Name: Fraxinus latifolia - Populus balsamifera ssp. trichocarpa / Symphoricarpos albus Riparian Forest Reference: NatureServe Biotics 2019 Description: This community type occurs along the Columbia River above Longview, Washington, as well as along other major streams and rivers in the southern Puget Trough and Willamette Valley, Oregon. It occupies drier, slightly higher portions of floodplain terraces and natural levees along river channels. Stands appear to be located above the bottomlands that would have been flooded for prolonged periods prior to flood control dams. Soils are silt-loams. Subirrigation is probably minor. The relative dominance of <i>Fraxinus latifolia</i> and <i>Populus balsamifera ssp. trichocarpa</i> is highly variable in this community type. <i>Symphoricarpos albus</i> is the dominant shrub species. In most stands, the understory has been degraded by grazing and introduced <i>Phalaris arundinacea</i> making it difficult to determine the original understory. All stands are second-growth, except for a few scattered individual old-growth trees.  Accession Code: urn:lsid:vegbank.org:commConcept:29550-{AC91136D-3D0F-46D8-B847-1926609D9391} Plot-observations of this Community Concept: 0
