Name: Acer negundo - Celtis laevigata var. reticulata Woodland
Reference: Western Ecology Working Group of...
Description: This association has been described only from the Yampa and Green river corridors in Dinosaur National Monument in northwestern Colorado and adjacent eastern Utah. It may occur rarely in isolated stands in canyons throughout the southwestern U.S. Stands are found on gently to moderately angled colluvial slopes or alluvial terraces and at the base of canyon walls, high enough above the river channel so as to flood only rarely, but low enough that tree roots can still tap the water table. Elevation is below 1800 m. Nonvegetated ground cover is primarily litter with 15% large rock or gravel. Shade from canyon walls and a "mulch" of surface rock are some of the environmental factors influencing the vegetation. <i>Acer negundo</i> and <i>Celtis laevigata var. reticulata</i> codominate the tree canopy of this association, with a total canopy cover ranging from 45 to 60%. <i>Acer negundo</i> usually has higher cover than <i>Celtis laevigata var. reticulata</i>. Shrub layers are insignificant. The herbaceous layer is dominated by <i>Bromus tectorum</i> with cover ranging from 20 to 60%.
