In March 2015, the United Kingdom declared the world's largest fully protected marine reserve in the remote waters surrounding the Pitcairn Islands in the South Pacific Ocean. The designation marks the first time any government has combined creation of a fully protected marine area with detailed plans for surveillance and enforcement that include use of the most up-to-date technology available. This approach sets a new standard for the comprehensive monitoring of protected areas. In 2013, The Pew Charitable Trusts and The National Geographic Society joined the local government, the Pitcairn Island Council, in submitting a proposal calling for creation of a marine reserve to protect these spectacular waters. The Pitcairn Islands Marine Reserve spans 834,334 square kilometres (322,138 square miles). Together with the Chagos Marine Reserve in the Indian Ocean, designated in 2010, the United Kingdom has created the world's two biggest fully protected marine areas, totalling 1,474,334 square kilometres (569,243 square miles). Through these actions, the United Kingdom—caretaker of the fifth-greatest amount of marine habitat of any country in the world—has established its place as a global leader in ocean conservation.
