Name: Carex breweri Herbaceous Alliance Reference: Western Ecology Working Group of... Description: The vegetation in this alliance occurs in alpine and subalpine areas in high mountains of the Pacific Coast. Elevations range from 1700-2200 m. The climate is cold and snowy with severe winds, late-lying snow, and a short growing season. Annual precipitation ranges from over 250 cm near the Cascade crest to less than 100 cm farther east in the Cascades and in the Sierra Nevada of California. The vegetation typically occurs on concave snowbeds, which are well-drained. Snow melts by late July and soils dry thoroughly by late summer. Soils are composed of varied parent materials, including granitics, pumice, and basalt, with abundant coarse fragments. Plant associations in this alliance are dominated by Carex breweri. Xeric graminoids are the most common associates and may codominate stands. Danthonia intermedia is especially important in the northeastern Cascades, and Poa nervosa becomes important in the Sierra Nevada alpine. Other graminoid associates include Carex scirpoidea ssp. pseudoscirpoidea, Carex nardina, and Carex phaeocephala. Forb associates include Lupinus sellulus var. lobbii, Erigeron aureus, Antennaria lanata, and Solidago multiradiata. Adjacent vegetation is usually parkland or krummholz composed of Tsuga mertensiana, Pinus albicaulis, Larix lyallii, or Abies lasiocarpa, dry alpine grasslands, sedge- or shrub-dominated wetlands, or bare rock and ice.  Accession Code: VB.CC.18209.CAREXBREWERIHER Plot-observations of this Community Concept: 0
