Name: Myriophyllum sibiricum Permanently Flooded Herbaceous Alliance
Reference: Western Ecology Working Group of...
Description: Vegetation types within this alliance generally occur in shallow ponds and along shores of shallow lakes, in eutrophic conditions. The ponds are typically still and shallow (up to 1.5 m or slightly more) water. Elevations range from 1500-2700 m. Nutrient-rich water (which may result from an influx of sewage, livestock waste, etc.) characterizes its environment. Surface water (often alkaline) persists throughout the growing season. Soils remain saturated even when the water level drops below the soil surface. Soil texture ranges from loamy to clay loam, and typically a clay lens is located under the pond and pond edges. Due to the anaerobic conditions, peaty soils form usually greater than 40 cm. Mottling occurs within the first 10-15 cm and gleyed soils are very common. Vegetation types within this alliance are classified as permanently flooded, temperate or subpolar, hydromorphic-rooted vegetation. Myriophyllum sibiricum dominates the forb layer with up to 70% cover. Other aquatic macrophytes include Ranunculus trichophyllus, Potamogeton spp., and Utricularia macrorhiza.
