Name: Peucephyllum schottii - Eucnide urens - Pleurocoronis pluriseta Shrubland Reference: NatureServe Biotics 2019 Description: This sparse to open shrubland association occurs at low to upper elevations in the Mojave Desert and southern Great Basin in Arizona, southern Nevada, and California. Stands are characterized by the presence of shrubs/subshrubs <i>Eucnide urens</i> and/or <i>Peucephyllum schottii</i> with up to 12% cover. Other shrubs that are often present include <i>Encelia farinosa, Eriogonum fasciculatum</i>, and <i>Pleurocoronis pluriseta</i>. Sometimes <i>Pleurocoronis pluriseta</i> is dominant with or without the other two indicator shrub species of this association; other instances <i>Peucephyllum</i> may be dominant or codominant. If present, the sparse herbaceous layer has up to 10% cover and is composed of <i>Nicotiana obtusifolia, Pterostegia drymarioides, Sphaeralcea ambigua</i>, and exotic annual grass <i>Bromus rubens</i>. Nonvascular species may be present and sometimes form a biological soil crust. Stands occur where bedrock and/or boulders dominate the surface cover at 150-1300 m elevation. Slopes are gentle to abrupt as it is found primarily on channel walls or on steep and bouldery, high to midslope positions. Soils are typically clay loam, and are derived from a variety of substrates.  Accession Code: urn:lsid:vegbank.org:commConcept:34443-{3CCB14D9-B423-42CF-B9AD-5EECB7AB671C} Plot-observations of this Community Concept: 0
