Name: Artemisia tridentata ssp. spiciformis Shrubland Alliance Reference: Western Ecology Working Group of... Description: This is a poorly documented alliance known from the foothills and lower mountain slopes of the northern Rocky Mountains of east-central and southeastern Idaho and probably western Wyoming. This alliance is found at the upper elevation range of Artemisia tridentata ssp. vaseyana, from 2590 to 3205 m (8500-10,500 feet) on deep to very deep, well-drained soils of mountain slopes and bottoms in zones of higher snow accumulation. Annual precipitation often exceeds 18 inches and occurs primarily as snow. The shrub layer ranges from 0.5-1.5 m tall, and shrub canopy cover is 10-60%, of which Artemisia tridentata ssp. spiciformis contributes at least 40% relative cover. Other shrubs that may be present include Artemisia tridentata ssp. vaseyana, Symphoricarpos oreophilus, and Chrysothamnus viscidiflorus. Perennial graminoid cover is typically less than 20%. Common species include Bromus carinatus and Carex geyeri.  Accession Code: VB.CC.18647.ARTEMISIATRIDEN Plot-observations of this Community Concept: 0
