Name: Kobresia myosuroides - Carex buxbaumii Alkaline Fen Group Reference: NatureServe Biotics 2019 Description: This group occurs infrequently throughout the Rocky Mountains from Colorado north into Canada. It is confined to specific environments defined by groundwater discharge, soil chemistry (neutral to alkaline), and peat accumulation of at least 40 cm. Vegetation is dominated by graminoids and low shrubs and includes <i>Carex buxbaumii, Carex cusickii, Carex limosa, Carex saxatilis, Carex utriculata, Kobresia myosuroides</i>, and <i>Kobresia simpliciuscula</i>. Shrubs include <i>Betula glandulosa</i> and several <i>Salix</i> spp. Fens form at low points in the landscape or on slopes where groundwater intercepts the soil surface. Groundwater inflows maintain a fairly constant water level year-round, with water at or near the surface most of the time. Constant high water levels and cold winter temperatures lead to accumulation of organic material. In addition to peat accumulation and perennially saturated soils, soil chemistry is alkaline to neutral with nutrients high in base cations. Nitrogen (N) and potassium (K) are usually still limiting plant growth in rich fens. Rich fens are strongly influenced by geology and occur where limestone, dolostone, marble or where glacially-derived materials are calcareous. The surrounding landscape may be ringed with other wetland systems, e.g., riparian shrublands, or a variety of upland systems from grasslands to forests.  Accession Code: urn:lsid:vegbank.org:commConcept:40201-{E838753E-BE5A-4628-BCA5-3FFEA2DF3D4A} Plot-observations of this Community Concept: 0
