Less than 1% of the original tallgrass prairie in Minnesota remains. Much of the remaining prairie and its plants and animals are threatened due to loss of habitat, with one of the primary threats being the invasion of aggressive, non-native trees. The Boy Scouts helped to reduce these stresses and restore the prairie through invasive species removal. Photo by Scott Glup/USFWS.
