The commercial forests on Indian reservations within the United States cover approximately 6,500,000 acres. Over 5,000,000 acres may be classed as woodland because of a growth thereon of pinion, juniper and other non-commercial species. Nearly 40,000,000 acres are classed as being primarily grazing lands. While the amount of forest and grazing areas comprises but a small percentage of the lands of such classification in the nation, such land is o£ great economic importance and forms a substantial portion of the total area within such States as Arizona, New Mexico, Oklahoma and South Dakota.
