NatureServe Biotics 2019
Description:
These forests are characterized by a canopy of <i>Abies amabilis</i> and/or <i>Tsuga mertensiana</i>, with <i>Abies lasiocarpa, Picea engelmannii, Pinus albicaulis</i>, and <i>Callitropsis nootkatensis</i>. In this typically mixed forest, <i>Abies lasiocarpa</i> usually codominates the overstory. Associated shrubs are primarily <i>Vaccinium membranaceum, Vaccinium ovalifolium, Vaccinium scoparium, Quercus sadleriana, Menziesia ferruginea, Oplopanax horridus</i>, and <i>Rhododendron albiflorum</i>. The herbaceous layer is generally dominated by shade-tolerant species with northern affinities, including <i>Carex</i> spp., <i>Luzula glabrata, Chimaphila umbellata, Linnaea borealis, Cornus canadensis, Clintonia uniflora</i>, and many others. Stands typically occupy moderate to steep upper mountain slopes, extending from approximately 1200 to 1500 m in elevation. The climate is cool and wet with total annual precipitation totals generally exceeding 200 cm and deep (1-3 m) snow accumulations. This conifer forest alliance occurs in upper montane and subalpine habitats of the Pacific Northwest.
