The type of vegetation is <br />important because herbaceous cover, grasses, will protect the <br />soil better than trees or shrubs at the same vegetative cover <br />levels. The enclosed table, reproduced from the EPA (1977), shows <br />how the "C" factor is related to the vegetation. <br />According to all of the baseline <br />of the permit, almost all of the <br />mountain shrub or big sagebrush. <br />area of meadow vegetation along <br />the subsequent disturbed area. <br />data for vegetation in Chapter K <br />pre-mining communities were <br />The Northern #1 site had a small <br />drainage channel that bisected <br />The mountain shrub community consists of predominately oak and <br />serviceberry with very little grass cover. Total graminoids <br />comprised less than 12% cover. Total vegetative cover is 65.1. <br />Most of the shrubs reach up to 0.5 meters high. Canopy cover for <br />this community is approximately 50~. From the enclosed table, a <br />"C" factor for this community at 60% cover is .075. At 80~ cover, <br />it is .039. Interpolating between these numbers, the "C" factor <br />at 65.1 cover is .066. <br />lJ <br />l~-~.E <br />?~/~ <br />
