<br />alnifolia dominate the overstory while S. Oreophilus dominates [he unders[ory. <br />Based on 1979 and 1980 vegetative aerial cover, [he dominant forbs in range site <br />(A) are Lathyrus leucanthus, Achilles lanulosa, and S[ellari jamesiana. (Tables <br />2.3-2 and 2.3-3) <br />The 1979 cover data indicates that [he dominant grass species are Poa fendleriana <br />and Poa pratensis. However, the 1980 vegetation data shows that Poa pratensis <br />and Agropyron smi[hii are the dominant grass species. In 1980, no Poa fendler- <br />iana was identified but 19 unidentified Poas were recorded which probably <br />included some Poa fendleriana. <br />In both years, 1979 and 1980, Carex grayeri has shown to be a major herbaceous <br />plan[ species. I[ is the only grass-like species to date sampled in the mountain <br />shrub range sites. <br />The other mountain shrub range site (B), is also dominated by shrubs (67.1% of <br />_ the total relative cover based on 1979 data). The remaining cover is evenly <br />divided between forbs and grasses with 1.5% relative cover by life form taken up <br />by grass like plants (Table 2.3-4). <br />The dominant shrub in this range site by cover is Symphoricarpos oreophilus based <br />on 1979 cover data. In terms of stem density the dominant shrubby species are <br />Quercus gambellii and Symphoricarpos oreophilus (Table 2.3-15). However, range <br />site (B) was no[ sampled adequately statistically for cover by species in 1979 <br />with the five cover tcansects used. It was sampled at [he proper statistical <br />intensity for total cover [hough as required by OSM regulations. Therefore, [he <br />dominant shrubs in range site (B) are based on 1980 shrub stem density data. <br />Based on 1979 and 1980 cover data, [he dominant forb in range site (B) is Lath- <br />yrus leucanthus. In 1979, [his species comprised 4.5% of the relative cover and <br />6.9% in 1980 (Tables 2.3-4, 2.3-5). <br /> The major grass species is Poa pratensis based on the 1980 data. Again, the 1979 <br /> data is probably less accurate than [he 1980 data when attempting to define spe- <br /> cies dominance by cover due to the lower sampling intensity in 1979. <br />2-67 <br />
