Kiribati: the world’s largest marine reserve

The Republic of Kiribati in the South Pacific has designated an enormous swath of Pacific atolls, coral reefs, and deep ocean to become one of the world’s largest marine reserves.

The Phoenix Islands Protected Area safeguards some of the planet’s most pristine coral reef ecosystems. The new marine park is the world’s third largest, topped only by Australia’s Great Barrier Reef and the Northwestern Hawaiian Islands.

The protected region spans some 73,800 square miles (184,700 square kilometers “a stretch of ocean twice the size of Portugal” and includes eight virtually uninhabited coral atolls.

The reserve is home to a panoply of marine life, including over 120 coral species and more than 500 types of fish—some found nowhere else.

Seabirds and turtles also frequent the region, which lies along key migration routes.

The park includes deep-ocean habitat found in no other marine reserve and protection extends even to seamounts on the ocean floor.
