Name: Psorothamnus polydenius Shrubland Alliance
Reference: Western Ecology Working Group of...
Description: This shrubland alliance is found in drainage bottoms in the Great Basin. Elevation ranges from 670-2250 m. Sites include sandy alluvial flats, plains and washes, typically are flat to undulating, and occur on all aspects. The soils are well-drained, moderately deep and coarse-textured with a sandy surface over sandy loams. Soils are derived from sandy/gravelly alluvium. Stands have a sparse woody layer dominated by the xeromorphic, deciduous, subdesert shrub Psorothamnus polydenius. Other common shrubs and dwarf-shrubs present may include Atriplex canescens, Krascheninnikovia lanata, Tetradymia glabrata, and occasional Artemisia tridentata. The herbaceous layer ranges from sparse to possibly moderately dense, but no cover values are available. Frequent graminoids are Achnatherum hymenoides (= Oryzopsis hymenoides), Elymus elymoides, and the exotic annual Bromus tectorum. Common forbs consist of Phacelia spp., Abronia fragrans, Gayophytum ramosissimum, Mentzelia multiflora, Cleome lutea, Navarretia sp., and Sphaeralcea coccinea.
