Name: Populus balsamifera ssp. trichocarpa / Cornus sericea / Carex obnupta Riparian Forest Reference: NatureServe Biotics 2019 Description: This small-patch forest community occurs on sites with strongly fluctuating water tables in coastal British Columbia and western Washington. The range of the plant community occurs in the Georgia Basin of coastal British Columbia and in the Puget Trough of Washington at elevations of 0 to 150 m. This deciduous forest has a moderate to closed canopy with a well-developed shrubby understory and a moderately well-developed herb layer, often dominated by <i>Carex obnupta</i>, and a moderately well-developed moss layer dominated by <i>Eurhynchium praelongum</i>. High cover of <i>Populus balsamifera</i> characterizes the overstory. <i>Abies grandis</i> or <i>Alnus rubra</i> often occur in smaller amounts also, and the latter may codominate locally. The subcanopy tree <i>Malus fusca</i> is frequent and contributes substantial cover. The well-developed understory is dominated by shrubs, including high cover of <i>Cornus sericea, Symphoricarpos albus</i>, and <i>Oemleria cerasiformis</i> and low to moderate cover of <i>Frangula purshiana</i>. The moderately well-developed herb layer is often dominated by high cover of <i>Carex obnupta</i>. Low to moderate cover of <i>Carex deweyana, Polystichum munitum, Rubus ursinus</i>, and <i>Maianthemum dilatatum</i> is often found in the herb layer. The moderately well-developed but floristically simple moss layer is dominated by high cover of <i>Eurhynchium praelongum</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:31746-{E80E3F83-67F4-4502-BCE5-6584BC6C036C} Plot-observations of this Community Concept: 0
