1 <br />' Yegembon Sampling Jor /996 <br />' A total of nine grasses were surveyed on the disturbed area. Of those grasses, seven were cool- <br />season and two were warm-season. A total of six out of the nine grasses surveyed comprised a <br />relative cover of 3.0 percent or greater. Blue grama and side-oats grama comprised 8.4 and <br />' 3.8 percent of the relative vegetative cover, thus meeting the perennial warm-season diversity <br />requirement. Crested wheatgrass, western wheatgrass, thickspike wheatgrass, and smooth brome <br />fall within the cool-season perennial grass diversity requirement. <br />' Of the four perennial forb species sampled on the disturbed azea, only one exhibits a relative cover <br />of greater than 3.0 percent. The other three species each a had relative cover equal to 0.8 percent. <br />However, not one of the three perennial forbs sampled in the reference area was present in an <br />abundance greater than 3.0 percent. <br />' Only one shrub species was sampled in the disturbed area, representing a very minor portion of <br />relative cover (0.8 percent). Two shrub species were sampled in the reference area, resulting in <br />' one species with a relative cover greater than 3.0 percent. <br />Vegetative cover on the reference area was higher than the disturbance area at 14.6 percent <br />' (Table 3). Bare ground and litter comprised 38.4 and 45.3 percent of the area, respectively. <br />Rock accounted for 2.1 percent of the cover. Like the disturbed area, perennial grasses made up <br />most of the vegetative relative cover, 88.2 percent on the reference area. A wider variety of <br />' shrubs and a higher percentage of shrubs (6.8) and annual forbs (4.3) were also found (Table 3). <br />Annual forbs accounted for a minor percentage of vegetative cover (0.6 percent ). <br />' Tables 4 and 5 present the study and reference area comprehensive plant species lists for the CCM <br />No. l Mine. Grasses, forbs, shrubs, and weedy species are listed in the tables by scientific and <br />common names. <br />1 <br />1 <br /> <br /> <br /> <br />1 <br />1 <br />' bm1.OSJ`DSJ.1996~Srpiaober IJ. 1996 A-6 <br />
