Description: Vegetation types within this seasonally flooded, temperate or subpolar grassland alliance occur in wet meadows and moist swales and adjacent to seeps, springs, and stream channels in the mountains and shortgrass prairie. Elevations range from 1300-2400 m. Sites range from wet meadows that are often alkaline to peat-accumulating fens. The majority of the sites are relatively flat (1-4% slope). Soils are variable. Some sites have fairly deep soils that range from heavy clays to sandy clay loams with mottling. Sites near seeps or springs have peaty soils, up to 60 cm deep. Surface water is typically present for extended periods well into the growing season. The water table is usually near the soil surface. ~Carex praegracilis$ dominates the graminoid stratum with up to 100% cover. Stands on drier sites form narrow bands with 25-30% cover. Other graminoid species include ~Calamagrostis stricta, Carex aquatilis, Carex simulata, Carex utriculata, Deschampsia caespitosa, Eleocharis palustris$, and ~Juncus balticus$. The forb stratum is present with up to 30% cover; species include ~Cicuta douglasii$ and ~Senecio hydrophilus$. Adjacent vegetation includes patches of ~Carex nebrascensis$ and ~Pascopyrum smithii (= Agropyron smithii)$ on the prairie and ~Salix$ spp. shrublands in the mountains.
