Great Meadows National Wildlife Refuge is one of the eight refuges that comprise the Eastern Massachusetts National Wildlife Refuge Complex. The refuge is made up of several pieces of land with two main units- the Sudbury unit and the Concord unit. Visitors have the opportunity to explore a variety of riparian landscapes and habitats while enjoying numerous recreational activities like hiking, snow shoeing, fishing, hunting, and boating on the Sudbury and Concord Rivers.

Visit Us

National Wildlife Refuges offer us all a chance to unplug from the stresses of daily life and reconnect with our natural surroundings. 

Nearly 85% of the lands that Great Meadows NWR conserves are freshwater wetlands alongside the Sudbury and Concord Rivers. The Sudbury unit includes tranquil trails around wetlands and through woodlands and features a non-motorized boat launch on the Sudbury River. The Concord unit has excellent birding opportunities, and noted ornithologists consider this unit to be one of the best inland birding areas in the state. This site has a wildlife observational tower, observational platform and direct access to the Concord River. Please note: there is an entrance fee to access the Concord Unit.

      About Us

      Our History

      Historically, refuge lands were primarily inhabited by many groups of Indigenous peoples. In 1944, a local hunter donated over 200 acres to U.S. Fish and Wildlife Service, establishing the refuge's Concord unit. The Sudbury unit was established later as the Service began buying additional land in the area to preserve vulnerable freshwater wetlands along the river. 

      The goal of refuge management is to provide habitat for native fish and wildlife, especially migratory birds. The refuge’s wetlands, fields and woods provide great habitat for many species, including migratory birds, semi-aquatic mammals like beaver, white-tailed deer, small mammals, insects, amphibians, and reptiles.

      What We Do

      Wildlife conservation is at the heart of the National Wildlife Refuge System. It drives everything on U.S. Fish and Wildlife Service lands and waters managed within the Refuge System, from the purposes for which a national wildlife refuge national wildlife refuge

      Our Species

      The refuge provides important habitat for many species, and is an especially significant spot for migratory birds. Great Meadows NWR has a recorded bird list of over 220 species. Waterfowl including mallards, black ducks, wood ducks and blue-winged teal are common sights at the right time of year. The refuge also provides habitat for the largest genetically distinct populations of threatened Blanding’s turtle in the Northeast. The rivers, freshwater wetlands, forests and fields of the refuge are home to monarch butterflies and other pollinators, as well as reptiles like the northern water snake, turkeys, coyotes, and woodchucks.
