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.

The University of Melbourne and the Threatened Species Recovery Hub are offering opportunities for Indigenous students to do PhDs on research in conservation and management of biodiversity, and threatened species.
Translocation is a very important tool in the fight against plant extinctions. Knowing when to do translocations, how to do them and how to measure their success can be a complicated business, especially considering the huge range of threatened plants in Australia. So where do you find the answers? Luckily, they are now all in one place, in new guidelines that will be a game changer for plant translocation. Dr Lucy Commander lets us know what is on offer.
We are offering an honours project looking at feral cats in two national parks. The student will analyse spatial data to quantify and compare home range, habitat use, and activity times of feral cats at both sites, and interpret these data in terms of risks to threatened species at the sites (bridled nailtail wallabies, bilbies, and others), and ecology and control of invasive predators.
Fifteen tiny quoll pouch-young have been born to three female eastern quolls from a pioneer group of 20 animals released into Booderee National Park. In a big win for the reintroduction project, these are the first eastern quolls known to be born in the wild on the Australian mainland for more than 50 years.
Mouse-sized carnivorous marsupial the Endangered Kangaroo Island dunnart has only rarely been seen in the past 20 years. TSR Hub researcher Rosemary Hohnen is on the job working with local partners to develop better monitoring methods for the elusive species, and to evaluate the impact of feral cats on its persistence. Here she gives us a taste of the action, and despite the tiny size of the mammal there is a lot of heavy lifting…
