History and Conservation

People had lived in the Saint Francis River valley for more than ten thousand years. North American Indian settlements in the Sherburne National Wildlife Refuge date back to around 1300. More recently, the area was settled under the Homestead Act during the 1870s .

Originally, the basin of the St. Francis River one of the richest game areas in Minnesota, where thanks to the large number of small lakes and flood plains near the river and the surrounding Vergation with wild rice and other wetland plants large amounts of wild ducks , muskrats , beavers and mink one had a good living. The surrounding high banks were habitat for elk , bison and gray wolves . By the middle of the 20th century, various influences had greatly reduced the value of the habitat for animals and plants. Wetlands were drained by drainage ditches built in the 1920s to increase the agricultural area. During the early 1940s, carp invaded the region's lakes and rivers. Their feeding behavior led to the existing vegetation being overturned, which was important for the abundance of game in the water. In addition, the original oak savannahs have been converted into agricultural areas or residential areas. In 1965 the Sherburne National Wildlife Refuge was established in an attempt to restore the original habitat for wildlife on the St. Francis River.
