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 predominantly 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. <i>Alnus incana</i> dominates the low tree overstory with a dense shrub layer of <i>Cornus sericea</i>. Common shrubs usually intermixed within this layer include <i>Amelanchier alnifolia, Lonicera involucrata, Ribes hudsonianum, Rosa</i> spp., <i>Salix</i> spp., and <i>Symphoricarpos oreophilus</i>. The density of the shrub layer determines the presence of the herbaceous understory. When present, common species include <i>Agrostis stolonifera, Angelica arguta, Calamagrostis canadensis, Equisetum arvense, Galium</i> spp. and <i>Maianthemum stellatum (= Smilacina stellata)</i>.
