Name: Deschampsia caespitosa Saturated Herbaceous Alliance Reference: Western Ecology Working Group of... Description: This wetland alliance occurs in subalpine meadows and alpine tundra in the Rocky Mountains and in New Jersey. In the Rocky Mountains, stands are found in shallow depressions and on flat surfaces where snow accumulates in the winter and melts relatively late in the spring. Soil texture varies among stands, but soils are poorly drained and remain saturated throughout the growing season. Topographic position accounts for the poorly drained soils. Deschampsia caespitosa and Caltha leptosepala codominate the herbaceous layer. Pedicularis groenlandica, Polygonum bistorta, and Veronica wormskjoldii and a number of Carex species are common associates. In the Kittatinny Mountains in New Jersey, similar vegetation occurs in a forb-dominated, acidic, seepage wetland community that is confined to a single location. On this site, seepage water is diverted to the surface by a clay fragipan. The herbaceous layer is dominated by Deschampsia caespitosa, Carex bromoides, Carex atlantica ssp. atlantica (= Carex atlantica var. incomperta), and Claytonia virginica var. hammondiae. Diagnostic of this wetland alliance is the perennially saturated soils dominated or codominated by the bunchgrass Deschampsia caespitosa.  Accession Code: VB.CC.19809.DESCHAMPSIACAES Plot-observations of this Community Concept: 0
