Name: Abies grandis / Holodiscus discolor Forest
Reference: Western Ecology Working Group of...
Description: This is an evergreen conifer forest association restricted to the eastern Cascades near the Columbia River gorge. These are mostly snow free sites generally found on exposed, south-facing slopes or ridgetops between 2500-4000 feet elevation. The name of the type reflects its potential vegetation. The existing vegetation is dominated by Pseudotsuga menziesii often with Abies grandis in the main canopy. Pinus ponderosa can be important in some stands, and Quercus garryana and Larix occidentalis can be present. The tree canopy is mostly open and could be considered a woodland in some stands. The undergrowth is characterized by a mid to tall-shrub layer. Holodiscus discolor and Rosa gymnocarpa shrubs are always present and often with high cover. Symphoricarpos mollis, Corylus cornuta and Acer circinatum shrubs are present and sometimes abundant. The herbaceous layer is patchy and dominated by forbs, primarily Trientalis borealis ssp. latifolia (= Trientalis latifolia), Moehringia macrophylla (= Arenaria macrophylla), or Achlys triphylla.
