Name: Picea engelmannii Swamp Forest Alliance
Reference: NatureServe Biotics 2019
Description: This alliance contains coniferous-dominated swampy riparian areas with <i>Picea engelmannii, Picea glauca</i>, and their hybrids. <i>Betula papyrifera</i> is occasionally present. Shrub layer includes <i>Alnus incana, Betula occidentalis</i>, and/or <i>Cornus sericea</i>. The herbaceous layer is dominated by the forb <i>Lysichiton americanus</i> or <i>Carex disperma, Cinna latifolia</i>, and/or <i>Athyrium filix-femina</i>. This alliance can be found on level sites that have a high water table such as adjacent to meandering streams and ponds; the water table is usually within 50 cm of the soil surface throughout the year. Standing water may be present in depressions. Soils are poorly drained and have a high organic matter content in the upper horizon. Stands are located in low-elevation (880-900 m) valleys. The vegetation in this alliance occurs in riparian areas in Montana, Wyoming and Idaho.
