Name: Picea sitchensis - Tsuga heterophylla / Polystichum munitum Forest
Reference:
Description: This large-patch coniferous forest community occurs on rich, fresh sites overlaying nutrient-rich bedrock types from coastal British Columbia to south coastal central Oregon. These sites occur at elevations from 0 to 650 m. This plant community occurs in mountains of the Queen Charlotte Islands, the mountains and lowlands of western and northern Vancouver Island and along the outer coast and windward slopes of the Coast Mountains and Kitimat Ranges of British Columbia, at low elevations on the western Olympic Peninsula and western Willapa Hills of Washington, along a narrow outer coastal strip in northern and central Oregon, and just barely into the northwestern Cascade Range of Washington. Soils are usually loamy to sandy and are usually derived from fluvial or colluvial materials. This large-patch coniferous forest community has a moderately closed canopy, poorly developed shrub layer dominated by regenerating <i>Tsuga heterophylla</i>, well-developed forb layer characterized by abundant <i>Polystichum munitum</i>, and moderately well-developed moss layer with variable composition. The moderately closed canopy is typically dominated by high cover of <i>Tsuga heterophylla</i> and <i>Picea sitchensis</i> (but individual stands may have more or less of each), and sometimes has low to moderate cover of <i>Thuja plicata</i>. The poorly developed shrub layer is dominated by moderate cover of regenerating <i>Tsuga heterophylla</i> and low cover of <i>Vaccinium parvifolium</i> and <i>Rubus spectabilis</i>. The well-developed forb layer is dominated by high cover of <i>Polystichum munitum</i> with low cover of <i>Blechnum spicant, Dryopteris expansa, Tiarella trifoliata</i>, and <i>Athyrium filix-femina</i>. The variable, moderately developed moss layer has low to moderate cover of <i>Rhytidiadelphus loreus, Eurhynchium oreganum, Hylocomium splendens</i>, and <i>Plagiothecium undulatum</i>.
