Graz- ing capacity for most of this kind of range land with rolling-to-steep slopes is from 2 to 3 acres per animal-unit month. The relative herbage production of each site class was estimated from yield measurements made in pastures 1, 2, and 3 during the period 1943-45 (table 4). The yield from the best site was almost nine times that from the poorest, and the differences between sites are evidence that the grazing capacity of foothill ra

The yield from the best site was almost nine times that from the poorest, and the differences between sites are evidence that the grazing capacity of foothill ranges is related more closely to the sites than to the total acreage of the range unit. Steep slopes were not well represented within the sampling areas, but though not precise the yields estimated for the steep-slope site class are considered indicative of average production on such sites. The differences in yield between north and south exposures were determined from observations extending over 10 years. On north
