Name: Alnus incana / Spiraea douglasii Shrubland
Reference: Western Ecology Working Group of...
Description: This association occurs in Washington, Oregon and California. This riparian tall-shrub (or small-tree) community is common in eastern Oregon at elevations of 670-1740 m (2200-5700 feet). Stands are found on a variety of riparian fluvial surfaces. Soil textures vary from loam to sandy loam grading into cobbles and gravels. Soils are well drained, but remain wet-moist because of the proximity of water. The shrub canopy is dominated by <i>Alnus incana</i> (42% cover) and <i>Spiraea douglasii</i> (18% cover). Forb cover averages 29%, and is typified by <i>Maianthemum stellatum</i> (4%), <i>Galium triflorum</i> (2%), and <i>Achillea millefolium</i> (1%). Important graminoids are <i>Carex angustata (= Carex eurycarpa)</i> (5%), <i>Glyceria striata (= Glyceria elata)</i> (4%), and <i>Carex disperma</i> (3%). <i>Athyrium filix-femina</i> (2%) is also common.
