Description:
This widespread alliance occurs in the Mojave, Sonoran and Colorado deserts and extends into the transition zone with the Great Basin. The vegetation is characterized by an open, xeromorphic shrub layer dominated by <i>Larrea tridentata, Encelia farinosa, Fouquieria splendens</i>, or <i>Nolina bigelovii</i>. Other desert shrubs and dwarf-shrubs may be present to codominant, including <i>Agave deserti, Ambrosia dumosa, Bebbia juncea, Eriogonum fasciculatum, Fagonia laevis, Ferocactus cylindraceus, Grayia spinosa, Krameria grayi, Lycium andersonii, Opuntia basilaris, Cylindropuntia bigelovii</i>, and <i>Peucephyllum schottii</i>. The herbaceous layer is typically sparse with scattered <i>Dasyochloa pulchella, Pleurocoronis pluriseta</i>, or <i>Stephanomeria pauciflora</i>. Abundant annuals such as <i>Eriogonum inflatum</i> may be seasonally abundant. Stands occur on alluvial fans, bajadas, upland slopes and minor washes. Sites are gentle to moderately sloping. Substrates are typically well-drained, rocky soils derived from colluvium or alluvium and/or with a pavement surface.
