Western Ecology Working Group of...
Description:
This shrubland alliance of the arid Southwest is found on rarely flooded, low-gradient deposits along streams. Substrates are usually rocky with little soil. Elevations range from sea level to 1800 m. Annual precipitation is quite variable and episodic, but rarely exceeds 30 cm. Summer temperatures are very hot, and some areas in the Mojave may exceed 30 degrees Celsius for many days in the summer. Stands of this desert streamside shrubland contain Lepidospartum squamatum as a dominant or important species in the shrub layer. Other shrubs present may include Rhus trilobata, Artemisia tridentata, Artemisia californica, Acacia greggii, Cercocarpus montanus var. glaber, Cleome isomeris (= Isomeris arborea), Encelia farinosa, Eriogonum fasciculatum, Hymenoclea salsola, Yucca whipplei, Lotus scoparius, Eriodictyon crassifolium, Baccharis salicifolia, Toxicodendron diversilobum, Opuntia spp., and Rhus ovata. Emergent individuals of Juniperus californica, Platanus racemosa, Juglans californica, Populus fremontii, Malosma laurina, Rhus integrifolia, and Sambucus mexicana may be present. Two rare forbs, Dodecahema leptoceras and Eriastrum densifolium ssp. sanctorum, are often associated with stands of this alliance.
