An initiative of Marine Conservation Institute

"The most accurate and widely accepted tally of all MPAs"

At the Fall 2017 Our Ocean conference in Malta, the Pristine Seas Initiative presented its Malta Declaration where was recognized as "the most accurate and widely accepted tally of all MPAs." The Malta Declaration emphasized the current overestimation of global marine protection and highlighted our work to withold unimplemented sites from MPA coverage numbers as a more transparent and accurate method of tallying accurate marine protection levels. The inclusion of MPAs that are designated but unimplemented overestimates current protections on the water where it counts. Because many implemented areas do not offer full protections, only 2% of the global ocean is strongly protected today. Dr. Sala also asserted that the term “MPA” is overused and that marine protected areas should include verifiable ocean protection. They called on nations to create, implement, and enforce real MPAs in their EEZs and on the high seas. As nations hopefully heed this powerful message, MPAtlas will continue showing “true” marine protection.

“If we are to get to 10% of the ocean protected by 2020, we need to implement what has been committed, enact what has been suggested, and create new fully protected areas.  We also call on nations of the world to accelerate the creation, implementation, and enforcement of genuine protected areas within their exclusive economic zones and in the high seas.”

How is the Atlas of Marine Protection different from the official World Database on Protected Areas?

The team at the Atlas of Marine Protection ( endeavors to track marine protection levels as commitments by countries to increase MPA coverage become due. Currently, many countries are working to reach 10% protection of their marine waters by 2020. Through our own third party research, we adjust the offical MPA numbers reported by the World Database on Protected Areas (WDPA) to better track strongly protected and fully implemented marine protected areas. We include newly proposed, committed, or designated areas within days of announcement, carefully tracking areas that are proposed or promised, areas that are legally designated but as of yet unimplemented on the water, and those areas that are fully implemented and in force on the water. The Atlas of Marine Protection numbers differ from official WDPA numbers but our numbers are based on the comprehensive numbers found at the WDPA (

Global Ocean Refuges are the gold standard for marine protection

The Global Ocean Refuge System (GLORES, pronounced "glories") is an initiative by Marine Conservation Institute designed to catalyze strong protection for 30% of the ecosystems in each marine biogeographic region of the world’s oceans by 2030. It is a strategic, science-based way to safeguard marine ecosystems and will enable humans to recover marine life for us and future generations.

In 2017, we announced our first Global Ocean Refuges: Papahānaumokuākea Marine National MonumentMalpelo Fauna and Flora Sanctuary, and Tubbataha Reefs Natural Park. Each is an exemplary marine protected area that safeguards rich and irreplaceable marine ecosystems.

How Much of Our Ocean is Protected?

Today, only 3.7% of the world’s oceans are protected in implemented and actively managed marine protected areas. Approximately half of that, or 2.0%, of the ocean is strongly protected in no-take marine reserves.

SeaStates 2017 Report

The United States risks falling behind in our efforts to protect our important ocean protections while the rest of the world races to meet global targets. Read more in our annual SeaStates report on US marine protection for 2017.

Why MPAs?


Marine protected areas are essential to safeguard biodiversity and to sustain vibrant seas in the face of increasing pressure from human caused threats.

How Much is Protected?

Today only 3.6% of the world’s oceans are protected in implemented and actively managed marine protected areas. Approximately half of that, or 2.0%, of the ocean is strongly protected in no-take marine reserves.
