r <br />(Melilotus officinalis) and salsify (Tragopogon dubius ssp. major) were' also important. • <br />Native shrubs (entirely big sagebrush) accounted for 0.2 percent of tonal vegetation cover. <br />Total vegetation cover avers~ged 55.5 percent. Standing dead, litter, bare soil, and rock <br />cover averaged 0.9, 31.9, 10.9, and 0.8 percent, respectively. Species density averaged <br />27.5 species per 100 sq. m. <br />Herbaceous Production (Table 2) <br />Total herbaceous production for alfalfa averaged 528.2 pounds per acre. Total herbaceous <br />production for all other species averaged 2,157.3 pounds per acre. Tonal herbaceous <br />production averaged 2,685.5 pounds per acre. <br />Shrub Density (Table 3) <br />Native shrub, the only woody life form observed in this unit, averaged 125.5 individuals <br />per acre.j Mountain snowberry (Svmohoricarpos rotundifolius) accounted for more than <br />half of this but big sagebrush (Seriphidium tridentatum) was also important. <br />1892 Reclaimed Areas (Photographs 5 through 8) • <br />Cover (Table 4) <br />Introduced perennial forb was the dominant life form in this unit with 27.0 percent of total <br />vegetation cover. Cicer milkvetch and alfalfa accounted for most of this but Canada thistle <br />(Breea arvensis) also contributed. Native perennial forbs averaged 7.:i percent of total <br />vegetation cover. Western yarrow (Achilles lanulosa), groundsmoke (C3ayophytum <br />i fusum ssp. parviflorum), showy goldeneye (Heliomeris multiflora), and American vetch <br />(Vicia americans) all contributed to this cover percentage. Introduced annual and biennial <br />forbs averaged 12.5 percent of total vegetation cover. Twolobe speedweall accounted for <br />more than half of this average. Yellow sweetclover was also important. Native annual and <br />biennial forbs averaged 2.3 percent of total vegetation cover. Native perennial cool season <br />grasses averaged 21.3 percent of total vegetation cover. Agassiz bluegrass and mountain <br />brome (Ceratochloa carinata) accounted for most of this. Slender wheeitgrass (F,Ivmus <br />trachycaulus), giant wildrye (Levmus cinereus) and Sandberg bluegrass (Poa secunda) <br />were also important.
