Assabet River National Wildlife Refuge

Fish and Wildlife Service, Massachusetts.



Assabet River National Wildlife Refuge, located in the towns of Sudbury, Stow, Maynard and Hudson, and just 20 miles west of Boston. Assabet River is one of eight national wildlife refuges that comprise the Eastern Massachusetts National Wildlife Refuge Complex. Over time these lands were traditionally hunted and fished by Nipmuc Tribes, farmed by colonists, crossed by railroad and used for military training. This area was known as the Sudbury Training Annex, part of Fort Devens and the U.S. Army until 2000 when the U.S. Army transferred over 2,000 acres to the U.S. Fish and Wildlife Service, therefore establishing the refuge.  



Important habitat types on the refuge, such as freshwater wetlands, oak-pine forest, and shrubland are crucial in our management of migratory bird conservation. Wildlife that call Assabet River home include, but not limited to, waterfowl and wading birds, songbirds, raptors, American beaver, bobcat, white-tailed deer, and various reptiles and amphibians.
