United States National System of Marine Protected Areas

The National System of Marine Protected Areas of the United States is a national initiative designed to strengthen the protection of U.S. ocean, coastal, and Great Lakes resources through the coordination of existing marine protected areas (MPAs). The national system of MPAs consists of the group of MPA sites, networks, and systems established and managed by federal, state, territorial, tribal and/or local governments that collectively enhance conservation of the nation's marine heritage and represent its diverse ecosystems and resources. Although managed independently, national system MPAs work together at the regional and national levels to achieve common objectives for conserving the nation's important natural and cultural resources. The national system does not bring state, territorial or local sites under federal authority, nor does it restrict or change the management of any MPA.
