• and Carex spp. were the major graminoids, while Mountain 5nowberry and puercus <br />sp. were the main shrubs. <br />Willow/Redtop (Table 2.4-21) <br />The Willow/Redtop vegetation Type hod the highest annual production with 284 <br />gm/0.5 m2. The grasses had a relative biomass of 83%, forbs, 17°,G, and shrubs about <br />I%. <br />Subirrigated Shrub (Tables 2.4-22 and 2.4-23) <br />The affected area in this vegetation Type hod an annual production of 180 gm/0.5 <br />m2, the second highest in productivity. The shrubs contributed a relative biomass of <br />60°,6. The major shrub species were Wood's Rose, Willows, and Mountain 5nowberry. <br />The grasses and forbs each hod a relative biomoss of about 20°~. The production rate <br />for the control area was considerably below That of the affected area. Total annual <br />production in The control area was only 80 gm/0.5 m2. Of This 80 grams, forbs had <br />• the largest relative production with 43 %. Grasses and shrubs each contributed obout <br />30°~. Willow (17°,6) and Wood's Rose (6%) were the dominant shrubs. <br />Sagebrush/5nowberry (Tables 2.4-24 and 2.4-25) <br />The Sagebrush/5nowberry unit had a total annual productivity of 71 gm/0.5 m2 <br />in the affected area and 66 gm/0.5 m2 in the control area. Of the 66 grams in the <br />affected area, shrubs were the major contributor with a relative biomass of 64;0. <br />The dominant shrubs were Big Sagebrush, 5nowberry, and Silver Sogebrush. Relative <br />biomass for the grasses was 21% and for the forbs 15%. In the control area, relative <br />biomass values for shrubs, grasses and forbs was 75%, 14%, and II%, respectively. <br />Big Sagebrush, 5nowberry, and Silver Sagebrush were The main shrub species. <br />Mountain Shrub (Tables 2.4-26 and 2.4-27) <br />The Mountain Shrub vegetation type had a production value of 69 gm/0.5 m 2 for <br />the affected area and 63 gm/0.5 m2 for the control area. In the affected area, <br />• shrubs and grasses contributed equally. Each life-form had a relative biomass of <br />46%. Gambel's Oak, 5nowberry, and Serviceberry were the dominant shrub species. <br />Revised 7-81 2.4-7 <br />
