Name: Artemisia tridentata ssp. tridentata / Pleuraphis jamesii Shrubland
Reference: NatureServe Biotics 2019
Description: This association occurs from the Colorado Plateau to the Great Basin, south into the northern Mojave Desert. 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 with low cover may include <i>Atriplex</i> spp., <i>Chrysothamnus viscidiflorus, Ephedra viridis, Ericameria nauseosa, Gutierrezia sarothrae, Krascheninnikovia lanata, Lycium andersonii, Menodora spinescens, Opuntia polyacantha</i>, and <i>Picrothamnus desertorum</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, 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>.
