Name: Artemisia tridentata ssp. tridentata / Pleuraphis jamesii Shrubland Reference: Western Ecology Working Group of... Description: This association has been described from the Colorado Plateau in southeastern Utah and may occur in parts of Colorado, New Mexico and Arizona. Most stands occur on valley floors, alluvial flats and on the terraces of intermittent drainages. A few stands have been reported from mesas. Sites are located between 1866 and 2200 m (6122-7220 feet) elevation on level to gentle slopes (&lt;5%). Up to 80% of the unvegetated surface is covered by bare ground. Soils are generally deep, calcareous and alkaline sandy loams or clay loams derived from alluvium. This association occupies dry sites on valley floors in the Colorado Plateau. Total vegetation cover is variable; some disturbed stands may appear to be sparsely vegetated with total vegetation cover less than 10%. Stands are characterized by an open shrub canopy (5-35% cover) dominated by <i>Artemisia tridentata ssp. tridentata</i>. Associated shrubs may include <i>Chrysothamnus viscidiflorus, Ephedra viridis, Ericameria nauseosa, Gutierrezia sarothrae, Opuntia polyacantha, Atriplex</i> spp., and <i>Krascheninnikovia lanata</i>. Total woody canopy ranges from 5-35% cover. The sparse herbaceous layer (5-15% cover) is dominated by graminoids such as <i>Pleuraphis jamesii (= Hilaria jamesii), Achnatherum hymenoides, Aristida purpurea, Bouteloua gracilis, Elymus elymoides</i>, and <i>Sporobolus cryptandrus</i>. Forbs are sparse and variable; species recorded from plots include <i>Castilleja linariifolia</i> and <i>Psoralidium lanceolatum</i>.  Accession Code: VB.CC.34222.CEGL001015 Plot-observations of this Community Concept: 0
