      About Us

      Assabet River National Wildlife Refuge is one of eight national wildlife refuges that comprise the Eastern Massachusetts National Wildlife Refuge Complex and is home to the Complex headquarters building. The lands the refuge consists of were traditionally hunted and fished by Nipmuc Tribes, later farmed by colonists, then 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, establishing the refuge. 

      Important habitat types at the refuge, such as freshwater wetlands, oak-pine forest, and shrubland are crucial in our management of migratory bird conservation. Many wildlife call Assabet River home including numerous species of waterfowl and wading birds, songbirds, raptors, American beaver, bobcat, white-tailed deer, and various reptiles and amphibians.

      Our Species

      The refuge helps conserve and protect wildlife and habitats surrounding the Sudbury-Assabet-Concord Rivers watershed. Special bird species the refuge manages for include the eastern towhee, gray catbird, scarlet tanager, Baltimore oriole, American woodcock, willow flycatcher, and the eastern kingbird. The Massachusetts' threatened Blanding's turtle is another important species that is managed for on the refuge. Biologists are partnering with researchers to establish a larger, diverse population of Blanding's turtles at Assabet River NWR. Protecting this species' wetland habitats not only helps to enhance the population, but also supports the entire ecosystem, including wetland plants, invertebrates, reptiles, mammals, birds, and amphibians.
