Reference:
Eastern Ecology Working Group of...
Description:
This Atlantic white-cedar swamp occurs on the northern Coastal Plain and in areas of coastal climate (generally within 25 miles of the ocean) from New Hampshire to Delaware. It occurs in poorly-drained depressions or basins generally overlaying sand and gravel deposits. The canopy is dominated by <i>Chamaecyparis thyoides</i> or codominated with <i>Acer rubrum</i>. Less frequent canopy associates include <i>Pinus rigida, Nyssa sylvatica</i>, and sometimes <i>Tsuga canadensis</i> and <i>Pinus strobus</i>. The shrub layer is very dense and diverse with <i>Clethra alnifolia, Ilex glabra, Morella pensylvanica (= Myrica pensylvanica), Gaylussacia frondosa (= var. frondosa), Leucothoe racemosa, Rhododendron viscosum, Ilex laevigata, Ilex verticillata, Photinia melanocarpa (= Aronia melanocarpa)</i>, and <i>Vaccinium corymbosum</i>. The herbaceous layer tends to be sparse or patchy and limited to sunny openings with <i>Osmunda cinnamomea, Thelypteris palustris, Woodwardia virginica, Woodwardia areolata, Thelypteris simulata, Gaultheria procumbens, Drosera</i> spp., <i>Sarracenia purpurea, Pogonia ophioglossoides, Mitchella repens, Carex striata, Carex collinsii, Carex atlantica</i>, and <i>Toxicodendron radicans</i>. The nonvascular layer includes several species of <i>Sphagnum</i>, commonly <i>Sphagnum fallax, Sphagnum flavicomans, Sphagnum magellanicum, Sphagnum pulchrum, Sphagnum recurvum</i>, and <i>Sphagnum palustre</i>. Key diagnostic characteristics of this association are its coastal setting and the presence of Coastal Plain species such as <i>Ilex glabra, Gaylussacia frondosa, Morella pensylvanica, Leucothoe racemosa</i>, and <i>Clethra alnifolia</i>.
