CEGL000641 Fraxinus latifolia - Populus balsamifera ssp. trichocarpa / Symphoricarpos albus Riparian Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Oregon Ash - Black Cottonwood / Common Snowberry Riparian Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: 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 Fraxinus latifolia and Populus balsamifera ssp. trichocarpa is highly variable in this community type. Symphoricarpos albus is the dominant shrub species. In most stands, the understory has been degraded by grazing and introduced Phalaris arundinacea making it difficult to determine the original understory. All stands are second-growth, except for a few scattered individual old-growth trees.

Classification Comments: This community type occurs on sites drier than those occupied by ~Fraxinus latifolia - (Populus balsamifera ssp. trichocarpa) / Cornus sericea Riparian Forest (CEGL003390)$$. It is very similar to the Fraxinus latifolia / Symphoricarpos albus community type of the northern Puget Trough region (Frenkel and Heinitz 1987).
