Threatened Species & Island Conservation

Protecting biodiversity and island ecosystems

Island systems are amongst the most threatened globally. We work across a wide range of offshore islands with a focus on threat identification and mitigation for birds and other fauna. Ongoing work includes a long-term monitoring program (20+ yrs) for seabirds, shorebirds and migratory land birds at Ashmore Reef, Browse Island and Adele Island off north-western Australia. This includes major programs with industry and government partners that aim to address threatening processes (weeds, invasive invertebrates and rodents) and recover seabird and marine turtle colonies on Browse Island and at Ashmore Reef.

We also conduct research on a suite of threatened seabirds and land birds in the Norfolk Island group where our goal is to secure the future of these unique species. We are undertaking ecological research to inform island-wide restoration of Phillip Island (in the Norfolk Island group). Additional threatened species that we work closely with are the Vanuatu Petrel (Pterodroma occulta) in the Banks Group, Vanuatu, and the Beck’s Petrel (Pseudobulweria becki) in New Ireland. Very little is known about these elusive species and we aim to uncover information that will help inform conservation management.

Our experience with the management of invasive species on islands includes a control program for the invasive tropical fire ant at Ashmore Reef, a large-scale attempt to eradicate Polynesian Rats from Adele Island and targeted research that informs rodent management on Norfolk Island and Browse Island.

Islands we work on

Norfolk Island group

Our team have worked extensively on Norfolk Island with all five endemic songbirds, the Norfolk Island Morepork and invasive rodents. We have also spent much time on the nearby Phillip Island investigating seabird movement, giant centipede ecology and island restoration.

Browse Island

The work we do on Browse Island is closely paired with reserve management actions and aims to address key threatening processes on the island, primarily invasive rodents. Our research aims to promote the recovery of breeding seabird colonies and to inform future island restoration projects.

Cocos (Keeling) Islands

Our work on Pulu Keeling National Park, located in the Cocos (Keeling) Islands, is focussed on improving monitoring outcomes for a variety of seabird species. The island supports one of the world's largest breeding colonies of Red-footed Booby, a focal species for our research on the island.

Christmas Island

We have also been working on Christmas Island, using drones to monitor seabird colonies. Due to range restrictions, Great Frigatebirds and Christmas Island Frigatebirds now nest in mixed colonies across the island. We have used fine-scale aerial imagery to investigate niche partitioning between these species. We have also recently commenced work on the Christmas Island Hawk-Owl and Christmas Island Goshawk.

Ashmore Reef

Our work on Ashmore reef first began in the year 2000 and we have now published over 30 papers on this island system’s ecology, particularly the breeding seabirds. We hold long-term dataset on the biodiversity of seabirds and cetaceans in the area. This research has been critical in to inform the response to the 2009 Montara Oil Spill, and the ecological management of the Ashmore Reef Marine Park.

Vanua Lava

Our work here in the Banks Islands in northern Vanuatu is focussed on the Vanuatu Petrel, revealing ecological insights that contribute to Island management more broadly.

New Ireland

Our work in New Ireland is focussed on the enigmatic Beck’s Petrel. Here we aim to gather new ecological data to inform the conservation status and the conservation management of this species.

Great Barrier Islands

Our work on East Fairfax, Lady Elliot and Michaelmas Cay involves a long-term seabird monitoring program using drones and population counts. Our contributions are in partnership with the Department of Environment and Sustainability (DES). We also provide input to the scientific advisory group for Raine Island.
