grasses. Observed but not quantitatively were native annual and biennial forbs, moss, and a <br />• parasite. <br />PRODUCTION <br />(Table 14) <br />Total production for the Wadge Pasture in 2003 was 3,422.4 Ibslacre. Alfalfa averaged 1,084.5 <br />Ibs/acre while all other herbaceous species accounted for 2,337.2 Ibs/acre. <br />WOODY PLANT DENSITY <br />(Table 15) <br />There were 590.9 native shrub stems/acre in 2003 in Wadge Pasture. On the average, 437.1 of <br />these were big sagebrush, while an average of 0.8 dead big sagebrush were counted as well. <br />Mountain snowberry averaged approximately 140.8 stems/acre. Also contributing were saltbush <br />(Atriplex canescens), Douglas rabbitbrush, bitterbrush, Saskatoon serviceberry, and Arkansas <br />rose. <br />Alkali Sagebrush Reference Area <br />(Photographs 21-24) <br />• COVER <br />(Table 16) <br />Native shrubs dominated the vegetation in this reference area in 2003. Of the 58.3 percent total <br />vegetation cover contributed by the lifeform, 7/10fhSwas composed of alkali sagebrush. Mountain <br />snowberry, big sagebrush, Saskatoon serviceberry, and Douglas rabbitbrush were all <br />quantitatively observed. With 19.5 percent total vegetation cover, native perennial forbs were <br />also common. Arrowleaf balsamroot (Balsamorhiza sagittata) accounted for 6.91 percent total <br />vegetation cover; big-flowered onion (Allium macropetalum) comprised 4.2 percent; mule's ear <br />(Wyethia amplexicaulis) measured 2.4 percent of the total. Several other species accounted for <br />less than 2% total vegetation cover. Native perennial grasses contributed significantly to total <br />vegetation cover with 16.8 percent. Western wheatgrass dominated this lifeform with over 3/5`"s <br />of the total. Lifeforms measuring less than five percent total vegetation cover included introduced <br />perennial cool season grasses, native annual and biennial forbs, introduced annual and biennial <br />forbs. Introduced perennial forbs were also present. <br />Total vegetation cover was 32.9 percent in 2003. The remainder was composed of 52.1% bare <br />soil, 10.8% litter, 3.8% standing dead, and 0.3% rock. Species density averaged 18.7 species <br />per 100 sq.m. <br />11 <br />
