Common (Translated Scientific) Name: Mountain Hemlock - Pacific Silver Fir / Thinleaf Huckleberry / Sitka Valerian Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This mountain hemlock - Pacific silver fir woodland of Washington and British Columbia has a canopy that is usually codominated by Tsuga mertensiana and Abies amabilis (the latter can be absent). Occasionally, Abies lasiocarpa or Callitropsis nootkatensis are codominant. The well-developed shrub layer is dominated by Vaccinium membranaceum. Sorbus sitchensis is usually present. The short shrub Vaccinium deliciosum is often prominent. The herb layer is well-developed and dominated by Valeriana sitchensis. Veratrum viride and Arnica latifolia are usually present. This open forest or woodland association occurs at high elevations on upper slopes and ridgetops with well-drained, rocky or shallow soils in the Cascades and possibly Olympic Mountains of Washington.
