Name: Abies lasiocarpa / Vaccinium membranaceum / Valeriana sitchensis Forest
Reference: NatureServe Biotics 2019
Description: This association occurs in the Cascades and in the northeastern Olympic Mountains at relatively high elevations and usually in relatively dry climatic zones. Sites have well-drained soils and usually southern aspects. <i>Abies lasiocarpa</i> dominates or codominates in a forest with a semi-open to closed tree canopy. <i>Abies amabilis</i> is usually present as the dominant regenerating tree and occasionally is codominant in the canopy. <i>Picea engelmannii</i> is sometimes prominent to codominant. The shrub layer is typically moderate in density and dominated by <i>Vaccinium membranaceum</i>. <i>Sorbus sitchensis</i> and <i>Vaccinium deliciosum</i> are frequent. Occasionally shrubs are only sparsely represented. The well-developed, diverse, and variable herbaceous layer almost always has <i>Valeriana sitchensis</i> prominent to codominant. <i>Rubus lasiococcus, Arnica latifolia</i>, and <i>Veratrum viride</i> are usually present to codominant. <i>Clintonia uniflora, Rubus pedatus, Tiarella trifoliata, Luzula glabrata var. hitchcockii</i>, and <i>Erythronium montanum</i> are less frequent but can be prominent to codominant.
