Name:
Chilopsis linearis - Fallugia paradoxa - Prunus fasciculata Desert Wash & Colluvial Slope Group
Reference:
NatureServe Biotics 2019
Description:
This group is restricted to 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. A woody layer is usually present and is typically scattered clumps to very open and may be dominated by shrubs and small trees such as <i>Acacia greggii, Brickellia laciniata, Baccharis sarothroides, Chilopsis linearis, Ephedra californica, Ericameria paniculata, Fallugia paradoxa, Forestiera pubescens, 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>, 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>Panicum bulbosum, Alopecurus aequalis</i>, or <i>Lycurus phleoides</i>. Although often dry, the intermittent fluvial processes are characteristic of this group, which are often associated with rapid sheet and gully flow. This group is restricted to drainages in upland areas or ramaderos that are intermittently flooded and occur as linear or sometimes broader braided strips within desert scrub-or desert grassland-dominated landscapes. The vegetation of desert washes is quite variable in species composition and structure, ranging from sparse and patchy to moderately dense, and typically occurs along the banks, but may occur within the channel.
