Name:
Vaccinium macrocarpon Coastal Wet Shrubland Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance is made up of interdunal swales, as well as and peaty basin wetlands underlain by morainal deposits, from New England south to Delaware. The dwarf-shrub <i>Vaccinium macrocarpon</i> forms a low thicket, sometimes overtopped and obscured by other shrubs and tall herbs. Scattered <i>Morella pensylvanica, Vaccinium corymbosum, Clethra alnifolia</i>, and other shrubs may be prominent. <i>Morella pensylvanica</i>, although a minor component of the vegetation and generally restricted to the wetland edge, characterizes this community as coastal. Associated species commonly include <i>Cladium mariscoides, Xyris torta, Xyris difformis, Rhynchospora capitellata, Rhynchospora alba, Cyperus</i> spp., <i>Drosera rotundifolia, Drosera intermedia, Drosera filiformis, Woodwardia virginica, Onoclea sensibilis, Pogonia ophioglossoides</i>, and scattered clumps of <i>Schoenoplectus pungens</i> or <i>Scirpus cyperinus</i> in small wet pockets. <i>Sphagnum</i> spp. (<i>Sphagnum rubellum, Sphagnum compactum</i>, and possibly others) cover the substrate. This alliance occurs most frequently in a maritime interdunal swale setting, seasonally flooded by groundwater and rainwater. It also occurs less commonly in saturated peaty basins of moraines, usually on coastal islands where <i>Chamaedaphne calyculata</i> is absent.
