Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Box-elder / Gambel Oak Riparian Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This is a riparian woodland found in scattered locations on the Colorado Plateau. The vegetation is characterized by an open to moderately dense tree canopy of Acer negundo and Quercus gambelii. Occasional emergent Pseudotsuga menziesii trees or subcanopy Juniperus scopulorum may be present. The understory is typically sparse and variable in species composition. Tall, short, and dwarf-shrubs contribute low cover and include Celtis laevigata var. reticulata, Cornus sericea, Fendlerella utahensis, Holodiscus dumosus, Mahonia repens, Rhus trilobata, Ribes cereum, Ribes inerme, and Prunus virginiana. The herbaceous layer is sparse and low in species diversity. Species include Maianthemum stellatum, Piptatheropsis micrantha, Arabis sp., Brickellia grandiflora, Solidago canadensis, and Artemisia michauxiana. This woodland association is known from the Gunnison River in Curecanti National Recreation Area, and on seeps and streams in Glen Canyon National Recreation Area. Stands occur in riparian sites and springs and seeps with natural or human disturbance, including constructed roadway fill slopes and rockfall or talus from adjacent cliffs. Sites are steep (75% slopes), occur between 2032 and 2073 m elevation, and are oriented to northeastern and southern aspects. The unvegetated surface has high cover of bedrock, large and small rocks, and low to moderate cover of litter. Soil is not present in the rockfill and rockfall substrate in the sampled stands.
