Woody Plant Density - - <br />• (Table 7) <br />Native shrubs averaged 1,862 individuals per acre. Together, chokecherry and Saskatoon <br />serviceberry composed nine-tenths of this total. The balance comprised Gambel's oak (Quercus <br />gambelii), prickly rose (Rosa says), mountain snowberry, and bitterbrush. There were an average <br />of 32 box elder individuals per acre in this area. Total woody plant density was 1,894 individuals <br />per acre. <br />PECOCO Pasture Reclaimed Area <br />(Photographs 13-16) <br />Cover <br />(Table 8) <br />The dominant Iifeform in this reclamation unit was introduced perennial cool season grasses; they <br />averaged over 51 percent of total vegetation cover. Intermediate wheatgrass composed almost <br />nine-tenths of this total. Russian wildrye, orchard grass, smooth brome, and crested wheatgrass <br />(Agropyron desertorum) composed the balance. Timothy was also present in this area. <br />Introduced perennial (orbs were the second most abundnat Iifeform, averaging 19% of total <br />vegetation cover, with cicer milkvetch contributing nearly three-fourths to the Iifeform total. The <br />remaining quarter was composed of alfalfa and Canada thistle. Curly dock (Rumex crispus) was <br />• also present in this area. Native perennial cool season grasses averaged 13% of total vegetation <br />cover. The largest contributor was western wheatgrass with slightly over one-third of the total. <br />Agassiz bluegrass added one-tenth to the total and basin wildrye added more than Iwo-tenths this <br />total. Mountain brome, Rocky Mountain fescue, and slender wheatgrass each averaged about <br />one-tenth of this lifeform's total. Introduced annual 8 biennial forbs contributed 6% to total <br />vegetation cover, comprising nine species, three of which were quantitatively encountered. <br />Yellow sweetclover was the most abundant with nearly half of the Iifeform total; hound's tongue <br />and twolobe speedwell composed the balance with six other species observed as present in this <br />area. Native shrubs accounted for 6% of total vegetation cover. Of this, big sagebrush made up <br />over half and mountain snowberry made up four-tenths. Most of the remainder was Woods' rose <br />and Saskatoon serviceberry was scattered in immeasurable amounts. Native annual and biennial <br />forbs, adding up to 3% of total vegetation cover, mostly comprised gumweed (90%) and bigfruit <br />willowherb (10%) (Epilobium brachycarpum). Native perennial forbs contributed just 1 % to total <br />vegetation cover. Thirteen species were present, four of which contributed quantitatively. Mule's <br />ear (Wyethia amplexicaulis), wild tarragon (Oligosporus dracunculus ssp. glaucus), blue Flax, and <br />western yarrow each accounted for one fourth of the Iifeform total. Introduced annual grasses <br />(entirely Japanese brome) added 0.6% to total vegetation cover. One native annual grass, six- <br />• weeks fescue (Vulpia octoflora) was also present. <br />10 <br />
