Name: Acer negundo / Disturbed Understory Riparian Woodland
Reference: NatureServe Biotics 2019
Description: This riparian association is found in the Colorado Plateau and other areas of the southwestern U.S. The tree canopy of this association is open and 5-15 m tall. The dominant tree species is <i>Acer negundo</i> alone or with other scattered trees such as <i>Acer glabrum, Juniperus osteosperma</i>, or <i>Juniperus scopulorum</i>. There is a sparse shrub layer up to 2 m tall with <i>Artemisia tridentata, Ericameria nauseosa, Fraxinus anomala, Rhus trilobata, Ribes cereum, Tamarix ramosissima</i>, and (in the south) <i>Quercus gambelii</i>. Herbaceous cover and species composition are variable. The herbaceous stratum may be sparse or dominated by native and introduced species typically found in disturbed areas. <i>Bromus tectorum</i> is common. Other typical species are <i>Heterotheca villosa, Poa pratensis, Sisymbrium altissimum, Lepidium latifolium, Taraxacum officinale</i>, and <i>Verbascum thapsus</i>. Stands occur on upper alluvial terraces below 2015 m (6600 feet) elevation. Sites are on gentle slopes or flat areas near permanent or temporary streams but are rarely flooded because of their location on high, abandoned stream terraces. Soils are usually sandy.
