Name: Chilopsis linearis Intermittently Flooded Shrubland Alliance Reference: Western Ecology Working Group of... Description: This alliance includes shrublands occurring along ephemeral, intermittently flooded streams in the southwestern United States, dominated by Chilopsis linearis. Shrublands within this southwestern desert alliance occur within and along drainages that dissect bajadas, mesas and plains in the Chihuahuan, Sonoran, Colorado, Mojave and southern Great Basin deserts usually below 1600 m in elevation. Specific sites are known from western Texas, southern Nevada, southern California, and the Mexican state of Coahuila. They also occur in southern New Mexico and Arizona, and Sonora, Mexico. They are restricted by the arid climate to arroyo riparian zones and adjacent floodplains. The best examples of this community are in the lower portions of the arroyo where the streambed widens. This community is dependent on the intermittent flows/flooding of the channel to supplement soil moisture. In western Texas, these shrublands occur on cobble beds of intermittently flooded streams. These communities have a 2- to 5-m tall woody layer that is dominated by the xeromorphic, cold-deciduous shrub Chilopsis linearis. Other characteristic shrubs may include Acacia greggii, Baccharis salicifolia (= Baccharis glutinosa), Baccharis pteronioides, Brickellia laciniata, Fallugia paradoxa, Hymenoclea monogyra, Indigofera lindheimeriana, Platanus occidentalis, or Salix nigra. The usually sparse herbaceous layer is dominated by annual grasses such as Bouteloua barbata. In southern Nevada, stands are surrounded by Mojavean desertscrub dominated by Larrea tridentata or Coleogyne ramosissima. In western Texas, stands are surrounded by Chihuahuan desertscrub dominated by Larrea tridentata.  Accession Code: VB.CC.21597.CHILOPSISLINEAR Plot-observations of this Community Concept: 0
