In 2017, after Hurricane Irma devastated the northeastern Caribbean and Florida Keys, the storm took aim at Marco Island, along Florida’s southwestern coast. Although the area braced for the worst, coastal wetlands, including those in the nearby Rookery Bay National Estuarine Research Reserve, blunted the hurricane’s forces and reduced the toll on Marco Island and mainland communities.
“We’ve seen it here in south Florida, the importance of forests and wetlands related to storm surge and hurricane protection,” Robert R. Twilley, executive director of Louisiana Sea Grant and a Louisiana State University professor, told PBS in a documentary about Rookery Bay. Twilley’s doctoral dissertation focused on the reserve. “They can knock down waves, they can protect shorelines from erosion, they can protect housing behind the trees.”
Rookery Bay is one of 29 estuaries in 24 states in the National Estuarine Research Reserve System (NERRS). Estuaries are vibrant, but vulnerable, areas along the coasts where freshwater flowing from rivers and streams mixes with saltwater from the ocean and bays. The mangroves, salt marsh, seagrass, and upland areas found in and around estuaries buffer developed areas from storms and provide habitat for a diversity of wildlife, including fish, shellfish, and seabirds. Together, these habitats and animals define and sustain much of the country’s coastal and Great Lakes regions.
Congress established NERRS in the early 1970s as part of the Coastal Zone Management Act, which promotes and relies on strong federal-state partnerships to balance shoreline development and conservation, while fully considering the “ecological, cultural, historic, and esthetic values” of these unique areas.
NERRS guidelines for implementing the program call for reserve sites across 29 distinct biogeographical subregions along the coasts and Great Lakes. Today, 20 of those subregions have at least one site, and some have multiple. The areas range from less than one square mile, such as Old Woman Creek in Ohio, to 581 square miles, in Kachemak Bay, Alaska. Together they cover more than 2,000 square miles of coastal habitat.
The 2017-22 NERRS strategic plan calls for the reserve system to expand to ensure that varied estuarine types are part of the system.
The process of establishing a NERRS site begins when a state governor submits a letter of interest to the National Oceanic and Atmospheric Administration (NOAA). If NOAA determines it can accept a new site in the system, it provides up to $100,000 in matching federal funds to help the state identify a site and develop a detailed management plan through a public process.
Once the secretary of commerce—who oversees NOAA—designates a reserve, it generally fulfills five missions:
At the same time, each NERRS reserve site has unique characteristics, and their managers have leeway to focus on locally relevant issues. And visitors to reserves can engage in recreational activities, such as fishing, kayaking, boating, bird-watching, hunting, hiking, and swimming.
The Pew Charitable Trusts recognizes the value NERRS offers to our nation’s coastal areas, which is why we support the program’s goal of expanding this vital system to help ensure that it represents the broad biodiversity of America’s coastal estuaries.
