Grindstone Flat and Big Flat Exclosures, A 41-Year Record of Changes in Clearcut Aspen Communities

摘要

The role of deer and cattle in the failure of aspen stands to regenerate on Beaver Mountain in southern Utah was investigated by a series of exclosures constructed in 1934. Three-fourths of each exclosure was clearcut of aspen in 1934. Aspen reproduction, shrubs, and herbaceous understory were measured in 1937, 1942, 1949, and 1975. Implications of wildlife and livestock use on aspen reproduction are discussed.
