DESCRIPTION: The vegetation is dominated by low shrubs, at least 25% cover, and a continuous covering <strong>of</strong><br />
sphagnum moss. Herbaceous cover is variable, and tree cover is less than 10%. The dominant shrub is<br />
Chamaedaphne calyculata, with associates <strong>of</strong> Andromeda polifolia, Betula pumila, Gaylussacia baccata,<br />
Nemopanthus mucronatus, Vaccinium oxycoccos, and Vaccinium macrocarpon. Characteristic herbaceous species<br />
include Calopogon tuberosus (= Calopogon pulchellus), Carex oligosperma, Drosera intermedia, Drosera rotundifolia,<br />
Eriophorum virginicum, Pogonia ophioglossoides, Rhynchospora alba, Sarracenia purpurea, and Woodwardia<br />
virginica. In stands in <strong>Ohio</strong>, Carex atlantica, Carex canescens, Carex echinata, Dulichium arundinaceum, Juncus<br />
canadensis, and Triadenum virginicum may be found. Scattered trees may be present, including Larix laricina and<br />
Picea mariana (Curtis 1959, White and Madany 1978, Homoya et al. 1985, Chapman et al. 1989, Anderson 1996,<br />
Bakowsky and Lee 1996).<br />
Stands are found in kettle lakes associated with kettle-kame-end moraine topography. In Michigan it is also reported<br />
on pitted outwash (Chapman et al. 1989). Soils are saturated peat, with acidity somewhat reduced by slightly alkaline<br />
lakewater and groundwater influences, suggestive <strong>of</strong> a "poor fen" hydrology (Curtis 1959, White and Madany 1978,<br />
Homoya et al. 1985, Chapman et al. 1989, Anderson 1996).<br />
COMMENTS: 2, MCS. Type may be very similar to <strong>the</strong> more nor<strong>the</strong>rn lea<strong>the</strong>rleaf poor fen type Chamaedaphne<br />
calyculata / Carex oligosperma / Sphagnum spp. Poor Fen Dwarf-shrubland (CEGL005277). In Ontario this type<br />
represents glaciated kettle bogs in extreme sou<strong>the</strong>rn Ontario. Schneider and Cochrane (1997) summarize current<br />
stand conditions in <strong>Ohio</strong>. Examples <strong>of</strong> <strong>the</strong> "Sphagnum bog" type in <strong>Ohio</strong> are very small (
