Name: Thuja plicata - Pseudotsuga menziesii - Tsuga heterophylla / Polystichum munitum - Dryopteris expansa Forest Reference: NatureServe Biotics 2019 Description: This small-patch forest community occurs on rich, mesic or subhygric sites in coastal British Columbia at elevations from 0 to 650 m. The range of this plant community occurs at lower elevations on coastal British Columbia and north to Hardwicke Island, in lower elevation drainages of the Fraser River near Chilliwack, and in the eastern Coast Mountains. This plant community is characterized by a closed canopy with mixed conifers and a moderate shrub layer dominated by <i>Acer circinatum</i>, moderate herb layer dominated by <i>Polystichum munitum</i>, and sparse moss layer dominated by feathermosses with some leafy mosses. Overstories are closed and dominated by high cover of <i>Thuja plicata, Tsuga heterophylla</i>, and <i>Pseudotsuga menziesii</i>. The moderately well-developed shrub layer is dominated by moderate cover of <i>Acer circinatum</i> and low cover of <i>Vaccinium parvifolium</i> and regenerating <i>Thuja plicata</i> and <i>Tsuga heterophylla</i>. The moderately well-developed herb layer is dominated by low to moderate cover of <i>Polystichum munitum</i> with low cover of <i>Dryopteris expansa, Tiarella trifoliata, Rubus ursinus</i>, and <i>Pteridium aquilinum</i>. The moss layer can be sparse to moderately well-developed, with <i>Hylocomium splendens</i> and <i>Eurhynchium oreganum</i> as predominant species along with low cover of <i>Rhytidiadelphus loreus</i> and <i>Plagiomnium insigne</i>. This association is distinguished from the wetter <i>Tsuga heterophylla - Pseudotsuga menziesii - Thuja plicata / Polystichum munitum - Athyrium filix-femina</i> Forest (not in USNVC) by the high constancy of <i>Acer circinatum</i> and the lack of seepage indicator species such as <i>Rubus spectabilis</i> and <i>Athyrium filix-femina</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:31751-{FE285FE9-F53C-4EA1-B00F-7AA7970879C6} Plot-observations of this Community Concept: 0
