Name: Carex capitata Herbaceous Alliance Reference: Western Ecology Working Group of... Description: These communities are typically located in alpine and high subalpine areas in high mountains of the Pacific Northwest. The climate is cold and snowy with a short growing season. Annual precipitation ranges from 100-250 cm annually, with the majority as winter snow. These communities typically occur on concave snowbeds, where snow melts by early summer. Upslope drainage supplies sufficient moisture to keep soils moist throughout the growing season. Elevations typically range from 2100-2400 m in the eastern Cascades. Soils are composed of varied parent materials, including granitics, pumice, and basalt, with abundant coarse fragments and organic material. These are hummocky, sod-forming, graminoid-forb communities dominated by Carex capitata along with numerous other herbaceous species. Forb and graminoid associates are diverse, and important species include Potentilla diversifolia, Potentilla flabellifolia, Festuca brachyphylla, Carex pachystachya, Carex phaeocephala, Carex scirpoidea ssp. pseudoscirpoidea (= Carex pseudoscirpoidea), Antennaria lanata, and Solidago multiradiata. Salix cascadensis is a common shrub associate. Adjacent vegetation is usually parkland or krummholz composed of Tsuga mertensiana, Pinus albicaulis, Larix lyallii, or Abies lasiocarpa, dry alpine grasslands, shrub-dominated wetlands, or bare rock and ice.  Accession Code: VB.CC.26429.CAREXCAPITATAHE Plot-observations of this Community Concept: 0
