Wildlife and Habitat

Remnants of the once vast tallgrass prairie are still found on hillsides, around wetlands, and on small isolated tracts on the Refuge.

Rich bird and animal life associated with the many lakes and marshes made the Lake Tewaukon area a heavily used hunting and living site for Paleo-Indians.

Management Activities
Before Euro-American settlement, prairie fires and bison were common on the prairie. Today, prescribed fire and short-term grazing are used to maintain prairie grasses and wildflowers, reduce and control non-native plants, and slow the invasion of grasslands by shrubs and trees. Keeping grasslands healthy is important for ground-nesting birds, grassland butterflies, and other prairie wildlife.

Water levels are manipulated in 38 wetlands along the Wild Rice River. These wetlands provide nesting, feeding, and resting habitat for waterfowl, shorebirds, and other wetland species.
