Description:
This wetland herbaceous alliance is characterized by a dense herbaceous layer dominated by <i>Glyceria borealis, Glyceria striata</i>, or <i>Glyceria grandis</i>, up to 2 m tall. Other graminoids that may be present include <i>Agrostis scabra, Carex aquatilis, Carex athrostachya, Carex nebrascensis, Carex utriculata, Carex vesicaria, Cinna latifolia, Eleocharis</i> spp., <i>Juncus</i> spp., <i>Leersia oryzoides</i>, or <i>Phalaris arundinacea</i>. A variety of forbs include <i>Bidens cernua, Cerastium</i> spp., <i>Epilobium</i> spp., <i>Epilobium hornemannii, Mentha arvensis, Mimulus guttatus, Montia chamissoi, Polygonum</i> spp., <i>Potentilla</i> spp., <i>Rumex crispus, Senecio</i> spp., <i>Solidago canadensis</i>, or <i>Veronica americana</i>. This alliance is found in the Cascade Range, Sierra Nevada, Intermountain West ranges, and Rocky Mountains. Elevation ranges from 460 to 2700 m (1500-8900 feet). Stands are seasonally or permanently flooded and occur on the margins of ponds and reservoirs and in wet meadows on floodplains of low-gradient streams, springs, sloughs, and ditches. Substrates vary from organic to fine-textured mineral soils but tend to be deep, poorly drained, alluvial soils. Mineral soils typically have a thick layer of organic muck.
