Multiple-use of rangeland is defined as the use of the land for more than one product or service. Implicit is that the land has multiple resources and that damage will not occur. For public-lands, multiple-use also implies for all the people. Many uses and values are largely indirect and socially determined. Multiple-use of public-lands has been public policy by law for many decades. In addition to biological production, multiple-use has elements of planning, politics, law, economics, sociology, and an explicit commitment to public involvement in decision making (Behan 1981).
