Papahanaumokuakea Marine National Monument (PMNM)

The Papahānaumokuākea Marine National Monument is the single largest conservation area under the U.S. flag, and one of the largest marine conservation areas in the world. It encompasses 139,797 square miles of the Pacific Ocean (362,073 square kilometers) - an area larger than all the country's national parks combined.

Papahānaumokuākea was established by Presidential Proclamation 8031 on June 15, 2006 under the authority of the Antiquities Act (16 U.S.C. 431-433). The Monument was expressly created to protect an exceptional array of natural and cultural resources. On July 30, 2010 Papahānaumokuākea was inscribed as a mixed (natural and cultural) World Heritage Site by the delegates to the United Nations Educational, Scientific and Cultural Organization's (UNESCO) 34th World Heritage Convention in Brasilia Brazil (click here to learn more).
