INDICATOR: Land Conservation for Wildlife in the Detroit River International Wildlife Refuge

Map of the International Wildlife Refuge

The Detroit River International Wildlife Refuge began in 2001 with 304 acres that included Grassy Island and Mamajuda Shoal. Later that year Mud Island was donated to the Refuge by National Steel Corporation (now U.S. Steel Corporation). In 2002 the Refuge expanded to include Calf Island. In 2003 the Refuge signed its first cooperative management agreement with DTE Energy to add Lagoona Beach Unit at Fermi Power Plant and the Brancheau Unit in Monroe, Michigan. In 2004, a milestone year for the Refuge, Humbug Marsh (the last remaining mile of natural shoreline along the U.S. mainland of the Detroit River) was acquired by the U.S. Fish and Wildlife Service and protected in perpetuity as part of the Refuge. Also in 2004 the U.S. Army Corps of Engineers donated the Strong Unit in Monroe, Michigan. In 2005, cooperative management agreements were signed with Automotive Components Holdings for Eagle Island Marsh Unit and with University of Toledo for Gard Island. In 2006, the Refuge nearly doubled in size with the signing of a cooperative management agreement with The Nature Conservancy for Erie Marsh along the lower portion of western Lake Erie. In total, the Detroit River International Wildlife Refuge has grown from approximately 304 acres in 2001 to over 5,047 acres in 2007. The Comprehensive Conservation Plan for the Detroit River International Wildlife Refuge has set a land conservation target of 12,000 acres (i.e., the Service has identified 12,000 acres of marshes, wetlands, islands, shoals, and uplands that could potentially be conserved through acquisitions, easements, and cooperative agreements).
