Name:
Eriophorum virginicum - Dulichium arundinaceum - Carex echinata Seep Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance accommodates acidic herbaceous fen or "bog" vegetation from the Allegheny Mountains region of Virginia, West Virginia and Maryland as well as related areas of New York and Pennsylvania. Typical components of this community type include <i>Carex echinata, Carex folliculata, Dulichium arundinaceum, Eriophorum virginicum, Juncus brevicaudatus, Juncus canadensis, Juncus subcaudatus</i>, and <i>Solidago uliginosa</i>. Other common herbs include <i>Carex gynandra, Carex trisperma, Doellingeria umbellata, Drosera rotundifolia var. rotundifolia, Epilobium leptophyllum, Galium tinctorium, Juncus effusus, Osmunda cinnamomea, Scirpus cyperinus, Sparganium erectum ssp. stoloniferum</i>, and <i>Viola cucullata</i>. <i>Sphagnum</i> spp. (<i>Sphagnum recurvum, Sphagnum magellanicum, Sphagnum fallax</i>, and others) may also be present. Patches of low shrubs and stunted trees are also present in some examples, particularly <i>Picea rubens</i> and <i>Acer rubrum</i>. Shrubs may include <i>Menziesia pilosa, Kalmia latifolia, Vaccinium angustifolium</i>, and <i>Vaccinium myrtilloides</i>. The dwarf-shrubs <i>Vaccinium oxycoccos, Vaccinium macrocarpon</i>, and <i>Rubus hispidus</i> may be present in some associations. This vegetation is found on flat to gently sloping topography of terraces, toeslopes, shallow headwater basins, swales, moats of bog mats, and pondshores. Some older stands typically occur over shallow bedrock, where they are kept open by high water tables. Some habitats typically have pronounced hummock-and-hollow microtopography. Groundwater discharge may be barely perceptible, or may appear as flowing seeps and braided streamlets. The underlying bedrock may consist of acidic sandstone, shale or limestone. The substrate is poorly to very poorly drained shallow peat or muck or sand.
