Description: Vegetation in this seasonally flooded, temperate or subpolar grassland alliance occurs in mountainous regions adjacent to streams on alluvial terraces, old beaver ponds, and seeps. Elevations range from 1920-2900 m. The communities occur on gentle slopes; however, some stands in Utah are located on subirrigated sites with slopes greater than 5%. Soils are mineral with little development, and range from sands to silts and clays, although clayey surface horizons are common. Stands with sandy soils are typically subirrigated. Thin organic surface horizons may exist in stands near seeps. Water tables generally remain within the rooting zone throughout the growing season, but may be more than 1 m below the surface on drier sites. ~Carex microptera$ is the dominant graminoid. ~Carex utriculata$ and ~Carex aquatilis$ are often present on wetter sites. Other graminoids present include ~Carex praegracilis, Carex pellita (= Carex lanuginosa)$, and ~Juncus hallii$. On drier sites, ~Deschampsia caespitosa$ and ~Phleum alpinum$ are present and may codominate. Common forb species include ~Symphyotrichum foliaceum (= Aster foliaceus), Fragaria virginiana$, and ~Geum macrophyllum$. ~Salix wolfii$ is common in the short-shrub layer, but generally has a sparse cover. Adjacent riparian communities are ~Carex aquatilis, Carex utriculata$, and ~Salix wolfii$. Drier, upland communities typically are dominated by ~Deschampsia caespitosa$ or mesic forbs.
