CEGL004994 Pinus strobus - Acer rubrum / Spiraea alba var. latifolia / Sanguisorba canadensis Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Eastern White Pine - Red Maple / Broadleaf Meadowsweet / Canadian Burnet Woodland
Colloquial Name: Southern Blue Ridge Mafic Woodland Seep
Hierarchy Level: Association
Type Concept: This mixed woodland occupies mafic seepage wetlands of the Southern Blue Ridge plateau in Virginia and possibly North Carolina. Dominant trees are Acer rubrum, Pinus strobus, and less frequently Pinus rigida in open (25-60% canopy cover) stands. The subcanopy of well-developed or mature stands is primarily Acer rubrum. Shrub layers are moderately dense to dense (40-80% cover); characteristic shrubs include Spiraea alba var. latifolia, Alnus serrulata, Kalmia latifolia, Vaccinium corymbosum, Physocarpus opulifolius, Rhododendron viscosum, Lyonia ligustrina, and Spiraea tomentosa. Herbaceous cover is variable and includes a number of species indicative if mafic conditions, particularly Sanguisorba canadensis, Viola walteri, Helenium brevifolium, and a narrow-leaved, apparently undescribed, Aster taxon related to Symphyotrichum puniceum. Other typical herbs include Osmunda regalis var. spectabilis, Osmunda cinnamomea, Solidago uliginosa, Oxypolis rigidior, Thalictrum pubescens, Pycnanthemum tenuifolium, Viola cucullata, Rubus hispidus, and Scirpus expansus.

Floristics: This community generally occurs as a woodland having a somewhat stunted, open (25-60% cover) canopy of Pinus strobus and Acer rubrum. Pinus rigida is an occasional canopy associate, probably indicative of past fires. A subcanopy tree layer is often absent or, where present, dominated by Acer rubrum. Shrub layers are moderately dense to dense (40-80% cover); characteristic shrubs include Spiraea alba var. latifolia, Alnus serrulata, Kalmia latifolia, Vaccinium corymbosum, Physocarpus opulifolius, Rhododendron viscosum, Lyonia ligustrina, Rhamnus alnifolia, and Spiraea tomentosa. The herbaceous layer includes Glyceria striata, Juncus subcaudatus, Osmunda regalis var. spectabilis, Osmunda cinnamomea, Solidago uliginosa, Oxypolis rigidior, Thalictrum pubescens, Pycnanthemum tenuifolium, Rubus hispidus, Viola cucullata, Eleocharis tenuis, Cirsium muticum, Dichanthelium dichotomum, Houstonia caerulea, Oenothera perennis, Parnassia grandifolia, Symphyotrichum novi-belgii (= Aster novi-belgii), Carex atlantica, Aconitum uncinatum, Castilleja coccinea, Rhynchospora alba, Scirpus expansus, and Dichanthelium clandestinum. Herb cover may be dense in small openings, but only moderate in shaded microhabitats. Species indicative of mafic conditions include Sanguisorba canadensis, Viola walteri, Helenium brevifolium, Parnassia grandifolia, and a narrow-leaved, apparently undescribed Aster taxon related to Symphyotrichum puniceum (= Aster puniceus).
Dynamics: No Data Available
Environmental Description: This community occurs in seepage areas on mineral soil weathered from amphibolite and ultramafic rocks of the Southern Blue Ridge. Occurrences are generally linear, following braided, rocky drainages with internal hummocks of organic-rich soil.
Geographic Range: This community is known from the southern Blue Ridge Mountains of Virginia; it may also occur in North Carolina, Pennsylvania, and Maryland.
