Interim Monitoring <br />1999 RECLAIMED AREA <br />(Photographs 13-16) <br />Cover <br />(Table 3) <br />Native perennial cool season grasses and introduced perennial cool season grasses had the <br />greatest average cover values: 11.1 % and 6.1%, respectively, out of 32.0% total vegetation cover <br />(all hits). Common orchardgrass (Dactylic glomerata), an introduced perennial cool season <br />grass, and alfalfa (Medicago sativa), an introduced perennial forb, were the most abundant <br />species within their lifeforms (5.8% and 5.1%, respectively). Western wheatgrass (Pascopyrum <br />smithii), a native perennial cool season grass, was relatively common, with 2.9% cover. <br />Total average vegetation cover, for first hits, was 31.7%. Total average vegetation cover, for all <br />hits, was 32.0%. Standing dead, litter, bare soil, and rock each had 3.8%, 34.3%, 28.4%, and <br />1.9% cover, respectively (first hits). Average species density was 34.6 species/100 sq. m. <br />Production <br /> <br />I <br />(Table 4) <br />Total average production was 943.9 Ibs/acre. Introduced perennial fortis contributed the most <br />with an average of 339.0 Ibs/acre (approximately 36%). <br />Woody Plant Density <br />(Table 5) <br />Total average density of woody plants was 222.6 individuals/acre, composed entirely of native <br />shrubs. Mountain snowberry (Symphoricarpos rofundifolius) was the most abundant, with 115.3 <br />individualslacre, and big sagebrush (Seriphidium tridentatum) was second most abundant, with <br />34.4 individuals/acre. Antelope bitterbrush (Purshia tridentata) chokecherry (Padus virginiana <br />ssp. melanocarpa), Saskatoon serviceberry (Amelanchier alnifolia), Gambel oak (Quercus <br />gambelii), Woods' rose (Rosa woodsi~), and rubber rabbitbrush (Chrysothamnus nauseosus) had <br />moderate to low densities. <br />9 <br />
