Name: Populus tremuloides / Salix scouleriana Forest
Reference: Western Ecology Working Group of...
Description: This common deciduous forest occurs on midslopes on low to moderately steep north-, east- and south-facing aspects. Elevation ranges from 1800 to 2338 m (5800-7670 feet). Soils are variable. The primary distinguishing feature of this association is the abundance of Salix scouleriana comprising the tall-shrub layer under an exclusive canopy of Populus tremuloides. The shrub layer can be variable with high abundance of Amelanchier alnifolia or Prunus virginiana mixed in with the Salix scouleriana. Low shrubs are frequently present such as Symphoricarpos oreophilus, Sorbus scopulina, and Rosa woodsii. The herbaceous layer is also diverse with forbs dominating over graminoids. Common forbs include Osmorhiza berteroi (= Osmorhiza chilensis), Thalictrum fendleri, Ligusticum filicinum, Fragaria virginiana, Geranium viscosissimum, Delphinium X occidentale, and others. Graminoids can be numerous but not abundant, with such species as Elymus glaucus, Bromus carinatus, and Poa pratensis.
