Reference:
NatureServe Biotics 2019
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 <i>Carex lasiocarpa, Carex interior, Carex limosa, Carex livida, Trichophorum alpinum, Muhlenbergia glomerata, Rhynchospora capillacea</i>, and <i>Trichophorum cespitosum</i>. Local dominants may include <i>Carex exilis</i> and <i>Cladium mariscoides</i>. Common herbs include <i>Equisetum fluviatile, Galium labradoricum, Menyanthes trifoliata, Sarracenia purpurea, Triglochin maritima, Triantha glutinosa</i>, and <i>Utricularia intermedia</i>. Mosses include <i>Campylium stellatum, Limprichtia revolvens, Tomentypnum nitens</i>, and <i>Scorpidium scorpioides</i>. Shrub associates, though never dominant, include the dwarf-shrubs <i>Andromeda polifolia</i> and <i>Vaccinium oxycoccos</i>, and taller shrubs or scrubs such as <i>Betula pumila, Chamaedaphne calyculata, Larix laricina, Lonicera villosa, Dasiphora fruticosa ssp. floribunda, Picea mariana, Rhamnus alnifolia</i>, and <i>Rubus arcticus ssp. acaulis</i>.
