Name:
Carex atlantica - Solidago patula - Parnassia asarifolia Seep Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance accommodates shrub- and herb-dominated vegetation of Southern Appalachian "bogs," seeps or poor fens, found at a variety of elevations. Physiognomy is variable and may include herbaceous-dominated patches, shrubby areas, and areas with an open canopy of trees. There may be a mosaic or zoned pattern of shrub thickets and herb-dominated areas, much of it underlain by <i>Sphagnum</i> mats. The shrub stratum is open to dense, and is dominated by <i>Alnus serrulata, Kalmia latifolia, Lindera benzoin var. benzoin, Lyonia ligustrina, Rhododendron maximum</i>, and <i>Vaccinium fuscatum</i>. Typical herbaceous species include <i>Carex atlantica, Carex folliculata, Carex gynandra, Carex leptalea, Impatiens capensis, Juncus gymnocarpus, Mimulus ringens, Osmunda cinnamomea, Oxypolis rigidior, Rhynchospora capitellata, Rudbeckia laciniata var. laciniata, Scirpus georgianus, Scutellaria lateriflora, Solidago patula var. patula</i>, and <i>Thelypteris noveboracensis</i>. <i>Sphagnum</i> species include <i>Sphagnum affine, Sphagnum bartlettianum, Sphagnum palustre</i>, and <i>Sphagnum recurvum</i>. If a tree canopy is present, it will be open and contain species such as <i>Acer rubrum var. trilobum, Betula lenta, Magnolia tripetala</i>, and <i>Nyssa sylvatica</i>. Examples can be physiognomically mixed or variable, with shrubby examples interspersed with small to moderately large herbaceous openings. Examples may occur in stream headwaters and on the edges of small stream floodplains where groundwater seepage emerges and provides a relatively constant flow and saturated conditions. Examples also occur on slight to fairly steep slopes (1-15%) on shallow soils over bedrock.
