e <br />ESPEY, HUSTON &ASSOCIATES, INC. <br />L_J <br />3.2.1 Meadow Community <br />A meadow community dominated by perennial graminoids occurs on the <br />valleys between mountainous slopes. Relief is relatively level. The major soil type <br />is the Straw silty clay loam which is deep and somewhat poorly drained. This climax <br />community grades into the big sagebrush community rather abruptly as slope <br />increases and the available moisture gradient decreases. Areas of standing water <br />2-10 centimeters deep ezist in topographic depressions of this community through- <br />out the growing season. <br />Cover <br />The vegetation of the meadow community is represented by 42 species of <br />plants, 22 graminoids, 19 forbs and 1 shrub. Graminoids are the dominant life form <br />contributing 75 percent of the total estimated vegetation cover. Forbs constitute <br />• 25 percent of the estimated cover while shrubs aze extremely raze representing 0 1 <br />percent of the estimated vegetation cover. Total estimated vegetation cover i 97.8 <br />percent. Litter cover is high (57.8 percent), rocks were neazly non-existent, soil <br />cover was low (8.5 percent), and mosses were present in low cover (0.4 percent) (see <br />Table K-2). Rubber rabbitbrush (Chrysothamnus nauseosus) is the only shrub in the <br />community. Total cover for this shrub was 0.1 percent. <br />A mixture of cool season mid to tall graminoids chazacterizes the <br />vegetation cover. The dominant graminoids aze bluegrass (Pon agassizensis) (10.5 <br />percent), fieldclustered sedge (Cazex praegracilis) (10.4 percent), baltic rush (Juncos <br />azcticus) (10.3 percent), Nebraska sedge (Cazex nebraskensis) (10.1 percent) and <br />Canada bluegrass (Pon compressa) (9.5 percent). Other common grasses are: <br />western wheatgrass (7.9 percent) in more xeric states, smooth brome (Bromopsis <br />inermus) (5.4 percent) an introduced species in more disturbed azeas, quackgrass (4.3 <br />percent), redtop (Agrostis giQantea) (2.2 percent) and little bazley (FIordeum <br />pusillum) (1.1 percent). Other grasses occurring less frequently aze: tufted <br /> <br />K-14 <br />
