Big Stone National Wildlife Refuge

Ortonville, Minnesota


Big Stone National Wildlife Refuge is part of the Big Stone Lake-Whetstone River Flood control project. The U.S. Army Corps of Engineers transferred lands to the U.S. Fish and Wildlife Service, establishing the refuge in 1975. The refuge now encompasses 11,275 acres of the Minnesota River valley in Western Minnesota. A unique visual and geographical feature is the red lichen-covered granite outcrops for which the refuge was named.

Big Stone is primarily a grassland system with an interesting prairie-floodplain forest transition. Wildlife diversity is sustained by the variety of habitat types available, including native prairie, seeded grasses, wetlands, wetlands, wet meadows, floodplain forests, granite outcrops, wood lots, agricultural food plots, and various successional stages of trees and brush along sub-irrigated pool edges.
