More than 8000 islands surround Australia’s coast - from tropical to temperate to sub-Antarctic climates; from large populated islands to tiny uninhabited
“Many people aren’t aware of how many islands we have and how diverse they are,” reflects Associate Professor Salit Kark, project leader for Project 4.2: Saving species on Australian islands.
While the ecology of each island is different, native threatened island species often face similar conservation challenges resulting from the impacts of invasive species, habitat loss and other factors.
“Australia’s islands play a very important role in threatened species recovery. Not only do endemic island species need protection, but islands can also be used as refuges for species that are threatened on the mainland,” says Associate Professor Kark.
“Many of Australia’s islands are already undergoing conservation activities to protect native species, and we want to assist in developing more sharing of data, knowledge and experience.”
The Threatened Species Recovery Hub’s Project 4.2 aims to maximise conservation benefits by facilitating a more coordinated approach to island conservation at a national scale.
Work has started with a collaborative project underway at Stradbroke and Moreton Island off the southeast Queensland coastline.
Researchers and students are working with partners and stakeholders, such as the Quandamooka aboriginal people and environment groups, who are actively engaged in on-ground threatened species recovery – namely feral animal eradication.
Macquarie Island, home to thousands of threatened seabirds, is another example where Project 4.2 can maximize conservation benefits says fellow project leader Dr. Justine Shaw.
“The island recently underwent successful eradication of three vertebrate pests. We’re investigating how best to monitor and quantify threatened species and ecosystem recovery on the island in the wake of this eradication.
“This research will assist in decision making around island eradications globally.”
The research team will work closely with a wide range of stakeholders to fill knowledge gaps, facilitate sharing and learning from other island experiences, improve prioritisation and demonstrate strategies on how, where and when to invest in on-ground island management activities.
Salit and Justine recently ran a workshop as part of the Island Arks Symposium IV on Norfolk Island.

With other concerned conservation biologists, researchers from the Threatened Species Recovery Hub have developed a ‘blueprint’ for management responses to the 2019-20 wildfires. This report can be downloaded from our website.
The Threatened Species Recovery Hub of the National Environmental Science Program expresses our sympathy to everyone whose life has been impacted by these horrific fires, and acknowledges the heartbreak of families who have lost everything, including loved ones.
Many landscapes in Australia are fire-prone, and increasingly so. Altered fire regimes can have a serious negative impact on threatened plant species and ecological communities. A Threatened Species Recovery Hub project is working to better understand the effects of different fire regimes on threatened flora in order to improve fire management strategies and conservation outcomes.
Almost a quarter of Australia’s possums and gliders are listed as threatened under Australian environmental law, and many more are showing signs of decline. Dr Rochelle Steven from The University of Queensland believes people in the community can do a lot to support conservation, especially in urban areas.
The detection and monitoring of threatened species have been a strong area of research in the National Environmental Science Program and also the two national environmental research programs which preceded it. Hub Director Professor Brendan Wintle takes a look at what we’ve been achieving and why it is so important to the conservation of Australia’s threatened species.
