The Year’s Biggest Marine Reserve Wins in 12 Stunning Photos

From Palau to Easter Island, a visual tour of the major gains in ocean conservation

2015 was a landmark year for ocean conservation. With the announcements of the Palau National Marine Sanctuary, an Easter Island Marine Park, the Pitcairn Islands Marine Reserve, and the Kermadec Ocean Sanctuary, more than 2.5 million square kilometers of additional ocean (about 965,000 square miles) will soon be fully protected. This will increase the total amount of ocean safeguarded at this level to 6.5 million square kilometers (2.5 million square miles).

Worldwide, about 2 percent of the ocean has been set aside as fully protected marine reserves; scientists recommend at least 30 percent. This oceans map shows where Pew’s Global Ocean Legacy campaign has worked, its progress to this point, and where its ongoing efforts are focused.  

See why these four wins are worth celebrating.

Palau Creates Earth’s 6th-Largest Marine Reserve

Palau President Tommy E. Remengesau Jr. signed the Palau National Marine Sanctuary Act on Oct. 28, protecting 80 percent of the island nation’s exclusive economic zone (EEZ)—a higher percentage of safeguarded waters than in any other country in the world. EEZs extend roughly 200 miles from a country’s coast.

Palau’s waters contain more than 700 species of coral—such as table coral, shown here—and 1,300 species of fish. Together, they contribute to the teeming seascapes surrounding this Pacific nation’s 250-plus islands.

Divers follow a humphead wrasse. Economists estimate that the scuba diving industry injects about $90 million a year into Palau’s economy. In fact, one study found that a single reef shark kept alive in Palau’s waters is worth US$1.9 million in tourism over its lifetime. (Video: “Palau’s Paradise.”)

Easter Island Makes History, Again

Several of Easter Island’s famous moai—giant, centuries-old statues—stand watch over Pacific waters from the Chilean territory. On Oct. 5, Chile’s president, Michelle Bachelet, pledged to work with the indigenous Rapa Nui community to create a fully protected marine park.

Spiny LobsterEduardo Sorensen

The largely unexplored waters around Easter Island (also known as Rapa Nui) contain areas of rare biodiversity and geological hot spots, including the only hydrothermal vents—cracks in the seafloor that spew volcanically heated water—in Chilean waters. Shown is the Easter Island spiny lobster.

The tipi tipi uri, or Easter Island butterflyfish, is one of 142 species found only in the waters surrounding Easter Island; 27 of these are threatened or endangered. (Video: Easter Island’s stunning sea life.)

Pitcairn Protections Break Record

On March 18, the British government announced plans to establish the Pitcairn Islands Marine Reserve in the waters surrounding this South Pacific territory. At roughly 3 ½ times the size of the United Kingdom, the newly protected area will be the world’s largest fully protected marine reserve

Pitcairn’s marine ecosystem includes the world’s deepest known living plant, a species of encrusting coralline alga found 382 meters (1,253 feet) below sea level.

Forty-Mile Reef—thought to be the world’s deepest and best-developed coral reef—will be protected by the Pitcairn reserve.

Enlarging the Protected Area Around the Kermadecs

Building on a smaller reserve established in 1990, New Zealand Prime Minister John Key announced plans Sept. 28 for a 620,000-square-kilometer (239,383-square-mile), fully protected ocean sanctuary in the waters surrounding the Kermadec Islands about 1,000 kilometers (620 miles) northeast of New Zealand’s North Island.


The South Pacific’s Kermadec region is home to more than 50 underwater volcanoes, which form part of the longest underwater volcanic arc on the planet.

Up to 6 million seabirds breed on the Kermadecs each year. Three of the world’s seven species of sea turtles also can be found there. (Video: The Kermedecs’ undersea wonders.)

Biomedical researchers are on the front lines of scientific innovation. From responding to global pandemics to pioneering lifesaving cancer treatments, these researchers push past scientific boundaries to solve pressing health challenges. For nearly 40 years, The Pew Charitable Trusts has supported more than 1,000 early-career biomedical scientists committed to this discovery.


Our Blue Planet–Protecting the Ocean

Episode 6

Quick View

Three-quarters of our planet is covered with water—and it’s this water that sustains life. But our liquid planet, home to half of the world’s known creatures and plants, is facing multiple threats, such as overfishing and commercial development. That’s why leading scientists say that 30 percent of our oceans should be protected. Host Dan LeDuc explores why this 30 percent data point is important with two people committed to safeguarding the oceans: native Hawaiian Sol Kaho’ohalahala, whose culture and livelihood depend on sustainable seas; and Matt Rand, who directs the Pew Bertarelli Ocean Legacy Project and has been working with people like Kaho’ohalahala since 2006 to keep our oceans healthy.
