British Indian Ocean Territory (BIOT)*

The BIOT, also known as the Chagos archipelago is one of the world’s best preserved tropical island systems and the best preserved in the central Indian Ocean.

These islands provide sanctuary for a multitude of species of seabirds. The islands are home to 10 Important Bird Areas (IBA) recognized by BirdLife International, including Barton Point Reserve in Diego Garcia, which is home to one of the world’s largest populations of Red-footed Boobies (Sula sula).

The well-preserved beaches of the Chagos islands provide ideal nesting conditions for two species of marine turtles. The crystal clear waters of the archipelago host over 220 species of coral spread out over 25,000 km² of well-protected reefs, as well as several species of whales, dolphins and sharks. Read more
