Common (Translated Scientific) Name: Box-elder - Knowlton''s Hophornbeam Riparian Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This riparian woodland association is known from Capitol Reef National Park in southern Utah and this summary is derived from a plot sampled there in 1988. Total vegetation cover is in excess of 100% in this multi-layered stand. The vegetation is characterized by a relatively closed canopy of Acer negundo and Ostrya knowltonii trees that each range in cover from 51 to 75%. The associated tree canopy provides moderate cover and includes Celtis laevigata. The tall-shrub layer is low in terms of species composition, provides moderate to high cover, and includes Frangula betulifolia and Quercus gambelii. Short and dwarf-shrubs are low in terms of species composition, provide sparse cover, and include Brickellia longifolia and Mahonia fremontii. The herbaceous layer is low in terms of species diversity and provides sparse to moderate cover. Graminoids include Elymus canadensis and Poa fendleriana. Forbs include the fern-ally Equisetum hyemale. The stand occurs on a sandy bench adjacent to a perennial stream. The site slopes gently (3°) to the northeast at 1220 m elevation. The soil is derived from alluvium.
