Description:
This dwarf-shrub quaking or floating bog occurs in the southern portion of the glaciated Northeast. It occupies oligotrophic, peat-accumulating basins. Dwarf-shrubs, especially Chamaedaphne calyculata, are strongly dominant with associate species including Kalmia angustifolia, Kalmia polifolia, Vaccinium oxycoccos, Gaylussacia dumosa, and Gaylussacia baccata. Associate shrubs generally occur with low cover although may be locally common. Scattered tall shrubs, such as Vaccinium corymbosum, Larix laricina, Picea mariana, and Acer rubrum, may occur, but always with low cover. Herbaceous cover is quite low but can include Carex trisperma, Pogonia ophioglossoides, Calopogon tuberosus (= Calopogon pulchellus), Eriophorum virginicum, Drosera rotundifolia, Drosera intermedia, Sarracenia purpurea, and Woodwardia virginica scattered throughout and with Carex canescens, Carex limosa, Triadenum virginicum, Utricularia cornuta, Rhynchospora alba, and sometimes Scheuchzeria palustris occurring in wetter fen windows. Edges of floating mats tend to receive more nutrient enrichment and support such species as Peltandra virginica, Decodon verticillatus, and Dulichium arundinaceum. The bryophyte layer is well-developed, dominated by Sphagnum capillifolium, Sphagnum magellanicum, Sphagnum rubellum, and Sphagnum fuscum with Sphagnum bartlettianum, Sphagnum cuspidatum, Sphagnum fallax, and Sphagnum recurvum also occurring in some examples.
