Name: Tsuga mertensiana - Abies lasiocarpa / Vaccinium deliciosum - Phyllodoce empetriformis Woodland
Reference: NatureServe Biotics 2019
Description: This mountain hemlock - subalpine fir woodland of Washington and possibly British Columbia has a tree canopy that is usually dominated by <i>Abies lasiocarpa</i> with <i>Tsuga mertensiana</i> ranging from dominant to present. <i>Abies amabilis</i> is often present. <i>Callitropsis nootkatensis</i> can be present to prominent typically as a tall shrub. The shrubs <i>Vaccinium membranaceum</i> and <i>Rhododendron albiflorum</i> often occur directly under the trees. The well-developed dwarf-shrub layer is codominated by <i>Vaccinium deliciosum</i> and <i>Phyllodoce empetriformis</i>. The herb layer can include <i>Luzula glabrata var. hitchcockii, Lupinus arcticus ssp. subalpinus, Lupinus latifolius, Arnica latifolia</i>, and <i>Valeriana sitchensis</i>. This subalpine parkland association occurs above continuous forest and below upper treeline. It is absent from the driest climatic areas such as the northeast Olympics and northeastern Mount Rainier. Its typical form is a mosaic of tree clumps, small patches of forest or woodland, and dwarf-shrub openings.
