the assessment and listing
of threatened species, and with the Threatened Species Scientific Committee.
Where is the research happening?
The research and workshops will have a national focus. No field work is involved.
When is the research happening?
This project began in 2016, and will run until December 2018.
