The only recorded grass-like species present is Carex geyeri. According to 1980 <br />data this species provided 48.9% of the herbaceous cover as indicated in Table <br />2.3-5. This value is a much more accurate measure of the actual importance of <br />Carex geyeri in this range site. <br />The final range site (C) is a big sagebrush-grass type used for domestic grazing <br />and wildlife habitat. In this range site, the shrubs provide 61.7% of the rela- <br />tive aerial cover. Grass are next in importance and provide 29.2% (Table 2.3-6). <br />Forbs and grass-like plants are of minor importance based on 1979 cover data. <br />The dominant shrubs are Artemisia tridentata and Symphoricarpos oreophilus (Table <br />2.3-6). The 1979 cover data agree closely with 1980 stem density data (Table <br />2.3-15) which shows the same relationship. <br />The 1979 and 1980 data indicate that Heterotheca villosa, Salsola kali, and <br />Copious spp., are the dominant forbs (Table 2.3-6, 2.3-7). <br />The dominant grass species are Poa pratensis, Agropyron smithii, and Bromus <br />• inermis. This order was exactly the same in both [he 1979 and 1980 vegetation <br />inventories after analysis. <br />2.3.1.3 Habitat Descriptions <br />Following are descriptions of dominant plant species present in the two major <br />vegetation types within the proposed mine plan area. Descriptions are arranged <br />by lifeform and are taken from "The Range Plant Hand Book" (U.S.F.S., U.S. Dept. <br />of Agri., 1937). Table 2.3-8 is a summarization of habitat descriptions as pre- <br />sented in PIN. <br />• <br />2-71 <br />REVISED FEB 13 '$ ~ <br />
