Union Slough National Wildlife Refuge
Union Slough National Wildlife Refuge was established in 1938 to provide a refuge and breeding ground for waterfowl and other migratory birds. The actual slough is all that remains of a pre-glacial riverbed, and its name is derived from the connection or "union" of two watersheds: the Blue Earth River of Minnesota and the East Fork of the Des Moines River. The terrain is nearly flat, allowing the flow of the water to be determined by the direction of the wind at times.
The refuge is on the eastern edge of the tallgrass prairie region of the Northern Great Plains an area known for its agriculture. This 3,334-acre refuge surrounded by a sea of corn and soybeans provides vital habitat for a variety of plants and animals dependent upon tallgrass prairie and wetland habitats.
Getting There . . .
Union Slough Refuge is roughly 2.5 hours southwest of Minneapolis and northwest of Des Moines.

The various types of land on the refuge require a variety of management methods. To provide nesting habitat for waterfowl and other upland species and to slow the effects of runoff and erosion, refuge staff are restoring native grassland species on areas of the refuge once used for agriculture. Mowing and controlled burning are some of the techniques used to control invasive plant species and to restore native species on the refuge.
Water levels are manipulated to approximate the water levels of the slough that existed before the arrival of humans. Through water level management, the refuge can support a healthy system of wetlands. This system of temporary, seasonal, and permanent wetlands is similar to that encountered by the first white settlers to northern Iowa.
