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 Alnus incana (42% cover) and Spiraea douglasii (18% cover). Forb cover averages 29%, and is typified by Maianthemum stellatum (4%), Galium triflorum (2%), and Achillea millefolium (1%). Important graminoids are Carex angustata (= Carex eurycarpa) (5%), Glyceria striata (= Glyceria elata) (4%), and Carex disperma (3%). Athyrium filix-femina (2%) is also common.  Accession Code: VB.CC.24646.ALNUSINCANASPIR Plot-observations of this Community Concept: 0
