Global Ocean Legacy


In March 2015, the British government announced its intent to create the world’s largest fully protected marine reserve in the waters surrounding the Pitcairn Islands. A small U.K. overseas territory in the remote central South Pacific Ocean, Pitcairn has one of the largest exclusive economic zones in the world. Within these waters lies one of the best-preserved ecosystems—a complex community of hard and soft corals that are home to hundreds of species of fish, including two found nowhere else on Earth. Pew, on behalf of the Global Ocean Legacy campaign partners, is working with the British government and the Pitcairn Island community to implement the Pitcairn Islands Marine Reserve and protect this important marine habitat for generations to come.
