Name: Cornus sericea Temporarily Flooded Shrubland Alliance
Reference: Western Ecology Working Group of...
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.
