Name: A.968
Reference: EcoArt 2002
Description: This shrubland alliance occurs adjacent to streams and rivers throughout the montane areas in the western U.S. Stands are restricted to narrow stream benches in ravines and on narrow terraces of wider valleys that are flooded for brief periods during the growing season. Soils are alluvial with little or no development. Vegetation within this alliance is characterized by a moderately dense to dense shrub layer dominated by ~Cornus sericea$. Shrub associates may include ~Salix$ spp., ~Ribes inerme, Alnus incana, Lonicera involucrata, Betula occidentalis$, and ~Acer glabrum$. Occasional ~Populus angustifolia, Pinus ponderosa, Populus deltoides$, and ~Pseudotsuga menziesii$ trees may be present. The herbaceous layer is sparse due to the dense shrub canopy. Common graminoid species are ~Phalaris arundinacea$ and ~Poa palustris$. Forb species include ~Heracleum maximum (= Heracleum lanatum)$ and ~Galium triflorum$. Diagnostic of this alliance is the dominance of ~Cornus sericea$ in the shrub layer and the presence of surface water for brief periods during the growing season.
