About the Inventory

The Marine Protected Areas Inventory (MPA Inventory) is a comprehensive geospatial database designed to catalog and classify marine protected areas within U.S. waters. The Inventory contains information on over 1,700 sites and is the only such comprehensive dataset in the nation.

The MPA Inventory was developed with extensive input from state and federal MPA programs and drawn from other publically available data. The MPA Center is continually updating and verifying the Inventory data, so please contact us with any new site information, existing site clarifications or updated spatial boundary data.

MPA Inventory Applications

What can the MPA Inventory tell me? Download a quick guide on the MPA mapping tool for information on common questions the MPA Inventory and mapping tool can answer.

The database has various applications for marine management and conservation, but its primary purpose is to maintain baseline information on MPAs to the assist in the development of the National System of MPAs, as defined in Executive Order 13158. This information should not be used for regulatory purposes; please consult the Federal Register for the official record.

If you would like to propose the addition of an MPA to the MPA Inventory, please complete the form below and return to the MPA Inventory team.

Next Steps

The MPA Center is expanding the MPA Inventory to include site specific information on ecological and cultural resources as well as MPA management. These data are represented in 'Resource Groups' based loosely on the Coastal and Marine Ecological Classification System (CMECS) to ensure comparability between diverse sites from a wide geography.
