Name:
Carex lasiocarpa - Trichophorum caespitosum - Rhynchospora capillacea / Andromeda polifolia Herbaceous Vegetation
Reference:
Midwestern Ecology Working Group...
Description:
This extremely rich seepage fen is found in northern Minnesota and adjacent boreal regions in Canada. Stands occur on shallow or deep peaty soils in areas of calcareous discharge. The surface water may be circumneutral (pH 6.8-8.0), with high concentrations of dissolved salts that often form a marl precipitate. The vegetation is dominated by open sedge, rush, and moss species. The dominant graminoid species include Carex lasiocarpa, Carex interior, Carex limosa, Carex livida, Trichophorum alpinum (= Scirpus hudsonianus), Muhlenbergia glomerata, Rhynchospora capillacea, and Trichophorum caespitosum (= Scirpus cespitosus). Local dominants may include Carex exilis and Cladium mariscoides. Common herbs include Equisetum fluviatile, Galium labradoricum, Menyanthes trifoliata, Sarracenia purpurea, Triglochin maritima, Triantha glutinosa (= Tofieldia glutinosa), and Utricularia intermedia. Mosses include Campylium stellatum, Drepanocladus revolvens, Tomentypnum nitens, and Scorpidium scorpioides. Shrub associates, though never dominant, include the dwarf-shrubs Andromeda polifolia and Vaccinium oxycoccos, and taller shrubs or scrubs such as Betula pumila, Chamaedaphne calyculata, Larix laricina, Lonicera villosa, Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda), Picea mariana, Rhamnus alnifolia, and Rubus arcticus ssp. acaulis (= Rubus acaulis).
