Name: Oenanthe sarmentosa Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: From Christy (2004): This herbaceous vegetation occurs from Oregon to British Columbia at 152 to 715 m (500-2340 feet) elevation. Habitat is muddy openings in forested wetland (swamp), marsh, or shrub-swamp. Soils are seasonally flooded to perennially saturated loam. <i>Oenanthe sarmentosa</i> typically forms stands in muddy openings in both deciduous and coniferous swamp and is most common at lower elevations. <i>Alnus rubra</i> and <i>Fraxinus latifolia</i> are the primary deciduous species, and <i>Thuja plicata</i> and <i>Picea sitchensis</i> are the primary conifers, but none of these occur with much constancy or cover and are mostly peripheral to the wetland. Shrubs are also scarce, with <i>Salix sitchensis</i> being the most common one in sampled plots. The herb layer may be diverse, and over 40 species are recorded here, but most of them occur with low constancy and cover. <i>Oenanthe sarmentosa</i> is the primary species with average cover of 68% and a range of 40-99%. Other species with significant patches include <i>Callitriche heterophylla, Typha latifolia, Eleocharis palustris, Ranunculus uncinatus</i>, and <i>Lysichiton americanus</i>. Stands are usually flooded early in the season and dry down in summer, but the soil usually remains moist.  Accession Code: VB.CC.33582.CEGL003319 Plot-observations of this Community Concept: 0
