The Chagos Archipelago and its surrounding waters are one of the most remote and unspoiled marine areas remaining on Earth.
Located in the middle of the Indian Ocean (PDF), Chagos is comprised of 55 islands and vast coral reefs. The waters surrounding these islands are some of the world’s healthiest. They serve as a refuge and breeding ground for large, critically important marine species such as sharks, dolphins, and green and hawksbill turtles.
The waters of the Chagos contain up to half of the healthy reefs in the Indian Ocean, making them one of the most ecologically sound reef systems on the planet. Teeming with life and functioning as an important nursery for fish and corals, they enrich and replenish the whole ocean with the ecological goods and services on which millions of people rely.
Through the Chagos Environment Network’s Protect Chagos campaign, Global Ocean Legacy is collaborating with eight leading conservation and scientific organizations to protect the rich biodiversity of the Chagos Islands and its surrounding waters.
