Using the Refuge
The Assabet River National Wildlife Refuge is one of the nation's newest wildlife refuges. The refuge is located approximately 20 miles west of Boston in portions of the towns of Hudson, Maynard, Stow and Sudbury. It is owned by the U.S. Fish and Wildlife Service and administered by the Eastern Massachusetts National Wildlife Refuge Complex Office located in the Great Meadows NWR, 73 Weir Hill Road Sudbury.
The Fish and Wildlife Service's information about the refuge can be found here: Assabet River NWR. Information about all the National Wildlife Refuges in Eastern Massachusetts cab be found here: Eastern Massachusetts NWR.
The US Fish & Wildlife Service administers and manages the National Wildlife Refuge System (NWR). The National Wildlife Refuge System, is the world's premier system of public lands and waters set aside to conserve America's fish, wildlife and plants. Since President Theodore Roosevelt designated Florida's Pelican Island as the first wildlife refuge in 1903, the System has grown to more than 150 million acres, 550 national wildlife refuges and other units of the Refuge System, plus 37 wetland management districts. Refuges offer a wide variety of recreational opportunities, and many have visitor centers, wildlife trails, and environmental education programs. Nationwide, over 34 million visitors annually hunt, fish, observe and photograph wildlife, or participate in interpretive activities on national wildlife refuges. For more on the refuge system, see www.fws.gov/refuges/.
The Assabet River NWR
The Assabet River refuge comprises over 2,333 acres of varied woodland, wetland, fields, ponds and streams, with historical and archaeological sites. It is divided into a 1,900-acre northern section, a 300-acre southern section, and 91 acres scattered along the Assabet River in Stow. The terrain is primarily flat but includes some prominent hills; elevations range from 170 feet near the river to 320 feet on Walnut Hill. Seventy percent of the refuge is forested with pine, oak and maple. There are over 470 acres of diverse wetland habitat including an Atlantic white cedar swamp. This jewel is connected to about 1,000 acres of other diverse protected space.
To date, biological surveys have identified over 650 plant species, 135 bird species, 25 mammals, 17 reptile species and 19 species of fish. More details on the species and ecology of the refuge can be found in the Refuge's comprehensive conservation plan (CCP) available at AssabetFinalCCP.pdf.
Access to the refuge is through the main entrance off Hudson Road in Sudbury and from the north entrance on White Pond Road in Stow. See here for directions.Assabet River NWR Boundary Map

The Eastern Massachusetts NWR Complex
The Assabet River National Wildlife Refuge is part of a larger complex of refuges in Eastern Massachusetts.
- The Eastern Massachusetts NWR Complex is part of some 19 communities - Assabet River NWR in Sudbury, Stow, Maynard and Hudson; Great Meadows NWR in Sudbury, Wayland, Lincoln, Concord, Carlisle, Bedford and Billerica; Mashpee NWR in Mashpee and Falmouth; Massasoit NWR in Plymouth; Monomoy NWR in Chatham; Nantucket NWR in Nantucket; Nomans Land Island NWR off Martha's Vineyard in Chilmark; Oxbow NWR in Harvard, Ayer and Shirley.
- In our neighborhood 20 - 35 miles west and north west of Boston we have three NWRs Great Meadows, Assabet River and Oxbow. They total over 7,500 acres (Great Meadows 3,600 acres, Assabet River 2,300 acres and Oxbow 1,667 acres).
- The 29 mile stretch of the Sudbury River flowing through Great Meadows NWR and Assabet and Concord Rivers in out vicinity are designated as "National Wild and Scenic River" These rivers are recognized for their outstanding ecology, history, scenery, recreation values, and place in American literature. The rivers are managed by the National Park Service in cooperation with the SuAsCo River Stewardship Council, which includes members from local towns, state government, and advocacy groups.
- In some of our communities the NWRs form a large proportion of towns lands - Assabet River NWR consists of large parts of the town of Maynard and Stow. In Sudbury, two NWRs Assabet River and Great Meadows take up a large proportion of town lands. In addition, the US Fish and Wildlife HQ in Eastern MA is located on Weir Hill, Great Meadows on Sudbury town land as well as the new Visitor center on Hudson Road. The Friends have prepared a series of maps that can be viewed on our website.
