Name:
Juncus pelocarpus - Rhynchospora alba - (Nymphaea odorata ssp. odorata) Marsh
Reference:
NatureServe Biotics 2019
Description:
This early-successional community type develops along drawdown edges or in the basins of shallow millponds, beaver ponds, and other impoundments of Inner Coastal Plain stream drainages. It is currently known from four stream drainages associated with Main Creek and the Magothy River in Maryland. This vegetation forms as a result of water levels lowering due to a breach or dam failure. Substrates are extremely acidic (mean pH = 3.8) consisting of mucky peats of variable depths. Stands are typically small-patch with sizes ranging from 0.3 to 1.41 acres. The vegetation is patchy, consisting of species such as <i>Nymphaea odorata ssp. odorata, Dulichium arundinaceum</i>, and <i>Decodon verticillatus</i> in low, mucky pockets. Dense mats of <i>Triadenum virginicum, Juncus pelocarpus, Rhynchospora alba, Eleocharis olivacea var. olivacea, Juncus canadensis</i>, and <i>Carex canescens</i> are commonly interspersed amongst these pockets. Shrubs and small trees of <i>Acer rubrum, Chamaedaphne calyculata, Clethra alnifolia, Vaccinium macrocarpon, Aronia arbutifolia, Alnus serrulata</i>, and <i>Magnolia virginiana </i>may occupy seepage edges, hummocks of tree bases, or be scattered throughout basins at low cover. Additional low-cover associates may include <i>Juncus effusus var. solutus, Utricularia subulata, Rhexia virginica, Carex atlantica, Glyceria obtusa, Xyris jupicai, Sphagnum rubellum</i>, and <i>Sphagnum recurvum</i>.
