Macquarie Island Pest Eradication Project
Tasmania Parks and Wildlife Service, TAS

Between 2007 and 2015 the Tasmania Parks and Wildlife Service undertook the world’s largest island eradication project to remove all rabbits, ship rats and mice from World Heritage-listed Macquarie Island.

Located in the Southern Ocean halfway between New Zealand and Antarctica and 1,500 km from Hobart, Macquarie Island presented numerous challenges in terms of logistics, weather and field operating conditions. Rabbits and rodents had enormous impacts on the fragile environment of Macquarie Island, causing massive loss of vegetation, increased erosion on the steep coastal slopes, and predation on the eggs and chicks of burrowing seabirds.

Funding from the Tasmanian and Australian governments of $24.6M, and a donation of $100,000 from WWF-Australia and Peregrine Adventures, allowed implementation of the plan to eradicate the three invasive mammal species on Macquarie Island.

Intensive planning from 2007 to 2010 was required to obtain all regulatory approvals and complete the complex operational planning and procurement aspects required. After an initial release of the Rabbit Calicivirus, four helicopters spread rodenticide bait in the winter of 2011 across the entire island. This successfully eradicated mice and rats and removed the majority of surviving rabbits. Hunting teams using specially trained dogs then covered the island intensively for the next two and a half years, searching for and removing the few rabbits that remained. In all, hunting teams covered 92,000 km to ensure no rabbits or rodents survived.

Recovery of vegetation has been dramatic and seabird populations are now re-establishing on the island.
