Name: Fraxinus latifolia / Carex deweyana - Urtica dioica Forest Reference: Western Ecology Working Group of... Description: 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. It was probably widespread on bottomlands between Longview and Skamania, and may have also occurred in the Willamette Valley. Soils are hydric silt loams and are subject to extended winter flooding and midsummer drying. Topography is flat with broad depressions. Historically these sites were inundated for half the summer, but now only deeper depressions retain water until late spring or early summer. <i>Fraxinus latifolia</i> is the dominant tree, with few or no <i>Populus balsamifera ssp. trichocarpa</i> present. The herb and shrub layers are sparse and reflect the long residence time of seasonal floodwater. <i>Urtica dioica, Carex leptopoda (= Carex deweyana ssp. leptopoda)</i>, and <i>Carex obnupta</i> dominate the understory.  Accession Code: VB.CC.33494.CEGL003365 Plot-observations of this Community Concept: 0
