Name: Sarcobatus vermiculatus / Sporobolus airoides Shrubland Reference: Western Ecology Working Group of... Description: This association occurs in the Columbia and Wyoming basins, Colorado Plateau and western Great Plains from eastern Oregon, central and northeastern Wyoming, northwestern and southeastern Colorado, western New Mexico and eastern Utah. Stands of this type usually occur as small, relict patches on level to gently sloping valley floors, on alluvial fans along intermittent washes and streams, and on abandoned stream terraces with fine-textured to sandy, alkaline soils derived from alluvium. The water table rarely reaches the surface, and these sites flood only occasionally. Elevations range from 1180 to 1960 m (3870-6420 feet) in Colorado, New Mexico and Utah. <i>Sarcobatus vermiculatus</i> typically dominates the open to moderately dense shrub layer with between 10 and 50% cover and includes sparse and open steppe stands with 5-10% shrub cover. Other shrubs present with low cover may include <i>Atriplex canescens, Ericameria nauseosa</i><i>, Artemisia tridentata ssp. wyomingensis</i>, and <i>Artemisia tridentata ssp. tridentata</i>. The herbaceous understory is typically dominated by <i>Sporobolus airoides</i>, usually with a number of other species present, including <i>Pascopyrum smithii, Hordeum jubatum, Hesperostipa comata, Bouteloua gracilis, Elymus elymoides, Elymus lanceolatus ssp. lanceolatus</i>, and <i>Distichlis spicata</i>. Forbs generally contribute little cover, although several weedy or exotic forbs may be abundant.  Accession Code: VB.CC.31898.CEGL001368 Plot-observations of this Community Concept: 0
