Name: Artemisia tridentata ssp. wyomingensis / Elymus elymoides Shrubland
Reference: Western Ecology Working Group of...
Description: Little environmental information is available for this association. Some authorities believe that this association is either ecotonal or the result of grazing or burning other types of sagebrush shrublands. Documented sites occur between 1689 and 2134 m (5540-7000 feet) elevation on gentle to moderate slopes in northwestern Colorado, northeastern Nevada, southern Idaho and possibly in eastern Idaho and southeastern Oregon. Aspect is not important in determining the distribution of this association. Soils are deep and well-developed and may have a loam or clay loam texture. The unvegetated surface is dominated by bare soil, with little litter present in grazed stands. The vegetation of this sagebrush shrubland is characterized by an open layer of <i>Artemisia tridentata ssp. wyomingensis</i> with between 20 and 35% cover, and a mixed grass understory dominated or codominated by <i>Elymus elymoides</i> with between 5 and 15% cover. <i>Chrysothamnus viscidiflorus, Purshia tridentata, Sarcobatus vermiculatus, Symphoricarpos oreophilus, Atriplex confertifolia</i>, and <i>Krascheninnikovia lanata</i> may also be present in the shrub layer, although cover of these species is generally very low. Other important graminoids include <i>Pascopyrum smithii, Festuca idahoensis, Poa secunda, Achnatherum hymenoides, Hesperostipa comata, Leymus cinereus</i>, and <i>Poa fendleriana</i>. <i>Bromus tectorum</i> may be important in disturbed stands. Forbs are generally sparse and vary greatly from site to site. Some common species include <i>Achillea millefolium, Eriogonum ovalifolium, Lupinus argenteus, Packera multilobata (= Senecio multilobatus), Cryptantha</i> spp., <i>Sphaeralcea coccinea</i>, and <i>Phlox hoodii</i>.
