Evidence-based management protocols for recovery of multiple threatened woodland birds
Project Leaders: Martine Maron, Jonathan Rhodes, James Watson, Jessica Walsh
Research in Brief
Eastern Australia’s temperate woodlands have been significantly cleared, with 80% of their former extent already gone, and the classically Australian woodland
bird community that is inseparably bound with them disintegrating.
This project will identify the most cost-effective actions for restoring the woodland bird community by harnessing and synthesising existing research
activities and collecting data across a large swathe of the temperate woodland zone. We will identify both costs and effectiveness of management actions
that benefit not just individual threatened bird species, but the entire woodland bird community.

Why is the research needed?
A large suite of endemic Australian birds relies on these temperate woodlands. Over 40 species are threatened with extinction at state or federal
levels, including EPBC-listed species such as the regent honeyeater and swift parrot. Of the woodland that remains, only a small fraction supports
a fully intact suite of woodland birds. Restoring Australia’s woodlands is crucial not only for the many threatened bird species that rely on them,
but for the long-term functioning of the woodlands themselves.
With such a large number of co-occurring species under threat, developing integrated approaches that cost-effectively benefit multiple species
is key. These management actions could include:
- Increasing the quantity, quality and connectivity of habitat through restoration
- Reducing ongoing habitat loss and degradation through stewardship and landowner engagement
- Removing the native Manorina species (e.g. noisy miners) from habitat patches.
However, despite large monitoring efforts and ongoing on-ground management, we don’t yet fully understand what the most cost-effective conservation

How can the research help?
The project will identify the most cost-effective management interventions that mitigate various threats for the benefit of entire communities
of woodland birds.
Specifically, we will compare the effectiveness of typical management interventions such as revegetation, creation of nature reserves, grazing
exclusion or management and weed control in improving populations of different threatened woodland bird species, as well as the ecological community
as a whole.
This project will also develop a protocol for integrating large-scale monitoring data into decision-making processes in a standardised, objective and
efficient way. It will directly guide government agencies, conservation organisations and land owners on how to recover threatened bird species
and inform investments in stewardship activities while maintaining healthy, functioning woodland ecosystems.
This work leverages a crucial opportunity presented by the Saving our Species (SoS) program, run through the New South Wales Office of Environment
and Heritage, which includes $100 million of investment in the management and monitoring of over 300 species at over 800 sites across New South
Wales. SoS has the potential to provide a very powerful dataset for answering questions relating to management effectiveness.

What research activities are being undertaken?
This project will produce:
- Estimates of the response of individual woodland bird species and an index of the condition of the woodland bird assemblage to a range of management
- Cost-effectiveness analyses using the site-level responses of woodland birds and cost data for management interventions.
- A database and tool for pinpointing the most cost-effective suite of actions for restoration of particular species and/or the woodland bird community
for different locations and circumstances, and calculating the expected benefit from investment in future on-ground actions.
- A process for integrating adaptive management into existing on-ground threatened species programs to leverage the greatest opportunities for learning.

The researchers will be drawn from teams based at The University of Queensland, The University of Melbourne, The University of Sydney and the Australian
National University. The partnership overseeing this project includes the NSW Office of Environment and Heritage, Birdlife Australia, Bush Heritage
Australia and CSIRO.
Where is the research happening?
The research will be done across the temperate woodland zone of New South Wales.
