MIXED MOUNTAIN SHRUBLAND <br />• The Mixed Mountain Shrubland type is widely distributed on mid- <br />slopes, with Big Sagebrush Shrublands occurring both above and <br />below. The best development of the Mixed Mountain Shrubland is <br />on east-facing slopes. <br />The vegetation cover is closed, with relatively little bare ground. <br />Evidence of soil slumping exists in varying degrees, but little <br />surface erosion occurs. The soil surface has a slight to extensive <br />organic matter cover. Few rocks are visible. The Mixed Mountain <br />Shrubland type is dominated by Snowberry, which often forms a <br />dense cover about 0.5 m in height, along with Utah Serviceberry, <br />Big Sagebrush, and Gambel's Oak. Elk Sedge and White-flowered <br />Peavine (Lathyrus leucanthus) are the .herbaceous dominants. An <br />additional 39 herbaceous species also occur. Percent frequency, <br />percent cover, density and height are listed in Table J13 for <br />species of the Mixed Mountain Shrubland type. <br />• The Mixed Mountain Shrubland type is used primarily as wildlife <br />cover and secondarily by domestic grazing animals. Deer use <br />the vegetation for both browse and cover. Blue Grouse also use <br />it for cover. No evidence of overgrazing or overbrowsing was <br />found. <br />HIGH ELEVATION BIG SAGEBRUSH SHRUBLAND <br />High Elevation Big Sagebrush Shrubland is widely distributed <br />on plateau gully bottoms, on the lower portions of the slopes, <br />and on ridgetops and flattened areas of the plateau. <br />Vegetation is open, with considerable bare ground and evidence <br />of erosion. The soil surface does not have extensive organic <br />matter. <br /> <br />J-7 <br />
