Fraxinus latifolia - (Populus balsamifera ssp. trichocarpa) / Cornus sericea Riparian Forest
Translated Name: Oregon Ash - (Black Cottonwood) / Red-osier Dogwood Riparian Forest
Unique Identifier: CEGL003390
Classification Approach: International Vegetation Classification (IVC)
Summary: This community type occurs in the overflow plain segment of the Columbia River, from Puget Island to the gorge of Washington. It also occurs along all major streams in the southern Puget Trough and the Willamette Valley, Oregon. This community type occupies slightly higher topographic positions on floodplain terraces and natural levees along river channels. Portions receive seasonal flooding. Most of the stands, especially up-river from Longview, appear to be located above the bottomlands that would have been flooded for prolonged periods prior to flood control dams. Soils are silt-loams. This community type is characterized by the codominance of Fraxinus latifolia and Populus balsamifera ssp. trichocarpa (= Populus trichocarpa). The relative dominance of the two tree species is highly variable. Cornus sericea (= Cornus stolonifera) typically dominates the shrub layer but is sometimes replaced by Sambucus racemosa. In most stands, the understory has been degraded by grazing and introduced Phalaris arundinacea making it difficult to determine the original understory components. All stands are second-growth, except for a few scattered individual old-growth trees.
