Conserving Chagos Archipelago
Chagos is an archipelago of 55 tiny islands in the central Indian Ocean containing some of the most vibrant coral reefs, diverse marine life and cleanest sea water in the world. Amidst the serious threats to reefs around the globe, Chagos is a rare haven for marine biodiversity.
In response to the action of ZSL and partners, the British Government designated Chagos a no-take marine protected area (MPA) in 2010. It is now world's largest MPA at 640,000 km2, a landmark contribution to marine conservation. ZSL scientists and conservationists continue to work studying and protecting Chagos' biodiversity.

The World's Largest MPA
Over 275,000 people called on the UK government to establish the Chagos region as a protected area in 2010. This decision was one of the most significant ways the UK could contribute to global conservation.
ZSL was amongst organisations that contributed the vital science and support to make this decision happen.
Chagos Gallery and Blog
Take a look at some stunning images of the Archipelago in our Chagos Expedition gallery, and explore the many coral species that are central to the Chagos ecosystem in our Chagos coral collection gallery .
Join a multitude of scientists out in Chagos, telling their story via the Expedition Blog (English and Creole)
Connect Chagos: People and Wildlife
As part of ZSL’s commitment to global and local conservation capacity building, a multi-phase project to build environmental skills and awareness within the Chagossian community in the UK and overseas has begun. Find out more about Connect Chagos
As part of Chagos Conservation Trust's ongoing work, ZSL scientists and conservationists join expeditions to study the reefs, islands and now pelagic zone. This vital work ensures that the reefs remain healthy, and explores how best to manage the MPA.We also work with Chagossian communities providing studentships to educate new conservationists.
Open Ocean Monitoring
ZSL are part of a team of scientists using the latest video, satellite and tagging technology to develop new ways to monitor pelagic sharks and tuna, as well as validating the effects of MPAs for highly mobile species.
Find out how and where the team are doing this.
