Name: Allenrolfea occidentalis Wet Shrubland Reference: NatureServe Biotics 2019 Description: This is a sparsely vegetated shrubland found on seasonally wet, alkaline playas, intermittent floodplains or along washes in saline overflow areas below 1680 m (5500 feet) elevation. The dominant species, and playa communities in general, are widely distributed throughout the Intermountain West, ranging from southeastern Oregon south to Texas. These shrublands or barrens are flat to extremely low-gradient, almost always in desert ecosystems with less than 18 cm (7 inches) of rain per year, and usually in areas with very poor drainage that flood during rare rainstorms. Playas and washes dominated by <i>Allenrolfea occidentalis</i> generally appear to be small, rare, and poorly understood throughout their range. <i>Allenrolfea occidentalis</i> dominates the shrub layer, but cover is often quite low, ranging from 20% to less than 1%. Most stands have barren playa forb understories, but grasses, including <i>Leymus cinereus, Distichlis spicata, Sporobolus airoides</i>, and <i>Sporobolus wrightii</i>, and succulent forbs, such as <i>Suaeda suffrutescens var. detonsa, Salicornia</i> spp., and <i>Nitrophila</i> spp., are occasionally found. Most stands occur in a matrix of <i>Sarcobatus vermiculatus</i>- or <i>Atriplex canescens</i>-dominated shrublands, and in small stands, either <i>Sarcobatus vermiculatus</i> or <i>Atriplex canescens</i> can occur throughout the community.  Accession Code: urn:lsid:vegbank.org:commConcept:29897-{64D5D6D7-319A-4E1C-8684-D5C0B6AA29F2} Plot-observations of this Community Concept: 18
