What is the minimum necessary philosophy behind administrative activities?

In protecting wilderness character and resources and in managing wilderness use in accordance with the Wilderness Act, the managing agencies adhere closely to the "minimum requirements" or "minimum tool" concept. Minimum means the least possible and a requirement is a necessity. So, the minimum requirements concept is to first determines if any management action is necessary in wilderness, and then determine how to accomplish the action using the least amount (if any) of an otherwise prohibited use, such as the use of chainsaws or motorized vehicles. Forest Service Policy, for example, requires, with few exceptions, the use of traditional tools, such as cross-cut saws, and that employees acquire and maintain skills to travel and work in wilderness.
