Name: Senna armata - Hymenoclea salsola Desert Wash Shrubland
Reference: NatureServe Biotics 2019
Description: This desert wash shrubland association is common in both the Mojave Desert of California and Nevada and the Sonoran Desert of California. It has a sparse to open or intermittent shrub layer (4-29% cover) dominated or codominated by <i>Senna armata</i> with other shrubs, especially <i>Hymenoclea salsola</i> and/or <i>Larrea tridentata</i>. Other shrubs often present include <i>Acamptopappus sphaerocephalus, Ambrosia dumosa, Cylindropuntia</i> spp., <i>Ephedra californica, Eriogonum plumatella, Krameria grayi, Lycium andersonii, Psorothamnus fremontii, Salazaria mexicana, Thamnosma montana</i>, and <i>Yucca schidigera</i>. Herbaceous cover is variable and ranges from 0-40% cover. Common species are <i>Amsinckia</i> spp., <i>Cryptantha</i> spp., <i>Salvia columbariae</i>, and exotic species <i>Bromus rubens, Erodium cicutarium</i>, or <i>Schismus</i> spp. with <i>Bromus rubens</i> often dominating disturbed sites. Occasional emergent <i>Yucca brevifolia</i> trees may be present with sparse cover (&lt;7%). Stands generally occur along, but slightly above, drainage corridors along arroyos and washes on flats and gently sloping (1-7°) alluvial fans and upper bajada pediment surfaces at mid to upper elevations. Elevations range from 600 to 1300 m. Substrates are often gravelly, course-textured alluvial soils derived from a variety of substrates such as granite, gneiss, and tephrite.
