Report of the 1965 study commissioned by the Secretary of the Interior Morris Udall and completed by the Bureau of Outdoor Recreation (U.S. Department of the Interior). The report was a response to President Lyndon Johnson's "Natural Beauty Message" of February 8, 1965, in which he called for development and protection of a balanced system of trails—in the nation's metropolitan areas as well as in the countryside—in cooperation with State and local governments and private interests. Johnson called for such a trail system to help protect and enhance the total quality of the outdoor environment as well as to provide much needed opportunities for healthy outdoor recreation. This report helped provide a framework for the creation of the the National Trails System Act of 1968.
