About Us

Great Meadows National Wildlife Refuge, one of the eight refuges that make up the Eastern Massachusetts National Wildlife Refuge Complex, is broken into several units with two main units, Sudbury unit and Concord unit. Prior to colonization the land that Great Meadows is on was primarily inhabited by Indigenous peoples including, the Nipmuc, Pawtucket, Wampanoag and Susquehanna Tribes. The river meadows and plains were burned to provide cropland and pasture for game and the water provided fish for food and fertilizer. In 1944, a local hunter, Samuel Hoar, donated over 200 acres to U.S. Fish and Wildlife Service, establishing the refuge in Concord. The Sudbury unit, where the Eastern MA Complex Headquarters is located, was established later as the Service began buying additional land in the area’s wetlands.

Roughly 85% of the refuge is composed of valuable freshwater wetlands, alongside the Sudbury and Concord Rivers. The goal of refuge management is to provide habitat for native fish and wildlife, especially migratory birds and the Massachusetts threaten Blanding’s turtle. Exotic plant control is a major management tool at Great Meadows. The refuge’s wetlands, fields and woods provide great habitat for many species, including vast avian groups, white-tailed deer, beaver, muskrat, otter, small mammals, amphibians, and reptiles including many species of turtles.

Our Mission


The Eastern Massachusetts National Wildlife Refuge Complex will contribute to the mission of the Refuge System and support ecosystem–wide priority wildlife and natural communities. Management will maximize the diversity and abundance of fish and wildlife with emphasis on threatened and endangered species, migratory birds, and aquatic resources.

The Complex will have a well-funded and community supported acquisition program which contributes to wildlife conservation. The refuges will be well known nationally and appreciated in their communities. They will be seen as active partners in their communities, school systems, and environmental organizations which will result in high levels of support for the refuges.

The refuges will be a showcase for sound wildlife management techniques and will offer top-quality, compatible, wildlife dependent recreational activities. Refuges open to the public will provide staffed visitor contact facilities that are clean, attractive, and accessible, with effective environmental education and interpretation.

Refuge Purposes

Each unit of the National Wildlife Refuge System is established to serve a statutory purpose that targets the conservation of native species dependent on its lands and waters. All activities on those acres are reviewed for compatibility with this statutory purpose.
