Reference: EcoArt 2002
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$.
