Hierarchy Level:  Association

Type Concept: This association has only been described from Zion National Park, Utah. Additional global information will be added as it becomes available. Vegetation structure and cover in this association are variable. Populus fremontii may be present as young trees contributing to the tall-shrub layer, codominated by riparian shrubs Betula occidentalis and Salix spp. In some cases, Populus fremontii or Juniperus scopulorum may occur as mature trees with a canopy cover of 5-20%. Betula occidentalis dominates the shrub layer (10-40% cover) accompanied by various shrubs of inconsistent frequency depending on the adjacent upland vegetation. Most frequently occurring or characteristic shrubs of this association are Salix spp. and Rosa woodsii. The herbaceous layer has variable composition, with average cover of 30% and relatively tall structure. This may not be true where recreational trails intersect streambanks and the vegetation is trampled. Common herbaceous species include Agrostis stolonifera, Poa pratensis, and Maianthemum stellatum. Elevation for this association is 1675 to 1830 m (5500-6000 feet), but it does occur at lower elevations if the site is shaded and north-facing. It occurs on flat to gentle sloping streambanks and benches on sandy loam soils.
