Missisquoi National Wildlife Refuge is a protected wetland landscape in northwestern Vermont along Lake Champlain and Missisquoi Bay, near the Canadian border. Established on February 4, 1943, it is Vermont’s only national wildlife refuge entirely within the state and has grown from 1,582 acres to 7,232 acres. Its marshes, floodplain forest, bog, shrubland, grassland, and managed wetlands provide vital habitat for migratory birds and native wildlife. Recognized in 2013 as a Ramsar Wetland of International Importance, it includes Maquam Bog, Shad Island’s heron rookery, and habitat for thousands of ducks, endangered black terns, nesting ospreys, spiny softshell turtles, and other wildlife.
