Biodiversity
The British Overseas Territories have more biodiversity than the entire UK mainland. There are at least 180 endemic plant species in the overseas territories as opposed to only 12 on the UK mainland. Responsibility for protection of biodiversity and meeting obligations under international environmental conventions is shared between the UK Government and the local governments of the territories.
Two areas, Henderson Island in the Pitcairn Islands as well as the Gough and Inaccessible Islands of Tristan Da Cunha are listed as UNESCO World Heritage Sites, and two other territories, the Turks and Caicos Islands, and Saint Helena are on the United Kingdom's tentative list for future UNESCO World Heritage Sites.
The three regions of biodiversity hotspots situated in the British Overseas Territories are the Caribbean Islands, the Mediterranean Basin and the Oceania ecozone in the Pacific.
