Name: Carex lachenalii - Carex capillaris - Carex illota Wet Meadow Alliance Reference: NatureServe Biotics 2019 Description: Vegetation of this alliance are alpine and subalpine seasonally flooded wet meadows dominated by <i>Carex lachenalii, Carex capillaris</i>, and/or <i>Carex illota</i>. Other graminoid species present can include <i>Juncus biglumis, Juncus triglumis</i>, and <i>Carex misandra</i>. Forbs, when present, include <i>Gentiana algida, Geum rossii, Lloydia serotina</i>, and <i>Polygonum viviparum</i>. Elevation ranges from 2300-3600 m. Occurrences are restricted to flooded marsh or lake margins, swamps, wet meadows, around frost boils and on hummocks in the Cascade Range, Sierra Nevada and Rocky Mountains. The sites are typically flat or slightly inclined, mesic to saturated, snow-covered in winter, and cool to cold in the summer. Surface water is present for extended periods during the growing season, but is absent by the end of the growing season in most years. Soils from stands in Colorado are loess, with accumulations of organic matter. The average pH of the surface horizon is 5.2. The pH increases with depth; clay and organic matter, moisture retention capacity and available water decrease sharply with depth.  Accession Code: urn:lsid:vegbank.org:commConcept:38226-{E9700B3B-5440-45F1-9EF9-A0C367BE72BE} Plot-observations of this Community Concept: 0
