Name: Abies lasiocarpa / Valeriana sitchensis - Luzula glabrata Forest
Reference: NatureServe Biotics 2019
Description: This association occurs only in the Cascade Range and Olympic Mountains of Washington at elevations of 1400-2000 m. It is most common in relatively dry climatic zones for western Washington, and especially in the rainshadow of major volcanoes. Sites have well-drained soils and southern aspects. This is a needle-leaved evergreen conifer forest or woodland of relatively short stature. <i>Abies lasiocarpa</i> is always dominant (mean cover 65%). Small amounts of <i>Tsuga mertensiana</i> or <i>Abies amabilis</i> may sometimes occur in the tree regeneration layer. The relatively lush herbaceous understory is dominated by the forb <i>Valeriana sitchensis</i> and typically also the graminoid <i>Luzula glabrata var. hitchcockii</i>. The dwarf-shrub <i>Vaccinium deliciosum</i> is usually also present (mean cover 10%). Other frequent understory species that occur in low abundance are <i>Arnica latifolia, Rubus lasiococcus, Veratrum viride, Viola orbiculata, Polygonum bistortoides, Lupinus arcticus ssp. subalpinus, Polemonium pulcherrimum, Pedicularis racemosa</i>, and <i>Ligusticum grayi</i>. This association is distinguished from similar associations by &gt;3% cover of <i>Valeriana sitchensis</i> and the presence of <i>Vaccinium deliciosum</i>, along with little to no <i>Abies amabilis, Tsuga heterophylla, Tsuga mertensiana, Rhododendron albiflorum</i> (&lt;10%), <i>Vaccinium membranaceum</i> (&lt;5%), <i>Vaccinium scoparium</i>, or <i>Phyllodoce empetriformis</i>.
