TSR Hub researchers Professor Hugh Possingham and Dr Elisa Bayraktarov are collaborating with James O’Connor, Glenn Ehmke and Joris Driessen from Birdlife
Australia to create the “Dow Jones” for threatened species. That is, they are going to create an index that reports on annual changes in Australia’s
threatened species populations.
Elisa Bayraktarov recently visited BirdLife Australia in Melbourne to work on the joint BirdLife-NESP database. During the two-week visit, NESP/BirdLife researchers established a strategy for data sharing, collated a database with contact information on potential data custodians for over 250 threatened bird species, and initiated a national call for monitoring data.
The researchers have already made good progress, collating incoming data from a multitude of stakeholders across the nation and for a range of threatened species.
“We are very surprised at how enthusiastic all the scientists and agencies are to share their data for a good cause,” comments Elisa, who is part of the NESP/BirdLife data management team.
Once received, the data will need to be adapted into a model-friendly format for trend analysis. The group is now working on criteria that prioritise incoming datasets for processing.
“We are collaborating with the Zoological Society of London to test their Living Planet Index method as a candidate for an Australian threatened species index”, she continues. “We anticipate having a fair amount of representative threatened species data in our integrated database to test several potential indices in our analytical workshop in March next year,” she says.
The team is now calling for any available data on threatened Australian bird species – with a particular interest in repeated quantitative measures of abundance in which survey methods and the area surveyed have remained the same over a number of years.
“Bird monitoring data exists in many forms and resides with many people, so we are currently collecting any kind of raw data on threatened birds,” Elisa explains.
“An index is only ever as good as the data that goes into it, so all data, even from very small scale monitoring programs is potentially very valuable to the research,” comments Glenn Ehmke, Monitoring Program Manager of BirdLife Australia and project collaborator.
Professor Hugh Possingham says “if the pilot work on birds works, we will expand our work to other taxonomic groups.
Ultimately we would like to see an index that can be credibly made public each year for different taxonomic groups, regions and type of threat.”

You have to be pretty lucky to make a living by combining your passion and interests, and that’s exactly how Dr Daniel White feels about his current state of affairs. Dan began his career studying genes, and has since applied his science to saving species. Here he describes how.
The TSR Hub recognises that outcomes for threatened species will be improved by increasing Indigenous involvement in their management. In response to this, the Hub is guided by an Indigenous Reference Group and has a number of projects across Australia that are collaborating with Indigenous groups on threatened species research on their country.
A new contagious fungal plant disease has entered Australia, myrtle rust. It’s highly mobile, can reproduce rapidly and is infecting many species across a broad geographic range. Containment and eradication responses have so far been unsuccessful.
Australia is losing large old hollow-bearing trees in our mountain ash forests due to logging, fires and climate change. A team at the Australian National University have been investigating the importance of these trees, the implications of their loss and things we can do to ensure we have enough mountain giants for the future.
While media reports often focus on the doom and gloom of species sliding to extinction, it is important to also take note of where we are succeeding. Hub Deputy Director Professor Stephen Garnett talks about the importance of learning from conservation successes and celebrating how far we have come.
