Description:
This community includes non-alluvial wetland vegetation influenced by circumneutral seepage, in the southern Appalachian Mountains. It 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. Examples are herb-dominated but may contain scattered shrubs, or be locally dominated by the dwarf-shrub <i>Vaccinium macrocarpon</i>. <i>Sphagnum</i> cover is greater than 50%. Dominant herbaceous species include <i>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, Parnassia asarifolia</i>, and <i>Houstonia serpyllifolia</i>. Bryophytes that may be present are <i>Sphagnum palustre, Sphagnum affine, Sphagnum bartlettianum, Sphagnum recurvum, Aulacomnium palustre</i> and northern disjuncts such as <i>Sphagnum warnstorfii, Sphagnum fuscum, Sphagnum subsecundum, Sphagnum angustifolium, Sphagnum subtile</i>, and <i>Sphagnum flexuosum var. flexuosum</i>.
