Name: Alnus incana / Cornus sericea Shrubland
Reference: Western Ecology Working Group of...
Description: This riparian, tall-shrub association is present throughout Idaho and Montana, eastern Oregon and Washington, and the mountains of Colorado. It is considered a minor type throughout Utah and north-northeastern Nevada and is largely restricted to the higher more northerly mountains of California. This type is predominately present in narrow V-shaped canyons between 1219 and 2438 m (4000-8000 feet) elevation on gentle undulating, low to moderate height terraces of various aspects. Stands primarily occupy streambanks but may also be found on floodplains and alluvial bars. Soils are of a sandy loam formed by fluvial deposits. Alnus incana dominates the low tree overstory with a dense shrub layer of Cornus sericea. Common shrubs usually intermixed within this layer include Amelanchier alnifolia, Lonicera involucrata, Ribes hudsonianum, Rosa spp., Salix spp., and Symphoricarpos oreophilus. The density of the shrub layer determines the presence of the herbaceous understory. When present, common species include Agrostis stolonifera, Angelica arguta, Calamagrostis canadensis, Equisetum arvense, Galium spp. and Maianthemum stellatum (= Smilacina stellata).
