Name:
Pinus strobus - Acer rubrum Saturated Woodland Alliance
Reference:
Southeastern Ecology Working Gro...
Description:
This alliance contains woodlands associated with seepage areas of mineral soil derived from mafic bedrock. Canopies are composed of mixtures of deciduous and evergreen species including Pinus strobus, Acer rubrum, Pinus rigida, and Quercus rubra. Shrub layers are variable in density and composition, but typical species include Physocarpus opulifolius, Rhamnus alnifolia, Lyonia ligustrina, and Alnus serrulata. The herbaceous stratum of associations in this alliance contains species indicative of mafic conditions, such as Parnassia grandifolia, Sanguisorba canadensis, Viola walteri, and Helenium brevifolium. Other herbaceous species known from associations in this alliance include Aconitum uncinatum, Symphyotrichum novi-belgii (= Aster novi-belgii), Carex atlantica, Castilleja coccinea, Cirsium muticum, Dichanthelium clandestinum, Dichanthelium dichotomum, Eleocharis tenuis, Glyceria striata, Houstonia caerulea, Juncus subcaudatus, Oenothera perennis, Osmunda cinnamomea, Osmunda regalis var. spectabilis, Oxypolis rigidior, Pycnanthemum tenuifolium, Rhynchospora alba, Rubus hispidus, Scirpus expansus, Solidago uliginosa, Thalictrum pubescens, and Viola cucullata. This alliance currently contains mafic wetlands in the southern Blue Ridge of Virginia. Other Pinus strobus saturated woodlands may occur in southern New England, but these are not well known and are not restricted to mafic bedrock formations.
