Name: Artemisia tridentata - Atriplex canescens - Sarcobatus vermiculatus / (Achnatherum hymenoides) Shrubland Reference: Western Ecology Working Group of... Description: This desert community is associated with sand dunes, which are found along the windward (eastern in the northern Great Basin) edge of large playa basins. Aspects and slopes of the dunes vary, but most are north-south, along the eastern playa edges of a completely flat landscape. In addition to the shrubs Artemisia tridentata, Atriplex canescens, and Sarcobatus vermiculatus, other occasional codominants include Chrysothamnus viscidiflorus, Ericameria nauseosa (= Chrysothamnus nauseosus), and Grayia spinosa (= Atriplex spinosa). The most abundant but sparse grass is Achnatherum hymenoides (= Oryzopsis hymenoides) although Hesperostipa comata (= Stipa comata), Elymus lanceolatus, and Leymus cinereus are occasionally found. Bare, alkaline sand provides significant cover. This community rapidly vanishes on the adjacent Artemisia tridentata ssp. wyomingensis-dominated slopes. This dune association represents a rich floral assemblage as compared to surrounding salt desert scrub and playa communities. This is attributable to higher soil temperatures in spring promoting early growth, lower salt concentrations, and greater accumulation of wind-blown seeds.  Accession Code: VB.CC.25660.ARTEMISIATRIDEN Plot-observations of this Community Concept: 0
