Global Ocean Legacy



  • At 247,105 sq miles (640,000 sq kilometers), the Chagos Islands and surrounding waters cover an area larger than France and more than 60 times the size of Yellowstone National Park in the United States.
  • Chagos accounts for 32 percent of the world’s fully protected marine reserves.
  • The waters of Chagos host 220 known species of coral and more than 700 species of fish.
  • The Chagos Islands provide a safe haven for more than 175,000 pairs of breeding seabirds.

Global Ocean Legacy, a project of Pew and its partners, aims to establish a worldwide system of very large, highly protected marine reserves where fishing and other extractive activities are prohibited.

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. We also worked with the Blue Marine Foundation.
