Description:
This association is an intermediate fen overlying deep peat accumulations of lakes and other depressions in the Great Lakes region east to the northeastern United States. It is characterized by rhizomatous sedges that form a mat, with variable shrub cover. Typical sedges include Carex lasiocarpa, Carex prairea, Carex leptalea, Carex stricta (= var. strictior), Carex buxbaumii, Carex flava, Carex cryptolepis, Carex lacustris, Carex livida, Carex aquatilis, Cladium mariscoides, Trichophorum alpinum (= Eriophorum alpinum), Eleocharis elliptica, as well as Vaccinium macrocarpon and Vaccinium oxycoccos. Other herbaceous associates include Carex rostrata, Carex trisperma, Eleocharis rostellata, Muhlenbergia glomerata, Rhynchospora alba, Schoenoplectus acutus (= Scirpus acutus), Typha latifolia, Doellingeria umbellata (= Aster umbellatus), Drosera rotundifolia, Iris versicolor, Osmunda regalis, Parnassia glauca, Pogonia ophioglossoides, and Thelypteris palustris. Shrubs are generally confined to hummocks, but cover varies among occurrences and can exceed 25%. Characteristic species include Myrica gale, Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda), Betula pumila, Salix candida, Rhamnus alnifolia, Alnus spp., and Cornus sericea. Larix laricina may occur as scattered individuals atop hummocks. Hollows and channels often support Utricularia intermedia, Utricularia gibba, Menyanthes trifoliata, and Lobelia kalmii. Other herbs include Symphyotrichum boreale (= Aster borealis) and Sarracenia purpurea. Characteristic mosses include Campylium stellatum, Drepanocladus revolvens, Scorpidium scorpioides, and Tomentypnum nitens. Sphagnum spp. may be absent or are minor components. When present, species include the more minerotrophic Sphagnum contortum, Sphagnum warnstorfii, and Sphagnum teres. Diagnostic species include Dasiphora fruticosa ssp. floribunda and Myrica gale, and the mixture of brown mosses and minerotrophic Sphagnum mosses.
