A Tamatea/Dusky Sound restoration plan has been developed with the ambitious goals of eradicating pests, re-introducing missing species and filling biodiversity information gaps in the area.
The project area includes Breaksea Sound, Acheron Passage, Wet Jacket Arm, and Dusky Sound itself, including over 700 islands, including New Zealand’s fifth largest island, Resolution Island.
Our vision is for Dusky Sound to be one of the most intact ecosystems on Earth, and New Zealand's largest ‘bio bank’ – a source of endangered native species that can be sent to pest free locations throughout the country.
Why is it so special?
History: The area is rich in both Māori and European history. From traditional iwi stories, to Captain Cook's landing in 1773. Dusky was also the site of one of the world’s first conservation reserves and New Zealands first conservation ranger (Richard Henry) in the late 19th century.
Isolation: Dusky Sound’s geographical isolation has assisted it to remain one of the least modified parts of mainland New Zealand, with lush native bush cover and relatively few weeds. Many of Dusky Sound’s islands have never been invaded by the introduced pests that now plague the mainland.
Success: In its current state Dusky Sound is an outstanding conservation resource that has allowed many vulnerable native birds, skinks, geckos, invertebrates and freshwater species to survive. The area also includes two marine reserves, Taumoana/Five Fingers and Moana Uta /Wet Jacket Arm.
Dusky Sound is a pioneer for island sanctuary projects, with many islands having had pest animals removed or reduced to low numbers.
Resolution Island: Because of its large size (c21,000 ha) and possum and rat free status, Resolution Island has a critical role in the success of the entire restoration project. It is the site of a stoat and deer eradication programme, one of the most ambitious pest control programmes in the world.
In 2011 mohua were returned, the first of what is hoped will be a long line of endangered species to find security on this immense island. Resolution Island may also one day be home to populations of takahē and kākāpō.
Controlling pests on smaller islands adjacent to Resolution Island creates more secure habitat for our native species, and helps prevent pests using these smaller islands as ‘stepping stones’ to reinvasion.
Breaksea Island: This island was cleared of rats in 1988 and is now pest free. This was a world first for an island of its size. The many tactics and lessons learned formed the basis for similar pest eradication programmes globally. A wide range of species including tieke, mohua, the knobbled weevil and Fiordland skink have since been transferred to this pest free island paradise and are now thriving.
Anchor Island: This special island was declared pest free in 2005 and is now home to some of our most endangered birds, including one third of the world's kākāpō population. Get more information.
Pigeon Island: This island was declared pest free in 2007 and is a mohua and South Island robin translocation site. Get more information.
Indian Island: This island was declared pest free in 2012 but a rat was discovered in January 2016 and it is thought they are now breeding.
Long Island: Pest control has recently started on this island and an intensive trapping network is being established to help protect the outlying islands from reinvasion.
The Tamatea/Dusky Sound restoration plan is a 30 year plan with 54 objectives covering: vegetation and habitat mapping, pest animal and weed control, translocations, monitoring, advocacy for additional marine protection and filling information gaps relating to seabirds, mokomoko/lizards, pekapeka/bats, terrestrial invertebrates, fresh water fish, mapping, marine mammals and fragile marine encrusting organisms.
