CEGL006008 Chamaedaphne calyculata - (Gaylussacia dumosa) - Decodon verticillatus / Woodwardia virginica Acidic Peatland

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Leatherleaf - (Dwarf Huckleberry) - Swamp-loosestrife / Virginia Chainfern Acidic Peatland

Colloquial Name: Southern New England Poor Fen

Hierarchy Level:  Association

Type Concept: This dwarf-shrub quaking or floating bog occurs in the southern portion of the glaciated Northeast, extending west to the Western Allegheny Plateau. It occupies oligotrophic, peat-accumulating basins. Chamaedaphne calyculata is strongly dominant, with associate species including Kalmia angustifolia, Kalmia polifolia, Vaccinium oxycoccos, Vaccinium macrocarpon, Gaylussacia dumosa (on the coast), and Gaylussacia baccata. Associate shrubs generally occur with low cover, although they may be locally common. Scattered tall shrubs, such as Vaccinium corymbosum, Rhododendron viscosum, 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, Eriophorum virginicum, Drosera rotundifolia, Drosera intermedia, Sarracenia purpurea, and Woodwardia virginica scattered throughout and with Carex canescens, Carex limosa, Glyceria canadensis, 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.

Floristics: Chamaedaphne calyculata is strongly dominant, with associate species including Kalmia angustifolia, Kalmia polifolia, Vaccinium oxycoccos, Vaccinium macrocarpon, Gaylussacia dumosa (near the coast), and Gaylussacia baccata. Associate shrubs generally occur with low cover, although they may be locally common. Scattered tall shrubs, such as Vaccinium corymbosum, Rhododendron viscosum, Lyonia ligustrina, 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, Decodon verticillatus, Drosera rotundifolia, Drosera intermedia, Sarracenia purpurea, and Woodwardia virginica scattered throughout and with Carex canescens, Carex limosa, Carex folliculata, Carex atlantica, Glyceria canadensis, 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.
