Name: Populus balsamifera ssp. trichocarpa / Mixed Herbs Forest Reference: Western Ecology Working Group of... Description: This cold-deciduous riparian forest occurs in lower mountains and foothills at 610 to 2013 m (2000-6591 feet) elevation, on alluvial terraces and floodplains of major and minor rivers and streams. Soils are poorly developed, loamy to cobbly Entisols. It is thought to be a grazing-induced type; the trees are mature and the herbaceous layer predominantly dominated by non-native graminoid species. The canopy cover is Populus balsamifera ssp. trichocarpa (=Populus trichocarpa) with 30-60% cover. There are very few shrubs and, if present, do not form a stratum layer. The herbaceous layer is dominated by either non-native graminoids or increaser species such as Phleum pratense, Poa pratensis, Bromus vulgaris, and Elymus glaucus. Forbs are in low abundance and are also dominated by increaser species.  Accession Code: VB.CC.27970.POPULUSBALSAMIF Plot-observations of this Community Concept: 0
