Name: Myrica gale - Chamaedaphne calyculata / Carex (lasiocarpa, utriculata) - Utricularia spp. Shrub Herbaceous Vegetation
Reference: Eastern Ecology Working Group of...
Description: This fen vegetation is found in peatlands and peaty lakesides of the northeastern United States. It occurs in acidic waters receiving weakly minerotrophic input from surface water inflow or seepage from surrounding uplands. The substrate may be flooded at high water, and remains saturated through the growing season. pH is acidic to circumneutral, 4.8-6.8. Tall, rhizomatous sedges dominate the vegetation, with shrubs often shorter than the graminoids. Bryophyte cover is variable. Scattered shrubs of <i>Alnus incana</i> and <i>Spiraea alba</i> may protrude above the graminoid cover; shorter shrubs such as <i>Myrica gale, Andromeda polifolia var. glaucophylla (= Andromeda glaucophylla), Vaccinium macrocarpon</i>, and <i>Chamaedaphne calyculata</i> grow among the sedges. The dominant sedges are usually <i>Carex lasiocarpa</i> or <i>Carex utriculata</i>; associates include <i>Carex oligosperma, Carex exilis, Carex vesicaria, Carex limosa, Carex canescens, Carex lacustris, Carex stricta</i> (non-tussock form), <i>Carex oligosperma, Rhynchospora alba, Calamagrostis canadensis, Cladium mariscoides, Eriophorum angustifolium, Eriophorum virginicum</i>, and <i>Dulichium arundinaceum</i>. Forbs include <i>Lysimachia terrestris, Triadenum virginicum, Osmunda regalis, Comarum palustre (= Potentilla palustris), Drosera intermedia, Utricularia intermedia</i>, and <i>Pogonia ophioglossoides</i>. The bryophyte layer is dominated by species of <i>Sphagnum</i>, including <i>Sphagnum fallax, Sphagnum papillosum, Sphagnum cuspidatum, Sphagnum fimbriatum, Sphagnum centrale, Sphagnum lescurii</i>, and others. This fen vegetation is distinguished by the dominance of <i>Carex lasiocarpa</i> and the absence of any richness indicators such as <i>Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda)</i>.
