Name: Bromus rubens - Erodium cicutarium - Chaenactis spp. Ruderal Desert Grassland 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 on post-burn alluvial terraces and valleys of Death Valley National Park in California and Nevada. It is found in mid to upper elevations (ranging from approximately 900-1350 m and averaging 1077 m). Slopes are gentle to somewhat steep (1-18°). It is found primarily on midslope positions at easterly to southerly aspects. Soils include clay loam to loamy sand and are derived from a variety of substrates such as alluvium and rhyolite. Vegetation forms an open to intermittent herb layer in which the herbaceous cover ranges from 3 to 53%. The tree layer is typically absent, and the shrub layer is sparse and ranges from 0.3 to 2% cover. <i>Bromus rubens, Erodium cicutarium</i>, and <i>Chaenactis</i> spp. are characteristically present and often codominant in the herbaceous layer. Other commonly associated herbs include <i>Amsinckia</i> spp., <i>Cryptantha</i> spp., <i>Dalea</i> spp., <i>Eriogonum</i> spp., <i>Eschscholzia</i> spp., <i>Mentzelia</i> spp., <i>Phacelia fremontii, Salvia columbariae</i>, and <i>Sphaeralcea ambigua</i>.
