Name: Yucca brevifolia / (Yucca baccata) / Pleuraphis jamesii - Bouteloua eriopoda Wooded Shrubland Reference: NatureServe Biotics 2019 Description: This association is commonly found at mid to upper elevations in the eastern and northern Mojave Desert in California and Nevada. It forms an open small-tree/tall-shrub canopy (1-6% cover) that is characterized by <i>Yucca brevifolia</i>, sometimes with <i>Juniperus osteosperma</i> present with an open short-shrub layer (&lt;3% cover) and a grassy understory dominated or codominated by diagnostic grasses <i>Pleuraphis jamesii</i> and/or <i>Bouteloua eriopoda</i>. <i>Yucca baccata</i> is often present in the short-shrub layer along with low cover of <i>Ephedra nevadensis</i> and <i>Cylindropuntia acanthocarpa</i>. This layer may be diverse in composition and include other associated shrubs such as <i>Eriogonum fasciculatum, Echinocereus engelmannii, Gutierrezia sarothrae, Krameria erecta, Psilostrophe cooperi</i>, and <i>Salazaria mexicana</i>. The open to moderately dense herbaceous layer (7-36% cover) is typically diverse though <i>Pleuraphis jamesii</i> and/or <i>Bouteloua eriopoda</i> are often dominant or codominant; other associated species include <i>Achnatherum speciosum, Eriogonum inflatum, Muhlenbergia porteri, Sphaeralcea ambigua</i>, and invasive exotic annuals <i>Bromus rubens</i> and <i>Erodium cicutarium</i>. Stands occur from upper bajadas near mountain slopes, volcanic domes, rolling hillslopes, to elevated mesatops and upper slopes and ridges from 810 to 1820 m elevation. Sites vary from gentle to somewhat steep (1-21°) slopes on all aspects. Soils typically range between sand and loam and are derived from a variety of substrates such as alluvium, gneiss, granodiorite, rhyolite, and sand.  Accession Code: urn:lsid:vegbank.org:commConcept:37535-{0522C3F3-B6DD-4E9D-8FB6-1DE92DB9AE67} Plot-observations of this Community Concept: 0
