Name: Acer negundo / Rhus trilobata Riparian Woodland
Reference: NatureServe Biotics 2019
Description: This box-elder woodland association is currently only known from Dinosaur National Monument in Colorado and Capitol Reef National Park in Utah, and the following description is based on occurrences there. Additional global information will be added as it becomes available. At Dinosaur, this association occurs in a spring seep on a moderately angled, northwest-facing, concave slope in the Round Valley Formation at elevations below 1800 m. The nonvegetated ground cover is primarily litter, with scattered large rocks and patches of bedrock. Soil texture is loamy sand. At Capitol Reef, it is found tucked into an alcove at the head of a tributary canyon on a steep colluvial slope at 1875 m elevation. Large colluvial boulders cover most of the unvegetated surface, with minor cover by bare soil and litter. The soil is coarse-textured and derived from underlying Chinle shale and Wingate sandstone colluvium. <i>Acer negundo</i> forms a canopy layer between 5 and 10 m high with 15-20% cover. <i>Rhus trilobata</i> and <i>Fraxinus anomala</i> dominate the somewhat open shrub layer 2-5m tall. Other shrubs at Capitol Reef include <i>Ephedra viridis, Amelanchier utahensis</i>, and <i>Mahonia repens</i> with minimal cover. At Dinosaur, <i>Amelanchier utahensis</i> and <i>Salix exigua</i> occur with minimal cover. Species codominating the herbaceous layer are <i>Clematis ligusticifolia, Solidago canadensis, Lactuca serriola</i>, and <i>Equisetum laevigatum</i>, totaling more than 20% cover. Some graminoid species with low cover include <i>Pascopyrum smithii, Piptatheropsis micrantha</i>, and <i>Poa pratensis</i>.
