Tristan-Goughian BioProvince

Situated in the South Atlantic, this BioProvince (as defined by Armen Takhtajan) includes the islands of Tristan da Cunha, Gough, Inaccessible and Nightingale. These volcanic islands lie about 400 km east of the Mid-Atlantic Ridge, but their volcanic activity is unrelated to the activity associated with the Mid-Atlantic Ridge. Nightingale is the oldest in the archipelago at 18 million years old, while Inaccessible is around 5 million years ago, and Tristan da Cunha is relatively young at just 1 million years old.
