Koyukuk National Wildlife Refuge

Koyukuk National Wildlife Refuge spans 3,500,000 acres in Alaska along the Koyukuk River floodplain, protecting an immense mosaic of wetlands, wooded lowlands, sloughs, streams, and shallow lakes reaching from the Yukon River toward the Purcell Mountains and Brooks Range foothills. It is a crucial northern wetland habitat for fish, beaver, Alaskan moose, breeding waterfowl, migratory songbirds, and raptors; in one nesting season, up to 100,000 ducks may be raised there. The refuge also includes major connected wetland and wilderness areas such as Kaiyuh Flats and Three-Day Slough, supports rich fish populations, and sustains caribou, wolves, bears, lynx, foxes, and marten.
