Name: Larrea tridentata / Pleuraphis rigida Desert Shrubland Reference: NatureServe Biotics 2019 Description: This scrub association is found at low to upper elevations in the Colorado and Mojave deserts in California. Vegetation is characterized by an open to patchy shrub canopy (4-15% cover) dominated by <i>Larrea tridentata</i> with an herbaceous layer dominated by perennial native grass <i>Pleuraphis rigida</i>. Many other shrubs are often present, including <i>Ambrosia dumosa, Cylindropuntia</i> spp., <i>Krameria</i> spp., <i>Lycium</i> spp., and <i>Senna armata</i>. Occasional emergent <i>Olneya tesota</i> or <i>Yucca brevifolia</i> trees are sometimes present. The herbaceous layer is typically sparse to open and is characterized by <i>Pleuraphis rigida</i> with associated grasses and forbs such as <i>Dasyochloa pulchella</i> and <i>Lupinus</i> spp., and exotic annuals <i>Bromus madritensis</i> and <i>Erodium cicutarium</i>. A biological soil crust is often present. Stands occur in valleys, floodplains, alluvial fans/bajadas, mid and lower slopes of hills, ranging from 133-1350 m elevation. Sites occur on gentle to moderately steep slopes, frequently with easterly aspects. Soils are variable, ranging from loamy sand and sandy loam to finer-textured silty loams and clay loams that tend to be noncalcareous and derived from alluvium, metamorphic rocks, basalt, and granitic parent materials.  Accession Code: urn:lsid:vegbank.org:commConcept:34441-{B59039F1-C979-47B3-915A-444045BC13F3} Plot-observations of this Community Concept: 0
