Name: Acer negundo / Disturbed Understory Woodland
Reference: Western Ecology Working Group of...
Description: This riparian association is found in the Colorado Plateau and other areas of the southwestern U.S. 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. The tree canopy of this association is open to moderately closed and 5-15 m tall. The dominant tree species is <i>Acer negundo</i> with scattered <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>.
