RESULTS AND DISCUSSION <br /> <br /> Vegetative Cover <br /> Total plant cover measured at the Meadows No. 1 Mine ranged from 44.0 percent to 67.0 percent. <br /> Mean total plant cover was 56.4 percent (n = 13). Soil accounted for approp mately 23.0 percent of total <br /> ground cover (range = 14 [0 34 percent) whereas litter comprised 18.4 percent (range = 17 to 25 percent) <br /> and rock accounted for an average of 2.2 percen[ (range = 0 to 7 percent) . No lichens or moss were <br /> observed along the cover transects. The contributions of individual plant species to total vegetative cover <br /> are shown on Table 1. Perennial grasses account for most of the total plant cover observed on the site. <br /> TABLE 1 <br /> Summary of Vegetation Cover At <br /> Sun Coal Company's Meadows No. 1 Mine <br /> Absolute Cover Relative Cover <br /> Species (Percent) (Percent) <br /> Asrragalas titer 10.6 18.8 <br /> Phleum pratense 9.4 16.7 <br /> Bromus biebersteinii 8.8 15.6 <br /> Festuca ovina 6.1 10.8 <br /> Bromus ntarginatus 4.5 8.0 <br /> Agropyron sntithii 4.4 7.8 <br /> Stipa viridula 3.9 6.9 <br /> Agropvron riparium 2.7 3.7 <br /> Festuca arizonica 1.3 2.3 <br /> Lactuca serriola 1.2 2.1 <br /> Uniden[ifiable fortis 0.9 1.6 <br /> Cirsium arvense 0.8 ].4 <br /> Grtndelia squarrosa 0.5 0.9 <br /> Elvmus cinereus 0.3 0.5 <br /> Agropyron dasystach}vm 0.3 0.5 <br /> Agropyron cristarum 0.3 0.5 <br /> Unidentifiable grasses 0.3 0.5 <br /> Agropvron trichopharunt 0.2 0.4 <br /> Trijolium incarnatum 0.2 0.4 <br /> Agropvron trachvcaulunt 0.2 0.4 <br /> Koeleria pyrantidata 0.1 0.2 <br /> Total 56.4 100.0 <br /> <br /> <br />4 <br /> <br />
