Name: Carex duriuscula Herbaceous Alliance Reference: Western Ecology Working Group of... Description: Vegetation types within this short sod, temperate or subpolar grassland alliance are common and often locally abundant on the Great Plains and in the foothills of the eastern Rocky Mountains. Elevations range from 1200-2400 m (occasionally up to 3000 m). Types occur in open parks of the foothill and montane zones on flat or gentle slopes. Typically they are one of the early communities to develop on 'rock-wash' fans that exit from canyons. Additionally, types are known from mountain tops and slopes in the alpine zone. All types occur on coarse sandy and gravelly soil lacking in humus. They are dominated by Carex duriuscula. Poa secunda often is a codominant in the graminoid layer. Other associated graminoids can include Koeleria macrantha, Poa palustris, and Festuca saximontana. Commonly occurring forbs include Artemisia frigida, Artemisia campestris, Cryptantha virgata, Achillea millefolium, and Gaillardia aristata, and the cacti Opuntia polyacantha. Selaginella densa commonly occurs in the fern stratum, especially in the rock-wash communities. Information on adjacent communities is not available.  Accession Code: VB.CC.18243.CAREXDURIUSCULA Plot-observations of this Community Concept: 0
