Wilderness Landscape & Natural Heritage
The Great Bay Estuary Preserve encompasses a complex estuarine ecosystem located primarily in southeastern New Hampshire and extending marginally into southern Maine. Covering more than 6,000 acres, it includes tidal salt marshes, mudflats, eelgrass beds, salt marsh peatlands, open water, and adjacent uplands, forming one of the largest estuaries in the northeastern United States. This estuary serves as a critical habitat for numerous migratory birds, fish, shellfish, and endangered species, such as the endangered Atlantic salmon and the piping plover. The preserve plays an important ecological role in filtering pollutants, buffering storm surges, and supporting commercial and recreational fisheries. Established and maintained through partnerships involving the Great Bay National Estuarine Research Reserve, The Nature Conservancy, and local conservation organizations, the area offers visitors access via numerous trails and water routes. Key recreation opportunities include paddling through the salt marsh channels, guided wildlife tours, birdwatching at sites like the Great Bay Discovery Center, and seasonal shellfishing. Notable landmarks within the preserve include the expansive salt marshes of Tucker Cove and the historic Mill Pond, used for freshwater inflow. Visitors are often drawn to the preserve’s combined natural beauty and educational resources, making it a popular destination for families, naturalists, and outdoor enthusiasts seeking accessible coastal experiences. The Great Bay Estuary Preserve remains a cornerstone for regional conservation efforts, fostering collaboration between scientists and citizens while offering hands-on learning about estuarine ecology and conservation.
