Daniel Webster Wildlife Sanctuary in Marshfield, Massachusetts, protects 507 acres of coastal grassland, swamp, pond, river, and wet panne within a larger open landscape exceeding 1,000 acres. Much of the site was reshaped by people, especially after an 1872 dike created reclaimed farmland and triggered Marshfield’s “Dike Feud” between fishermen and farmers. The land later served as a substantial dairy farm assembled by Edward Dwyer before local residents campaigned to save it as open space. Mass Audubon acquired it in 1984. Today it is valued for public access, varied habitats, and abundant wildlife, especially grassland birds, purple martins, and many migrating species.
