speedwell and hound's tongue (Gvnoglossum officinale) were also important. Native annual • and biennial (orbs averaged 1.4 percent of total vegetation cover. Native perennial forbs ~ averaged 4.2 percent of total vegetation cover. Groundsmoke was this life form's major cover contributor. Native shrubs (mostly big sagebrush and rubber rabbitbrush, i C~sothamnus nauseousus) accounted for 0.8 percent of total vegetation cover. I Total vegetation cover averaged 50.5 percent. Standing dead, litter, bare soil, and rock i cover averaged 2.1, 27.2, 19.3, and 0.9 percent, respectively. Species density averaged 26.9 individuals 100 sq. m. I i Herbaceous Production (Table 8) Alfalfa averaged 217.7 pounds of herbaceous production per acre. All other species averaged 1,548.8 pounds per acre. Total herbaceous production averaged 1,764.8 pounds per acre. Shrub Density (Table 9) Native shrubs, the only woody life form observed in this unit, averaged 376.4 individuals per acre. 'Rubber rabbitbrush (Chrysothamnus nauseosus) and big sagebrush accounted for most of these. Mountain snowberry was also important. Saskatoon serviceberry, Douglas rabbitbrush (Chrysothamnus viscidiflorus), and silver sagebrush (Seriohidium canum) were minor contributors. Wadge Pasture (Photographs 13 through 15) Cover (Table 10) Introduced perennial forb was the dominant life form in this unit with !i2.7 percent of total i vegetation cover. Atfalia accounted for most of this average but titer milkvetch was also important. Native perennial forbs averaged 1.6 percent of total vegetation cover. ~ Introduced annual and biennial forbs averaged 3.7 percent of total vegetation cover. Twolobe speedwell and salsify accounted (or most of this average. Big sagebrush, a native I shrub, averaged 1.6 percent of total vegetation cover and was the only shrub contributing measurably to cover. • r1 LJ 12
