- The refuge is located in a transition zone between flat, tallgrass prairie on the west and north, and a rolling hardwood forest - lake region to the east and south. It is in the migratory corridor of the Eastern prairie pothole population of Canada geese.
The refuge began restoration of wetlands and uplands in 1991. When completed refuge acreage should encompass almost 6000 acres of prairie wetland ecosystem and will support 219 species of migratory and nesting birds. Prior to settlement, the area teamed with waterfowl, prairie chickens, bison, wolves and other prairie wildlife. The station's objective is to restore/enhance 3,000 acres of wetlands and 2,250 acres of upland grass.
The Hamden Slough National Wildlife Refuge is located near Audubon, MN.
