CEGL006260 Trichophorum cespitosum - Gaylussacia dumosa / Sphagnum (fuscum, rubellum, magellanicum) Acidic Peatland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Tufted Bulrush - Dwarf Huckleberry / (Brown Peatmoss, Red Peatmoss, Magellan''s Peatmoss) Acidic Peatland
Colloquial Name: Maritime Peatland Sedge Lawn
Hierarchy Level: Association
Type Concept: This is the sedge-dominated, ombrotrophic, coastal bog community of northern New England and adjacent Canadian maritime provinces. It occurs on the central, raised, relatively drier portions of maritime peatlands. The substrate is Sphagnum peat, usually saturated, and is acidic, around pH 4.5. Trees and shrubs are absent to sparse; dwarf-shrub cover is variable, from sparse to (rarely) over 80%. Even where dwarf-shrubs are abundant, however, their short stature allows the sedge lawns to visually dominate the vegetation. The bryoid layer is continuous. The peatland "lawns" are characterized by abundant Trichophorum cespitosum. Scattered low shrubs include Gaylussacia dumosa and Chamaedaphne calyculata, as well as occasional Kalmia angustifolia, Kalmia polifolia, Vaccinium oxycoccos, Andromeda polifolia var. glaucophylla, Ledum groenlandicum, Rubus chamaemorus, and Empetrum nigrum. Other associates include Eriophorum vaginatum var. spissum, Arethusa bulbosa, Calopogon tuberosus, Drosera rotundifolia, and Solidago uliginosa. The bryophyte layer is dominated by Sphagnum rubellum and Sphagnum fuscum, as well as Sphagnum magellanicum and Sphagnum flavicomans. Fruticose lichens characterize and distinguish this association and include Cladonia rangiferina, Cladonia arbuscula ssp. mitis, Cladonia arbuscula, Cladonia terrae-novae, Cladonia uncialis, and Cladonia crispata. Diagnostic characters for this association are its location in maritime peatlands and the relative abundance of Trichophorum cespitosum with other peatland plants. Empetrum nigrum and Rubus chamaemorus are also good indicators.
