Wildlife and habitat

The primary purpose for which the Refuge was created is its "...particular value in carrying out the national migratory bird management program." The Refuge's interspersion of wetland, forested upland and old field habitats is ideally suited for this purpose. The Refuge supports a diverse mix of migratory birds including waterfowl, wading birds, raptors, shorebirds, passerines, as well as resident mammals, reptiles, amphibians, fish and invertebrates. The extensive and regionally significant wetlands occurring on and adjacent to the Oxbow Refuge, including their associated tributary drainages and headwaters, have been listed as a priority for protection under both the North American Waterfowl Management Plan and the Emergency Wetlands Resources Act of 1986. The portion of the Oxbow NWR south of Route 2 lies within the 12,900-acre Central

Friends group
