cold-deciduous shrubland
III.B.2.N.e.7. VACCINIUM FORMOSUM - VACCINIUM FUSCATUM
SEASONALLY FLOODED SHRUBLAND ALLIANCE
Southern Highbush Blueberry - Black Highbush Blueberry
Seasonally Flooded Shrubland Alliance
Concept: This alliance covers depressional wetlands in uplands
of the Coastal Plain, lower and northern Piedmont, and lower New England
dominated by Vaccinium formosum, Vaccinium fuscatum, and/or Vaccinium corymbosum
as well as other heaths locally, such as Lyonia ligustrina var. foliosiflora,
Lyonia lucida, and others. Other shrub/vine species which may be present include
Leucothoe racemosa, Smilax walteri, and Viburnum nudum var. nudum. In the
northern part of the range, other shrubs include Ilex verticillata, Spiraea
alba, and Clethra alnifolia. The shrub coverage sometimes has an open, sparse
structure. Trees may be interspersed among the shrubs; these may include
Liquidambar styraciflua, Acer rubrum var. rubrum, Pinus palustris, and Pinus
taeda. In the north, Nyssa sylvatica or Pinus rigida may occur. Herbaceous
species that may be present include Carex crinita, Carex glaucescens, Eleocharis sp., Rhynchospora sp., Scleria sp., and Utricularia gibba. Sphagnum spp. are
present in some examples. Vaccinium spp. sometimes exceed 5 m in height, but are
placed here.
Range: This alliance is found in uplands of the Coastal Plain,
lower and northern Piedmont, and lower New England, south to the Carolinas.

Upland Depression Shrub Ponds (340-50; 1.6.4.1)
Concept:
Depressional wetlands in uplands, dominated by Vaccinium formosum, Vaccinium
fuscatum, and (locally) other heaths, such as Lyonia ligustrina var.
foliosiflora, Lyonia lucida, and others. These ponds are smaller,
steeper-sided, and flooded for shorter duration than herbaceous-dominated ponds.
