CEGL003423 Carex (livida, utriculata) / Sphagnum spp. Fen
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: (Livid Sedge, Northwest Territory Sedge) / Peatmoss species Fen
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association occurs in poor fens or bogs at low elevations on the western Olympic Peninsula of Washington. Soils are saturated or permanently flooded with a few centimeters of water, and are composed of sphagnum and fibrous peat, sometimes with heath peat or woody material. It occurs on gentle slopes, in basins, or on flat terraces adjacent to slow-moving streams. The vegetation is low-growing, species-rich, somewhat variable, and cover of vascular plants ranges from about 20-70%. Sphagnum spp. are always dominant, with at least 80% cover. The herb layer is usually dominated or codominated by Carex livida, Carex utriculata, Carex interior, or Sanguisorba officinalis, though it can show lack of clear dominance. The evergreen dwarf-shrub Vaccinium oxycoccos is often present and sometimes codominant. The evergreen shrubs Kalmia microphylla and Ledum groenlandicum are usually present in small amounts. The association is distinguished by the low growth habit with at least 15% cover of Carex livida or Carex utriculata, and Sphagnum spp. covering most of the surface.
