Name: Larrea tridentata - Encelia farinosa - Pleurocoronis pluriseta Desert Shrubland Reference: NatureServe Biotics 2019 Description: This association is found at low to mid elevations in the Mojave Desert in Arizona, California and southern Nevada. Vegetation is characterized by a sparse to open shrub canopy (7-16% cover) codominated by <i>Encelia farinosa</i> with <i>Larrea tridentata</i> and <i>Pleurocoronis pluriseta</i> characteristically present to codominant. Other shrubs frequently present include <i>Ambrosia dumosa, Bebbia juncea, Eriogonum fasciculatum, Trixis californica</i>, and <i>Viguiera parishii</i>. If present, the herbaceous layer is sparse and composed of a mixture of grasses and forbs such as <i>Achnatherum speciosum, Adenophyllum porophylloides, Amsinckia</i> spp., <i>Eriogonum inflatum, Cryptantha</i> spp., <i>Stephanomeria pauciflora</i>, various native annuals, and exotic annual grasses <i>Schismus</i> spp. Nonvascular plants include cryptogamic crust and lichens. Stands are found in rocky upland on mid to high slopes ranging from 250-1050 m elevation. Sites occur on gentle to steep slopes on primarily southerly aspects. Soils are rocky and shallow with variable textures ranging from loamy sand to clay and are derived from a variety of substrates such as alluvium, dacite, dune sand, gneiss, granodiorite, rhyolite, sandstone, and schist. Disturbance from exotic species is typically low in this association.  Accession Code: urn:lsid:vegbank.org:commConcept:34440-{22901B92-7FCD-48B2-9332-8BAD76A05D76} Plot-observations of this Community Concept: 0
