Seney National Wildlife Refuge in Michigan’s Upper Peninsula encompasses 95,212 acres of marsh, pools, bog, and forest formed from the former Great Manistique Swamp. Established in 1935 after failed drainage and farming schemes, it was reshaped in the 1930s by Civilian Conservation Corps crews into a managed wetland for wildlife habitat. More than 200 bird species live here, and its early Canada goose program helped restore a species then in sharp decline across North America. The refuge also includes the 25,150-acre Seney Wilderness and Strangmoor Bog, an exceptional sub-arctic patterned bog, and remains both a sanctuary and an active conservation center.
