Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Red Peatmoss - Small Cranberry Fen

Colloquial Name: Oligotrophic Peatland Moss Lawn

Hierarchy Level:  Association

Type Concept: This open sphagnum moss lawn occurs within floating or grounded peat mats in very acidic portions of open peatlands (pH <4) isolated from upland runoff or lake water. It is found in the northeastern U.S. from Maine to Pennsylvania. Sphagnum rubellum is strongly dominant. Vaccinium oxycoccos is prominent, despite its diminutive stature. Stunted Chamaedaphne calyculata is always present with variable cover. Additional dwarf-shrubs can include Vaccinium macrocarpon, Kalmia polifolia, Kalmia angustifolia, Andromeda polifolia var. glaucophylla, and occasionally Gaylussacia dumosa near the coast. Herbaceous species often include Sarracenia purpurea, Rhynchospora alba, Eriophorum virginicum, Drosera rotundifolia, Drosera intermedia, Xyris montana, Juncus pelocarpus, Utricularia cornuta, and occasionally Eriophorum vaginatum var. spissum.
