Specially adapted large mammals such as bison, pronghorn, wapiti (elk), and wolves once lived on Iowa's prairies. Now, only whitetail deer and coyote remain in the area near the National Historic Site. Smaller mammals such as red fox, pocket gophers, mice, and moles still abound in the restored prairie. Big brown bats fly overhead in the night sky catching insects. Raccoons, opossum, eastern cottontail, and squirrels also enjoy the protection of the national historic site.
