National Estuarine Research Reserve System

The National Estuarine Research Reserve System (NERRS) is a national network of 30 estuarine reserves located in 23 states and Puerto Rico.


The mission of the NERRS is to practice and promote stewardship of coasts and estuaries through innovative research, education, and training using a place-based system of protected areas.

Established by the Coastal Zone Management Act of 1972, the Reserve System represents a unique partnership between NOAA and the coastal states. NOAA's Office for Coastal Management administers the program by providing guidance, coordination, technical assistance, and funding, and state or academic partners manage reserve resources, implement programs locally, and provide funds to match the federal investment.
