Name: Picea sitchensis / Rubus spectabilis Mesic Forest Alliance
Reference: NatureServe Biotics 2019
Description: This alliance consists of tall conifer forests of the Pacific Northwest dominated by <i>Picea sitchensis</i>, often mixed with <i>Tsuga heterophylla</i> and other conifers. Soils are subirrigated, well-oxygenated and wet but not saturated. Wet indicator species such as <i>Oplopanax horridus</i> and <i>Rubus spectabilis</i> often form the understory shrub canopy. The herbaceous layer is dominated by mesic, shade-tolerant ferns and forbs such as <i>Athyrium filix-femina, Blechnum spicant, Maianthemum dilatatum, Oxalis oregana</i>, and <i>Polystichum munitum</i>. Mosses and lichens are abundant on logs, snags, trees, or the ground surface. Sites have subhydric, water-receiving, and poorly drained soils. This conifer forest alliance is found within the maritime climate-influenced region of the Pacific Northwest, from northern California to British Columbia and possibly southern Alaska, usually within 50 km of tidewater and below 1000 m in elevation. Stands typically occur on coastal terraces, but extend up river valleys and seaward slopes of coastal mountains. Stands occur on moderate to steep slopes with shallow to moderately deep soils.
