Name: Populus balsamifera ssp. trichocarpa / Salix lucida ssp. caudata Woodland Reference: Western Ecology Working Group of... Description: This association is known from scattered locations in the Blue Mountains of eastern Oregon, Washington and adjacent west-central and southwestern Idaho. The association occurs between 915 and 1372 m (3000-4500 feet) elevation on alluvial bars and abandoned channels of low-gradient, narrow streams to broad rivers (i.e., stream orders 3 and 4). The association is most often expressed in an early-seral state characterized by abundant Populus balsamifera ssp. trichocarpa seedlings and saplings and large areas of exposed coarse alluvial deposits. However, stands with mature overstory Populus balsamifera ssp. trichocarpa trees also occur. Total Populus balsamifera ssp. trichocarpa cover typically ranges from about 20-70%, while Salix lucida ssp. caudata forms a tall-shrub layer with 20-60% cover. A variety of woody species, such as other Salix species and conifer seedlings, are usually present, but all have low cover. This association is heavily influenced by annual cycles of flooding, scouring, and ice disturbance. As a result, total herbaceous cover is low and characterized by pioneering, often exotic, species. The most important understory herbaceous species is Poa pratensis, although the native grass Elymus glaucus and colonizing forbs, such as Achillea millefolium, Solidago canadensis, and Taraxacum officinale, are also commonly encountered.  Accession Code: VB.CC.21378.POPULUSBALSAMIF Plot-observations of this Community Concept: 0
