Description:
This community includes non-alluvial wetland vegetation influenced by circumneutral seepage, in the southern Appalachian Mountains. Examples are herb dominated, but may contain scattered shrubs, or be locally dominated by the dwarf-shrub Vaccinium macrocarpon. Sphagnum cover is greater than 50%. Dominant herbaceous species include Eriophorum virginicum, Carex atlantica, Carex echinata, Rhynchospora alba, Rhynchospora capitellata, Schizachyrium scoparium, Scirpus expansus, Scirpus cyperinus, Scirpus polyphyllus, Scirpus atrovirens, Oxypolis rigidior, Solidago patula var. patula, Packera aurea (= Senecio aureus), Parnassia asarifolia, and Houstonia serpyllifolia. Bryophytes that may be present are Sphagnum palustre, Sphagnum affine (= Sphagnum imbricatum), Sphagnum bartlettianum, Sphagnum recurvum, Aulacomnium palustre and northern disjuncts such as Sphagnum warnstorfii, Sphagnum fuscum, Sphagnum subsecundum, Sphagnum angustifolium, Sphagnum subtile, and Sphagnum flexuosum var. flexuosum. This community occurs over amphibolite (a mafic metamorphic rock), at 1200-1450 m (4000-4700 feet) elevation, on slight to fairly steep slopes (1-15%), is slightly to strongly seepage-fed, and generally has shallow, gravelly, soils. It is known only from the valley of Long Hope Creek, Ashe and Watauga counties, North Carolina, where 15-20 examples occur.
