Name: Ambrosia dumosa Desert Dwarf Scrub Alliance
Reference: NatureServe Biotics 2019
Description: This desert scrub alliance is characterized by an open dwarf-shrub layer dominated by <i>Ambrosia dumosa</i>. Other characteristic species include <i>Encelia farinosa, Eriogonum fasciculatum</i>, and <i>Ephedra nevadensis</i>. Rocky slope sites tend to contain <i>Echinocactus polycephalus, Ferocactus cylindraceus, Mammillaria</i> sp., and other cacti. Lower bajada slopes in the northern and western Mojave tend to have <i>Ericameria cooperi, Grayia spinosa, Lycium cooperi</i>, and <i>Tetradymia stenolepis</i>. This alliance is found in the Mojave, Sonoran and Colorado deserts. Sites occur on dry rocky sites that are too harsh for <i>Larrea tridentata</i> to be abundant and on sites where <i>Larrea tridentata</i> has been removed by disturbance. It also may occur in areas which sustain slightly cooler winter temperature than <i>Larrea tridentata</i>-dominated areas such as edges of mid-elevation basins in the northern and western Mojave Desert.
