Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Fremont Cottonwood / Netleaf Hackberry / Red Barberry Riparian Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This is a lowland riparian woodland known from southeastern Arizona. Elevation is at or below 1100 m (3600 feet). Stands occur in along perennial, low-gradient streams and in floodplains that are frequently flooded. Soils are derived from alluvium and vary from sandy to clayey. The vegetation is characterized by the dominance of Populus fremontii in the tree canopy, sometimes as an emergent strata. Celtis laevigata var. reticulata may codominate in the tree canopy or form a subcanopy or tall-shrub layer. Prosopis velutina is often present to codominate in the subcanopy or tall-shrub layer. Other important shrubs include Ziziphus obtusifolia and Prunus sp. that may extend into the tall-shrub layer (2-5 m tall). Baccharis sarothroides, Forestiera shrevei, and Ulmus sp. may form an open to moderately dense short-shrub layer. Mahonia haematocarpa is typically present in one of the shrub layers. The herbaceous layer is sparse to moderately dense depending on the density of the shrub layer. Associated species include Acalypha ostryifolia, Carex sp., Digitaria californica, and Leptochloa dubia. Sorghum halepense is present in disturbed stands.
