Name: Hymenoclea salsola Shrubland Alliance Reference: Western Ecology Working Group of... Description: This alliance occurs in a variety of disturbed habitats in the southwestern deserts from southern California to the Sonoran Desert, north into the southeastern Great Basin. Stands may occur as either wetland/riparian or upland vegetation. Sites include washes and palustrine environments, valley bottoms, and alluvial flats. Wetland substrates are well-drained, coarse-textured soils that are moderately acidic to slightly saline. Upland substrates are shallow, coarse-textured soils often with a desert pavement. Disturbance from flooding, burning, and grazing animals creates habitat for this type. The vegetation is characterized by an open, xeromorphic shrub layer dominated by Hymenoclea salsola. Other shrubs and dwarf-shrubs present may include Atriplex confertifolia, Bebbia juncea, Brickellia incana, Senna armata (= Cassia armata), Ephedra californica, Encelia farinosa, Ericameria paniculata, Eriogonum fasciculatum, Larrea tridentata, Opuntia echinocarpa, Opuntia basilaris, Psorothamnus schottii, or Salazaria mexicana. Occasional emergent tall shrubs or small trees may be present such as Acacia greggii, Chilopsis linearis, Olneya tesota, Parkinsonia florida, or Psorothamnus spinosus. The herbaceous layer is generally sparse and often dominated by annual species, especially the introduced annual Bromus spp. such as Bromus madritensis and Bromus rubens.  Accession Code: VB.CC.22287.HYMENOCLEASALSO Plot-observations of this Community Concept: 0
