CEGL001164 Chilopsis linearis Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Desert-willow Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This palustrine shrubland occurs along desert washes in the southwestern U.S. and northwestern Mexico. Sites are intermittently flooded drainages on alluvial fans and basins from 960-1080 m (3135-3550 feet) elevation at Buenos Aires National Wildlife Refuge. Stands in the Verde Valley at Tuzigoot National Monument occur on floodplains at around 1500 m. Substrates are generally sandy. The vegetation is characterized by a tall-shrub layer dominated by Chilopsis linearis. Acacia greggii may codominate in the tall-shrub layer, but Prosopis velutina generally has low cover (<10%). Baccharis sarothroides forms an open short-shrub layer in some stands. A sparse to moderately dense herbaceous layer is present and composed of a mixture of annual and perennial forbs and grasses. Common species include Acalypha neomexicana, Amaranthus palmeri, Boerhavia coccinea, Bouteloua aristidoides, Urochloa arizonica, Eriogonum polycladon, Gutierrezia microcephala, and Setaria spp. The exotic grass Eragrostis lehmanniana is present in some stands but at relatively low cover.
