Name: A.1357
Reference: EcoArt 2002
Description: Vegetation types within this temporarily flooded, temperate or subpolar grassland alliance occur in wet meadows and margins of streams and ponds in the mountains up to timberline. Elevations range from 2400-3900 m. Sites typically are located in narrow to broad mountain meadows, usually on organic substrates, with smooth to concave surface topography. Montana sites are on rocky alpine lakeshores and streambanks and occasionally in wet alpine meadows. Soils are Histosols, especially in the wet meadow sites. Soils are typically saturated to the surface briefly during the growing season. The water table is well below the surface, thus indicating a tolerance for seasonal drying in the upper horizons. ~Carex saxatilis$ dominates a typically dense graminoid community. ~Carex aquatilis$ is commonly present and often a codominant. ~Pedicularis groenlandica$ and ~Caltha leptosepala$ are also present in most types, but cover is typically minor. ~Deschampsia caespitosa, Carex utriculata, Carex canescens$, and ~Eriophorum scheuchzeri$ may also be present, often with only scattered occurrence. ~Deschampsia caespitosa$ is a common dominant of adjacent drier communities. Associated upland forests are dominated by ~Pinus contorta$ or ~Abies lasiocarpa$.
