Name:

Reference:
NatureServe Biotics 2019
Description:
This macrogroup consists of variable vegetation of desert washes ranging from sparse and patchy to moderately dense, and typically occurs along the edges or in the channel bottoms. A woody layer is usually present and is typically intermittent to open and may be dominated by shrubs and small trees such as <i>Acacia greggii, Baccharis sarothroides, Bebbia juncea, Brickellia laciniata, Chilopsis linearis, Ephedra californica, Ericameria paniculata, Fallugia paradoxa, Hymenoclea salsola, Hymenoclea monogyra, Hyptis emoryi, Juglans microcarpa, Lepidospartum squamatum, Olneya tesota, Parkinsonia florida, Prosopis</i> spp., <i>Psorothamnus spinosus, Prunus fasciculata, Rhus microphylla, Salazaria mexicana, Sarcobatus vermiculatus</i>, and/or <i>Viguiera reticulata</i>. A few known herbaceous communities dominate intermittent drainages and washes with woody vegetation absent or only with scattered individuals present. Dominant species include <i>Eriogonum</i> spp., <i>Mirabilis laevis, Penstemon</i> spp., <i>Panicum bulbosum, Alopecurus aequalis</i>, or <i>Lycurus phleoides</i>. This macrogroup occurs on intermittently flooded washes or arroyos that dissect bajadas, mesas, plains and basin floors throughout the warm deserts of the western U.S. and northwestern Mexico.
