Management strategies for threatened species to maintain biodiversity
Island systems are amongst the most threatened globally. We work on a number of offshore islands with a focus on threat identification and mitigation for avian species and other vertebrate inhabitants. Ongoing work includes a long-term monitoring program for both shorebirds and breeding seabirds at Ashmore Reef, Browse Island and Adele Island off north-western Australia and ecological research on seabirds to inform conservation management on Norfolk Island in the Pacific Ocean. We also conduct research on a suite of threatened land birds on Norfolk Island where our goal is to secure the future of these unique species. 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. Our team are also in the planning stages of a restoration program at Browse Island that aims to address threatening processes (weeds, invasive invertebrates and rodents) and recover seabird and marine turtle colonies at this important site. There are clear synergies with our work on marine vertebrate biodiversity, a summary of which can be seen here.
