The National Estuarine Research Reserve System (NERRS) is a network of protected estuaries and other habitats in coastal and Great Lakes states and territories. Estuaries are vibrant but vulnerable areas where freshwater flowing from rivers and streams mixes with saltwater from the ocean. Although the Great Lakes are exclusively freshwater, their coasts share many characteristics of estuary ecosystems.

The freshwater and salt marshes, seagrass, mangroves, vernal pools, upland forests, and riverine islands in these reserves provide shelter and food for fish, shellfish, and birds; buffer developed areas from storms and sea level rise; define coastal communities; and support recreation and resource-based economies.

Created by Congress in the early 1970s as part of the Coastal Zone Management Act (CZMA), the NERRS supports research and stewardship of U.S. estuaries and strong collaboration among federal and state officials, academics, nongovernmental organizations, and other individuals and entities invested in healthy coasts. Each reserve is a partnership between the National Oceanic and Atmospheric Administration, which provides funding, national guidance, and technical assistance, and a state- or territorial-based entity, such as an agency or university, which is responsible for the day-to-day management of the site, with input from the local community.

The CZMA guidelines call for at least one reserve in each of 29 distinct biogeographical subregions. Pew is working with scientists, allied organizations, and national, state, and local officials to strategically expand the network.
