Threats to subantarctic teal
Auckland Island teal, Enderby Island
Causes of decline
Both species declined as a result of the impacts of introduced mammals. These mammals arrived with propel visiting the islands. Introduced predators such as cats and rats have eliminated teal from many areas of their former range with the island groups.
Predation
Accidental introduction of predators, such as rats, to teal habitats would result in the extinction of the Campbell Island teal and cause local extinctions of Auckland Island populations.
Disease
The isolation of the subantarctic islands means both species, the Auckland Island teal and Campbell Island teal, are vulnerable to the introduction of disease which would have a catastrophic effect.
