[2] The island is most famous for its Campbell teal, which was thought to have been extinct for more than 100 years until a small group was rediscovered there in 1975.
The Campbell teal conservation programme started in 1984 when four birds were transferred from Dent Island to the Pukaha / Mount Bruce National Wildlife Centre.
[3][4][5][6] In 1997, a census carried out on Dent Island showed that its Campbell teal population had declined to dangerous levels with only three birds being found.
However, the conservation and breeding has been very successful, and in recent years many teals have been reintroduced onto Campbell Island itself, where there is now a population of over a hundred.
