<br />Exhibit I/J Soils and Vegetation (continued) <br />Drainuge Fringe <br />This community exists along the transition zone between the drainage community and the Flat <br />pasture which comprises the majority of the permit area. Slopes for this community are from 5°ro to <br />20%. The fringe community consists of patchy greasewood and prickly pear cactus and some cool <br />season grasses. This community comprises only a few percent of the total permit area since much <br />of this community was avoided by avoiding the unnamed drainage in the permit area. <br />Flar Pasture Communrry <br />This community comprises 90-95% of the permit area and is the primary community to be <br />• disturbed by the operation. As is seen from the SCS site investigation, the flat area of the terrace to <br />be mined consists of primarily wheatgrasses, brome, cheatgrass (an annual), junegrass, ricegrass <br />and other native perennials. Biennial and perennial leguminous forbs such as alfalfa and yellow <br />sweetclover were also found in this community. Many weeds also exist, such as Canada thistle, <br />musk thistle, field bindweed and others. Although the SCS described the overall cover of the field <br />in the permit area as 25%, no breakdown of the total for annuals and weeds was given. From other <br />site investigations, it is estimated that the weedlannual portion of the total cover is 10-20% of the <br />25% cover. Since the site has not been imgated in the last few years, many weeds have entered the <br />site. <br />According to the soil survey data for the Mussel loam, typical productivity in a dryland pasture of <br />this type is approximately 800 Ibs dry vegetation per acre. This is consistent with site observations. <br />• <br />Carol Ann Perrrut CDMG Application 51 <br />
