Hamlin Reservation’s gently rolling fields and marsh meadows – today home to bobolinks and small mammals – were once active farmland. A historic dike was created to connect Eagle Island with the mainland so livestock could graze the island’s pastures. Today the island is covered by a white pine, oak, and hickory forest. A short loop trail circles the island, revealing remnants of old stone walls that were built along the perimeter of the island. The Reservation’s extensive salt marsh, drained by the Labor-In-Vain Creek, provides habitat for a wide variety of fish and invertebrates and supports many wading birds, such as glossy ibis and snowy and American egrets. Hamlin Reservation represents one of the least disturbed parts of the entire 25,000-acre Great Marsh.
