Reference: EcoArt 2002
Description: This xeromorphic shrubland alliance occurs locally in washes in southwestern deserts from southern California to the Sonoran Desert, north into the southeastern Great Basin. Stands are restricted to growing in intermittently flooded channels and terraces on bajadas and alluvial fans. Substrates are coarse-textured soils derived from alluvium. Disturbance from flooding scours out existing vegetation and creates habitat for the seedlings of the dominant/diagnostic species, ~Ericameria paniculata$. The vegetation is characterized by a moderately dense, xeromorphic, typically short-shrub layer (2 m tall) that is dominated by ~Ericameria paniculata$. Individuals may reach 4 m. Other shrubs and dwarf-shrubs present may include ~Ambrosia eriocentra, Brickellia incana, Ephedra californica, Ephedra nevadensis, Encelia farinosa, Encelia virginensis, Eriogonum fasciculatum, Gutierrezia sarothrae, Hymenoclea salsola, Opuntia chlorotica, Salvia dorrii$, or ~Stephanomeria pauciflora$. Occasional emergent tall shrubs or small trees may be present such as ~Acacia greggii$ or ~Chilopsis linearis$. The herbaceous layer is generally sparse or absent.
