Name: Picea (x albertiana, engelmannii) / Lysichiton americanus Swamp Forest
Reference: NatureServe Biotics 2019
Description: This association occurs in low-elevation valleys, from 760 to 915 m (2500-3000 feet), west of the Continental Divide in the northern Rockies. This association is found in valley bottoms, on level sites with high water tables. Sites are typically adjacent to low-gradient, meandering streams or ponds. Soils are wet throughout the year, with standing water in soil depressions; the water table surface is usually found less than 50 cm below the ground surface. Organic matter content is high, and gleying is occasionally present. Exposed rocks are not present. This is a moderately open, forested wetland association, dominated by <i>Picea engelmannii</i> or <i>Picea glauca</i>, or a hybrid of the two. Other trees present may include the conifers <i>Abies lasiocarpa, Pinus contorta</i>, or <i>Pseudotsuga menziesii</i>, but only <i>Picea</i> spp. are successful in dominating these wet sites. Small depressions with standing water are interspersed among the trees. The shrub layer is abundant and dominated by a mix of <i>Alnus incana, Betula occidentalis</i>, and <i>Cornus sericea</i>. The low, creeping shrub <i>Cornus canadensis</i> is common as well. <i>Lysichiton americanus</i> is important in the lush herbaceous layer, growing on the edge of water and on moist microsites throughout the understory. Other common herbaceous species include <i>Galium triflorum, Athyrium filix-femina</i>, and <i>Cinna latifolia</i>.
