Dent Island, New Zealand
From Wikipedia, the free encyclopedia
Dent Island is a sub-Antarctic 26 ha rock stack, lying 3 km west of Campbell Island and belonging to the Campbell Island group. Dent Island is located at . The Campbell Island Teal whose main habitat had been on Campbell Island was thought to be extinct for more than 100 years until a small group was rediscovered in 1975 (or 1972) on Dent Island, which was still free of predators, especially rats, which had been introduced to Campbell Island, leading to the extinction of the Campbell Island Teal there. The suitable habitat on Dent Island is much more limited than its 23/26 hectare area, because a large area of the island is bare rock. The Campbell Island Teal conservation programme started in 1984 when 4 birds were transferred from Dent Island to the Mount Bruce Wildlife Centre. In 1997, a census carried out on Dent Island showed that the Campbell Island teal population had declined to dangerous levels with only three birds being found.
