Description: The effects of non-grazing on Ahwahnee coarse sandy loam were studied at the San Joaquin Experimental Range in central California. An exclosure, on which there had been no livestock grazing for 34 years, had a lower surface bulk density and lower acidity than an adjacent range that had been grazed. Bulk density averaged 1.08 gm./cc. on the ungrazed range, and 1.43 gm./cc. on the grazed range. The pH values were 6.15 for the ungrazed area, and 5.65 for the grazed area.

Key Words: livestock influences, soil compaction, central Sierra Nevada ecosystems, Ahwahnee coarse sandy loans, soil pH, gophers, soil density
