About Crooked Brook Marsh Preserve

Crooked Brook Marsh Preserve is an important wetland habitat in New Hampshire known for its rich biodiversity and excellent opportunities for birdwatching and nature observation.

Wilderness Landscape & Natural Heritage

Crooked Brook Marsh Preserve spans a substantial wetland area along Crooked Brook in Alstead, New Hampshire. This preserve protects a significant expanse of forested wetlands, marshes, and riparian ecosystems that contribute to the ecological integrity of the region. The area serves as crucial habitat for a variety of wildlife, including migratory birds, amphibians, and small mammals. Its wetlands support rare plant species and act as a water filtration system, maintaining water quality downstream. Historically, the site has been preserved to safeguard this rare habitat type within the state and to provide a quiet natural area for passive recreation. Visitors frequently come to Crooked Brook Marsh Preserve for hiking, birdwatching, and photography, especially in spring and fall migration seasons when waterfowl and songbirds are most active. The preserve has relatively low-impact, unmarked trails that wind through mixed hardwood and softwood forests adjacent to the marsh, offering peaceful walks and wildlife viewing opportunities. Despite its remote character, the preserve is appreciated by naturalists and local outdoor enthusiasts seeking to experience New Hampshire’s wetland environments. The preserve’s importance extends beyond recreation, playing a vital role in regional biodiversity conservation and watershed protection. Crooked Brook Marsh Preserve offers a quiet retreat away from developed areas with scenic views of marshland and watercourses, attracting both casual visitors and dedicated nature observers.
