Vaccinium macrocarpon - Morella pensylvanica Dwarf-shrubland
Reference:
Eastern Ecology Working Group of...
Description:
This association is a small-patch seasonally flooded wetland within low swales behind backdunes of major dune systems of the northeastern coast. Vegetation is characterized by Vaccinium macrocarpon, Sphagnum spp., and scattered Morella pensylvanica (= Myrica pensylvanica), Myrica gale, and/or Vaccinium corymbosum. Vaccinium macrocarpon is generally dominant, but a number of rushes, sedges, grasses, and forbs co-occur and often obscure the low-growing Vaccinium macrocarpon. Morella pensylvanica, although a minor component of the vegetation and generally restricted to the wetland edge, characterizes this community as coastal. The wetland is seasonally flooded and is often dry on the surface late in the growing season. A shallow layer of peat overtops deep sand deposits. Associated species commonly include Juncus spp. (Juncus canadensis, Juncus greenei, Juncus balticus, Juncus biflorus, Juncus scirpoides, Juncus pelocarpus and/or others), Cladium mariscoides, Xyris torta, Xyris difformis, Rhynchospora capitellata, Rhynchospora alba, Cyperus spp., Drosera rotundifolia, Drosera intermedia, Drosera filiformis, Pogonia ophioglossoides, and scattered clumps of Schoenoplectus pungens or Scirpus cyperinus in small wet pockets. Sphagnum spp. (Sphagnum rubellum, Sphagnum compactum, and possibly others) cover the surface. Species occurring less frequently can include Linum striatum, Lycopodiella inundata (= Lycopodium inundatum), Polygala cruciata, Calopogon spp., Platanthera spp., Utricularia subulata, Triadenum sp., and others. Floristics can vary among swales due to hydrology, soils, or disturbance regime.
