Name: Lepidospartum latisquamum Shrubland
Reference: NatureServe Biotics 2019
Description: This association is currently described only from the Mojave Desert Network. Additional global information will be added as it becomes available. It is found rarely along gravelly, upper elevation washes in the southern Great Basin such as in the Cottonwood Mountains, Inyo Mountains, and Last Chance Range in Death Valley National Park, California. It also appears to occur further southwest in the Transverse Ranges of California, such as in the San Gabriel Mountains and San Bernardino Mountains, as well as further north in the White Mountains, based on details of plant specimen records in desert and desert-transition mountains of California. Elevation ranges from approximately 1850 to 1950 m, and averages 1894 m. Slopes are gentle (3-4°). This association is found primarily in intermittently flooded channel beds with variable aspect. Soils include clay loam, loamy sand, and silty clay, and are derived from sedimentary, mixed alluvium substrates, including sandstone, dolomite, limestone, and shale rocks. Vegetation forms an open shrub canopy in which the shrub cover ranges from 6 to 22%. The emergent tree layer is sparse and ranges from 0.2 to 1.2% cover, and the herb understory is variable and ranges from 0 to 1% cover. <i>Lepidospartum latisquamum</i> is the dominant and/or codominant shrub with <i>Artemisia tridentata ssp. vaseyana, Ephedra viridis, Eriogonum heermannii</i>, and <i>Purshia stansburiana</i> being characteristically present. Other shrubs often present include <i>Ericameria nauseosa, Menodora spinescens, Prunus fasciculata</i>, and <i>Symphoricarpos</i> spp. Commonly associated herbs include <i>Chaenactis</i> spp. and <i>Elymus elymoides</i>. <i>Yucca brevifolia</i> is characteristically present in the tree layer, and those sometimes present include <i>Juniperus osteosperma</i> and <i>Pinus monophylla</i>. These wash stands are diverse in shrub composition and appear adjacent to upland stands of <i>Artemisia tridentata ssp. vaseyana</i>.
