Chagos Archipelago

Chagos coral reef

Located 500km south of the Maldives, Chagos – also known as the British Indian Ocean Territory (BIOT) - is an archipelago of 55 tiny islands in the central Indian Ocean which are surrounded by some of the most vibrant coral reefs, diverse marine life and cleanest water in the world.

Why we are there

The tropical coral reefs and islands of the Chagos Archipelago cover an area of approximately 19,000km2 in the BIOT. It has a huge diversity of marine and terrestrial species, with some of the most pristine coral reefs in the world and eight times more reef fish than anywhere else in the Indian Ocean. This incredible diversity, some of which is unique to Chagos, is still under pressure from threats such as climate change and illegal exploitation.

The world's largest no-take MPA

Over 275,000 people and a number of NGO's called on the UK Government to establish the territorial waters of the Chagos islands as a Marine Protected Area (MPA) in 2010. ZSL was amongst the organisations that contibuted to the science case for the creation of the reserve and that helped ensure its establishment. It is now the world's largest no-take Marine Reserve at 640,000 km2,an area twice the size of the UK. This decision was one of the most significant ways the UK could make a landmark contribute to global marine conservation.  

Scientific expeditions

As part of the ongoing work of marine science researchers, ZSL scientists and conservationists join expeditions to study the reefs and islands of the Chagos Archipelago. This vital work increases our understanding of this little-studied part of the world and ensures that the associated coastal and terrestrial ecosystems are managed effectively and remain healthy. 

Open ocean monitoring

More recently ZSL has been involved with open-ocean and deep sea monitoring of the waters surrounding the Chagos Archipelago. Using state of the art underwater cameras and tagging technology, presence and movement of top ocean predators is being documented for the first time.

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 is now in its third year.

Key species

Coral 

There are at least 220 species of coral on the reefs of the Chagos Archipelago, including the Chagos brain coral (Ctenella chagius), a species endemic to these waters. Corals not only created the tiny atoll islands of the Archipelago but thick strands of branching species continue to protect them from waves and storm damage.

Sharks & Rays

The Chagos Archipelago supports a diverse array of sharks and rays from coastal reef sharks to pelagic species such as the Shortfin Mako, Blue and Oceanic Whitetip sharks which patrol the open-waters. Chagos is also home to majestic animals such as reef manta rays and whale sharks. 

Tuna

Prior to the MPA's establishment, tuna were commercially fished in the area. The main species targeted were the yellowfin, bigeye and skipjack tunas but a number of other species are also known to inhabit the rich Chagossian waters including albacore tuna, dogtooth tuna and various species of mackerel.

People involved

ZSL’s Heather Koldewey manages the Chagos project overall, with Matthew Gollock leading on the pelagic fish studies and co-ordination from Kirsty Richards.

David Curnick is a PhD researcher at ZSL and University College London investigating the role of large marine protected areas as a conservation strategy for pelagic tunas and sharks.

Rudy Pothin, Kirsty Richards and Amdeep Sanghera are co-ordinating the Connect Chagos community outreach programme.
