Popis: Approximately 46 million acres or 88 per cent of the land area of the state of Utah has been classified by Reuss and Blanch (1951) as "range land open for grazing." Although some of this area cannot be grazed because of inaccessibility, lack of water, poison plants, and similar factors, it is estimated that some 40 million acres or 78 per cent of the total land area is available for grazing. Most of this grazing land is federally owned (73 per cent), while only 22 per cent is privately held, and 5 per cent is state owned.
