loam range site is similar to the sagebrush type. Associated with the deteriorated range • <br />condition is the high density of shrubs which occur on the site at the expense of the <br />herbaceous component. According to SCS range site descriptions and analysis of the <br />baseline vegetation data, shrub densities on the site are estimated to be higher than <br />optimum. These densities may be two to four times higher than the allowable amounts for <br />optimum range condition. Additionally, the northern portion of the permit area was burned <br />in the last 10 to 20 years which has encouraged extensive suckering in the mixed brush <br />type and an increase in mountain snorvberry in the sagebrush type (see Tab 10, Appendix <br />10-9). Aspen stands have also been affected by livestock grazing, particularly sheep <br />grazing. Many of the aspen stands in the permit area have somewhat depaupera to <br />understory vegetation and a distinct lack of regeneration. Existing stands are dominated <br />by mature and decadent trees. These observations are consistent with those in other areas <br />of the west (DeByle and Winokur, 1985). <br />While diminished range condition can be attributed to livestock grazing, it is further <br />compounded by the ecological characteristics of the woody plant communities and the <br />livestock and wildlife utilization patterns occurring in these communities. The woody <br />component in these communities readily increases when the herbaceous component is reduced • <br />in vigor or eliminated. <br />Cattle and sheep are not carried on the permit area during the winter months, thus <br />eliminating any winter browsing of woody species by livestock. Livestock grazing begins <br />in late May or early June. During the summer months, both cattle and sheep center their <br />foraging preferences on the more nutritious and palatable herbaceous species. While some <br />browsing of the woody species by livestock does occur during the summer, it is generally <br />limited because of the availability of succulent and more palatable species. In all, the <br />woody component is favored in these native stands. <br />In addition to livestock grazing, wildlife data for the permit area (see Tab 11, Wildlife <br />Survey) indicates that utilization of browse by big game is not excessive. The highest <br />use of browse by big game is expected to occur during the winter months. During the <br />summer months, use of browse will drop and big game will concentrate on the more <br />nutritious and palatable herbaceous species. Again, the woody component may be favored. <br />The apparent light use of browse by big game and livestock, coupled with the ability of <br />the woody species to increase under livestock grazing, has resulted in higher woody plant <br />2 <br />
