Name: Artemisia tridentata (ssp. tridentata, ssp. xericensis) / Pseudoroegneria spicata Shrub Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This is a tall-shrub type from deep soils in basins and foothills of the Idaho, Montana and Wyoming Rocky Mountains west to eastern Washington, eastern Oregon, and northeastern California. Stands of this type grow in deep, generally alluvial soils of fans, swales, and draws in intermountain basins and in the foothills of the surrounding mountains. <i>Artemisia tridentata ssp. tridentata</i> dominates the shrub layer, which may contain <i>Chrysothamnus</i> spp. and <i>Artemisia tridentata ssp. wyomingensis</i>. Shrub cover generally ranges from 10-25%, but may exceed 25% in some stands. <i>Pseudoroegneria spicata</i> dominates the understory in good condition stands, which may also contain a variety of other graminoids and forbs. <i>Bromus tectorum</i> is common in degraded stands. The species composition of this type is very similar to ~<i>Artemisia tridentata</i> ssp. <i>wyomingensis / Pseudoroegneria spicata</i> Shrubland (CEGL001009)$$ (which grows on shallower, drier soils), but <i>Artemisia tridentata ssp. tridentata</i> dominates the overstory in this association. Stands of this type occupy deeper soils than do stands of the shorter ~<i>Artemisia tridentata</i> ssp. <i>wyomingensis / Pseudoroegneria spicata</i> Shrubland (CEGL001009)$$, which may form the surrounding matrix vegetation.  Accession Code: VB.CC.34409.CEGL001018 Plot-observations of this Community Concept: 0
