Description: This alliance is reported from Montana, California, and Utah, but may occur elsewhere because the dominant species is circumboreal. Elevation ranges from sea level in coastal stands to 3235 m in the Uinta Mountains. Most stands are associated with pond and lake margins, and the vegetation typically develops floating or quaking mats. In some sites, the vegetation may occur on low-gradient inflows or outflows of ponds or lakes. California types are associated with springs and seeps. Soils are wet, organic and deep, often forming peat. The vegetation is characterized by a dense graminoid stratum that is dominated by ~Carex limosa$ with up to 90% cover. Associated graminoids include ~Carex aquatilis, Carex buxbaumii, Carex lasiocarpa, Carex livida, Carex utriculata, Eriophorum scheuchzeri$, and ~Trichophorum caespitosum (= Scirpus cespitosus)$. Forb cover is sparse, ranging from 0-30%. Species include ~Drosera linearis, Menyanthes trifoliata, Pedicularis groenlandica$, and ~Scheuchzeria palustris$. A dense layer of ~Sphagnum$ spp. may occur in some stands. Diagnostic of this herbaceous alliance is a ~Carex limosa$-dominated wetland that is flooded for extended periods during the growing season.
