Name: A.818
Reference: EcoArt 2002
Description: This alliance occurs in the Great Basin and Colorado Plateau on bajadas, pediments and valleys, including pumice flats. Substrates and parent materials are variable. Soils are shallow, well-drained, calcareous, alkaline and often gravelly. Vegetation included in this shrubland alliance is characterized by having a sparse to dense shrub layer dominated by ~Ericameria parryi (= Chrysothamnus parryi)$. Shrub associates include ~Artemisia tridentata, Krascheninnikovia lanata, Ephedra$ spp., and ~Purshia tridentata$. The sparse to moderate herbaceous layer is dominated by graminoids such as ~Bouteloua gracilis, Pleuraphis jamesii (= Hilaria jamesii), Sporobolus airoides, Achnatherum occidentale ssp. pubescens (= Stipa occidentalis var. pubescens)$, and ~Elymus elymoides$. Perennial forbs are generally sparse. Some stands may have scattered ~Juniperus$ spp. and ~Pinus$ spp trees. Diagnostic of this shrubland alliance is the dominance of ~Ericameria parryi$ in the shrub layer.
