Name: Populus balsamifera ssp. trichocarpa / Oplopanax horridus - Acer glabrum Forest
Reference: Western Ecology Working Group of...
Description: This minor streambank forest occurs in narrow, very steep valleys along perennial and ephemeral streams between 793 and 1128 m (2600-3700 feet) elevation in northeast Washington. Sites are typically cold and wet, along A or intermittent channels on streambanks. Populus balsamifera ssp. trichocarpa dominates an open overstory occasionally with other hardwoods, Populus tremuloides or Betula papyrifera, but is more frequently associated with conifers, Pseudotsuga menziesii or Thuja plicata with low cover. Oplopanax horridus dominates the shrub layer and may codominate with Acer glabrum var. douglasii. Either Alnus incana ssp. tenuifolia or Philadelphus lewisii may be present. Forb cover is low and is composed of species such as Streptopus amplexifolius, Viola glabella, Prosartes hookeri (= Disporum hookeri), or Actaea rubra. Graminoids are unusual, although Cinna latifolia is often present. Athyrium filix-femina is usually present in low cover along with other ferns.
