individuals. The main threats to the species are introduced mammalian predators, principally cats and rats, other threats are present from feral pigs collapsing burrows. The land on which tāiko were first rediscovered was privately owned by Manuel and Evelyn Tuanui, who in 1983 donated 1283 hectares of land to the government to protect the species, becoming the Tuku Nature Reserve. In a 2004 report, about 80 percent of tāiko breeding burrows were in this reserve. The Tuanui family were also founding members of the Chatham Island Taiko Trust, an organisation formed to promote taiko conservation work. A conservation strategy is in place on the island to translocate chicks to an area where the main threats have been removed called the Sweetwater Secure Breeding Site. Studies in other petrel species such as the Manx shearwater, wandering albatross, and Cory's shearwater, have shown that birds return to the site in which they fledged. In 2007, eight chicks were successfully translocated and fledged from the breeding site. There has also been a predator-proof fence built around a small area of land since 2006, 60 tāiko have been relocated to this area.
