According to the Multiple Use and Sustained Yield Act of 1960 (P.L. 86-517, June 12, 1960), as amended, multiple use of the national forests means the "harmonious and coordinated management of the various resources, each with the other, without impairment of the productivity of the land, with consideration being given to the relative values of the various resources, and not necessarily the combination of uses that will give the greatest dollar return or the greatest unit output." Multiple use implies a sustained yield of outdoor recreation, range, timber, watershed, and wildlife and fish values.
