Name: Picea sitchensis / Trisetum canescens Forest Reference: NatureServe Biotics 2019 Description: This linear floodplain community occurs on middle fluvial benches along rivers of coastal British Columbia. These sites may occur at elevations from 0 to 600 m along rivers that flood annually and have prolonged elevated water tables during the growing season. This plant community has a moderately open canopy dominated by <i>Picea sitchensis</i>, poorly developed shrub layer dominated by regenerating conifers, a species-rich herb layer, and a well-developed moss layer with mixed feathermosses and leafy mosses. <i>Tsuga heterophylla</i> commonly occurs with moderate cover, and <i>Alnus rubra</i> is consistently present, usually with low cover. Regenerating conifers, such as <i>Tsuga heterophylla</i> and <i>Picea sitchensis</i>, are typically in the shrub layer as are <i>Rubus spectabilis</i> and sometimes <i>Vaccinium parvifolium</i> at low cover. The herb layer is species-rich with numerous fern, graminoid and lily species but none with very high constancy. A moderate to high cover of <i>Elymus hirsutus</i> with moderate cover of <i>Trisetum canescens</i> are usually present, with low to moderate cover of <i>Athyrium filix-femina, Osmorhiza purpurea</i>, and <i>Gymnocarpium dryopteris</i>. <i>Hylocomium splendens</i> dominates the high bryophyte cover, along with low to moderate amounts of <i>Rhytidiadelphus loreus</i> and <i>Conocephalum salebrosum</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:31726-{60A0C074-ADBC-4AFE-96BD-575BDA6A19FE} Plot-observations of this Community Concept: 0
