Devils Tower National Monument was established through presidential proclamation to preserve and protect the geologic formation known as Devils Tower and the surrounding forests and meadows. Unfortunately, it is not always possible to maintain a completely natural ecosystem within this small 1347 acre monument. Many outside influences affect the plants, animals, and landscape at Devils Tower. Humans manipulate the environment for their own purposes; fires are suppressed; non-native plants and animals make their way into the area. The Resource Management staff at Devils Tower are involved in many projects to inventory, monitor, and allow natural systems to occur within the monument which maximize the health and diversity.
