Name: Tsuga mertensiana - Chamaecyparis nootkatensis / Calamagrostis nutkaensis - Maianthemum dilatatum Woodland
Reference:
Description: This association is located within a subalpine Wet Hypermaritime Mountain Hemlock Windward Variant (MHwh1) along the outer coast between a potential elevational range of 500 to 1100 m above sea level, from Rivers Inlet beyond northern Vancouver Island northward to Portland Canal, and including the windward Queen Charlotte Islands. This community is located on moderately steep upper to lower slopes on shallow mineral soils receiving abundant seepage. This moderately productive subalpine community has the most productive forest in the MHwh1. <i>Chamaecyparis nootkatensis (= Callitropsis nootkatensis)</i> dominates the well-developed but somewhat scrubby canopy, with variable amounts of <i>Tsuga mertensiana</i>. The shrub layer has sparse to moderate cover and includes mainly the following conifers: <i>Chamaecyparis nootkatensis, Tsuga heterophylla, Thuja plicata</i>, and <i>Tsuga mertensiana</i>. Species in the lightly developed herb layer include <i>Calamagrostis nutkaensis, Lycopodium clavatum, Huperzia haleakalae, Blechnum spicant</i>, and <i>Veratrum viride</i>. Common species in the well-developed moss layer are <i>Scapania</i> spp., <i>Rhytidiadelphus loreus, Hylocomium splendens</i>, and <i>Dicranum majus</i>. Species diagnostic of this community include a scattered coverage of richer site indicators such as <i>Maianthemum dilatatum, Veratrum viride</i>, and <i>Streptopus lanceolatus</i>. A number of species which should be either absent or of insignificant cover include <i>Caltha leptosepala, Nephrophyllidium crista-galli (= Fauria crista-galli), Lysichiton americanus</i>, and <i>Carex</i> spp.
