Type Concept: This plant association is described from the Snake River canyon in western Idaho from sites at 460 to 800 m (1500-2625 feet) elevation. The overstory of stands is dominated by Alnus rhombifolia; dispersed Populus balsamifera ssp. trichocarpa, Pinus ponderosa, or Prunus virginiana are often present. The shrub understory is occupied by Sambucus nigra ssp. cerulea. No other information is currently available.
