Alnus serrulata / Sanguisorba canadensis / Parnassia grandifolia - Helenium brevifolium Shrubland
Reference:
Southeastern Ecology Working Gro...
Description:
This association is apparently restricted to western Virginia in Grayson and Carroll counties, and in adjacent Allegheny County, North Carolina (degraded example of uncertain placement). A similar type of vegetation occurs on Bluff Mountain in North Carolina. All known occurrences are in seepage areas underlain by hornblende, gabbro, or gneiss at elevations ranging from about 700-1100 m (2400-3500 feet). This community has a mixed physiognomy ranging from shrub thicket to herbaceous. In general it occurs as a shrubland of Alnus serrulata, Spiraea alba var. latifolia (= Spiraea latifolia), Spiraea tomentosa, and Lyonia ligustrina var. ligustrina. Typically there are a few scattered individuals of Pinus strobus and Acer rubrum but tree cover rarely reaches 10%. The herbaceous layer is relatively continuous and may be quite diverse. Herbaceous species include Glyceria striata, Juncus subcaudatus, Osmunda regalis, Oxypolis rigidior, Viola cucullata, Eleocharis tenuis, Cirsium muticum, Dichanthelium dichotomum, Houstonia caerulea, Oenothera perennis, Sanguisorba canadensis, Parnassia grandifolia, Symphyotrichum novi-belgii (= Aster novi-belgii), Carex atlantica, Helenium brevifolium, Solidago uliginosa, Calopogon tuberosus, Muhlenbergia glomerata, Schizachyrium scoparium, Xyris torta, Panicum virgatum, Rhynchospora capitellata, Rhynchospora alba, and Selaginella apoda.
