CEGL003408 Populus balsamifera ssp. trichocarpa / Cornus sericea / Impatiens capensis Riparian Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Black Cottonwood / Red-osier Dogwood / Orange Jewelweed Riparian Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This mid-seral association occurs on floodplains along the middle reaches of the lower Columbia River in Oregon and Washington, and perhaps other large rivers in western Washington. Soils are anoxic silt loams and are subject to daily freshwater tidal inundation and seasonal riparian flooding. Stands are laced with dendritic tidal creeks and sloughs that enable daily tidal flooding into the interior of stands. Topography is flat to undulating, with local microrelief caused by logs, stumps, and soil interspersed among seasonally to permanently flooded pools. Populus balsamifera ssp. trichocarpa is the dominant and often the only tree, with lesser amounts of Salix lucida ssp. lasiandra and Fraxinus latifolia. The often nearly impenetrable shrub layer is dominated by Cornus sericea, Rubus spectabilis, and Rubus ursinus. The somewhat sparse herb layer is dominated by Impatiens capensis, sometimes codominated by Carex leptopoda or Lysichiton americanus.

Floristics: Populus balsamifera ssp. trichocarpa is the dominant and often the only tree, with lesser amounts of Salix lucida ssp. lasiandra and Fraxinus latifolia. The often nearly impenetrable shrub layer is dominated by Cornus sericea, Rubus spectabilis, and Rubus ursinus. The somewhat sparse herb layer is dominated by Impatiens capensis, sometimes codominated by Carex leptopoda (= Carex deweyana ssp. leptopoda) or Lysichiton americanus.

Stands are laced with dendritic tidal creeks and sloughs that enable daily tidal flooding into the interior of stands. Topography is flat to undulating, with local microrelief caused by logs, stumps, and soil interspersed among seasonally to permanently flooded pools.
Geographic Range: This association is thought to be centered along the lower Columbia River in Oregon and Washington, and perhaps some of the larger rivers in western Washington.
