Name: A.1445
Reference: EcoArt 2002
Description: The vegetation in this alliance occurs in wetlands along pond and lake margins and low-gradient streams in the northwestern United States. Stands are located between 670-1810 m elevation. Stands are found on level sites in standing water. Water is present above the soil surface throughout the summer. Soils are poorly to very poorly drained and vary from mineral to organic. Mineral soils usually have a thick layer of organic matter in the upper horizon. Species diversity is low due to the wet conditions. ~Glyceria borealis$ generally forms monotypic stands with 30-90% cover. Other graminoids that may be present include ~Eleocharis acicularis, Eleocharis palustris$, and ~Glyceria striata (= Glyceria elata)$. ~Ranunculus aquatilis$ and ~Sparganium angustifolium$ are occasional forb associates.
