Name: Thuja plicata - Pseudotsuga menziesii - Abies grandis / Mahonia nervosa / Polystichum munitum Forest Reference: NatureServe Biotics 2019 Description: This small-patch forest community occurs on gentle and middle slopes on all aspects within the Georgia Basin of British Columbia and adjacent Washington. These sites occur at elevations from 0 to 190 m. This plant community is characterized by a closed canopy of mixed conifers and a moderate shrub layer dominated by <i>Mahonia nervosa</i> and/or <i>Gaultheria shallon</i>, herb layer dominated by <i>Polystichum munitum</i>, and moss layer dominated by feathermosses. <i>Thuja plicata, Pseudotsuga menziesii</i>, and <i>Abies grandis</i> are usually present with high cover and typically codominate the overstory. The moderately well-developed shrub layer consists primarily of moderate cover of <i>Mahonia nervosa</i> and <i>Gaultheria shallon</i> together with low cover of <i>Rosa gymnocarpa</i> and <i>Vaccinium parvifolium</i>. <i>Polystichum munitum</i>, and often <i>Achlys triphylla</i> in British Columbia, dominate the moderately well-developed herb layer often with low cover of <i>Trientalis borealis, Rubus ursinus, Galium triflorum, Festuca subulata</i>, and <i>Trillium ovatum</i>. The moderately well-developed moss layer is dominated by high cover of <i>Eurhynchium oreganum</i> usually with low cover of <i>Leucolepis acanthoneuron</i> and <i>Hylocomium splendens</i>. It is distinguished from the similar but more species-poor ~<i>Pseudotsuga menziesii - (Abies grandis, Thuja plicata) / Mahonia nervosa - Gaultheria shallon</i> Forest (CEGL002845)$$ by high cover of rich-site indicator <i>Polystichum munitum</i> and other species such as <i>Tiarella trifoliata, Trillium ovatum</i>, and the moss <i>Leucolepis acanthoneuron</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:31750-{DF04A4B7-84C6-425F-BFAD-46B96CA6DFF1} Plot-observations of this Community Concept: 0
