Name: Picea sitchensis - Tsuga heterophylla / Vaccinium (alaskaense, ovalifolium) / Lysichiton americanus Swamp Forest Reference: NatureServe Biotics 2019 Description: This swamp forest is found in Alaska and British Columbia. The relatively open <i>Picea sitchensis</i> overstory is uneven-aged. <i>Lysichiton americanus</i>, the diagnostic undergrowth species, grows from the wetter microsites including standing water. Species composition on the drier hummocks is variable and includes <i>Vaccinium ovalifolium</i> or <i>Vaccinium alaskaense, Cornus canadensis, Alnus viridis ssp. sinuata, Hylocomium splendens, Rhytidiadelphus loreus</i>, and <i>Sphagnum</i> species. This association is a minor type occurring on outwash plains, floodplains, or dune edges. It often forms a mosaic within or at the edge of larger sites composed of drier <i>Picea sitchensis</i> or <i>Tsuga heterophylla</i> types. The surface topography typically consist of hummocks interspersed with small depressions containing standing water. The hummocks are either deep and somewhat poorly drained mineral soils or decaying logs and tree bases. The soils in the depressions are deep, poorly drained with moderate to thick organic layers; sites are often complexes of two or more soils.  Accession Code: urn:lsid:vegbank.org:commConcept:32148-{8D15A2B0-1D76-4AAB-B831-1E6579CF5FA3} Plot-observations of this Community Concept: 0
