CEGL006188 Chamaecyparis thyoides / Ilex glabra - Rhododendron viscosum Swamp Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Atlantic White-cedar / Inkberry - Swamp Azalea Swamp Forest
Colloquial Name: Coastal Plain Atlantic White-cedar Swamp Forest
Hierarchy Level: Association
Type Concept: 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 Chamaecyparis thyoides or codominated with Acer rubrum. Less frequent canopy associates include Pinus rigida, Nyssa sylvatica, and sometimes Tsuga canadensis and Pinus strobus. The shrub layer is very dense and diverse with Clethra alnifolia, Ilex glabra, Morella pensylvanica, Gaylussacia frondosa, Leucothoe racemosa, Rhododendron viscosum, Ilex laevigata, Ilex verticillata, Aronia melanocarpa, and Vaccinium corymbosum. The herbaceous layer tends to be sparse or patchy and limited to sunny openings with Osmunda cinnamomea, Thelypteris palustris, Woodwardia virginica, Woodwardia areolata, Thelypteris simulata, Gaultheria procumbens, Drosera spp., Sarracenia purpurea, Pogonia ophioglossoides, Mitchella repens, Carex striata, Carex collinsii, Carex atlantica, and Toxicodendron radicans. The nonvascular layer includes several species of Sphagnum, commonly Sphagnum fallax, Sphagnum flavicomans, Sphagnum magellanicum, Sphagnum pulchrum, Sphagnum recurvum, and Sphagnum palustre. Key diagnostic characteristics of this association are its coastal setting and the presence of Coastal Plain species such as Ilex glabra, Gaylussacia frondosa, Morella pensylvanica, Leucothoe racemosa, and Clethra alnifolia.

Floristics: This Atlantic white-cedar swamp is dominated by Chamaecyparis thyoides or codominated with Acer rubrum.

The shrub layer is very dense and diverse with Clethra alnifolia, Ilex glabra, Morella pensylvanica (= Myrica pensylvanica), Gaylussacia frondosa (= var. frondosa), Leucothoe racemosa, Rhododendron viscosum, Ilex laevigata, Ilex verticillata, Aronia melanocarpa, and Vaccinium corymbosum. The herbaceous layer tends to be sparse or patchy and limited to sunny openings with Osmunda cinnamomea, Thelypteris palustris, Woodwardia virginica, Woodwardia areolata, Thelypteris simulata, Gaultheria procumbens, Drosera spp., Sarracenia purpurea, Pogonia ophioglossoides, Mitchella repens, Carex striata, Carex collinsii, Carex atlantica, and Toxicodendron radicans.

Dynamics: No Data Available
Environmental Description: Generally occurs in basins overlying sand and gravel deposits or occasionally over glacial lake sediments. Water-saturated peat overlies mineral sediments. Standing water is usually present for at least half the growing season. Water and soil are nutrient-poor, especially low in nitrogen and phosphorus, and high in iron.
Geographic Range: This association occurs on the Atlantic Coastal Plain from Massachusetts to New Jersey.
