About Mashomack Preserve

 

Mashomack Preserve spans over 2,000 acres on Shelter Island, located between the North and South Forks of Long Island, New York. Managed by The Nature Conservancy, it features a variety of ecosystems such as oak-pine forests, freshwater ponds, tidal creeks, and salt marshes. This diversity supports a wide range of flora and fauna, making it a popular destination for birdwatching, including sightings of herons, osprey, and occasionally migrating raptors. The preserve’s trails allow visitors to explore different natural habitats in a serene setting. Historically, the land was part of large private estates before being acquired for conservation purposes in the late 20th century to protect its unique coastal environment. Visitors can hike, bike, and canoe on designated trails and waterways, as well as enjoy wildlife viewing and photography opportunities. Notable landmarks include the historic Mashomack Pond and the maritime forest areas. The preserve’s relatively remote location on Shelter Island contributes to its peaceful atmosphere, offering a retreat from the busier nearby regions of Long Island. Mashomack is a key conservation area that helps maintain the ecological health of Shelter Island and serves as a critical sanctuary for native species.
