Community Type: coastal plain pond
General Description: Coastal plain intermittent pond in pitch pine-scrub oak- heath forest, likely remaining inundated except in severe drought years. The surrounding landscape is undulating with intermittent ponds scattered every few hundred feet around the southeastern drainages of the Pope Branch, an upper tributary of the Wading River and associated Atlantic white cedar swamps. Underlying soil is sand of the Cohansey Formation. Rhexia virginica - Panicum verrucosum Herbaceous Vegetation dominates the upper western zone of the pond. The central zone of the pond is dominated by Juncus pelocarpus and Eleocharis robbinsii, with Nymphoides cordata, Eleocharis olivacea, Drosera intermedia, Rhynchospora alba, Eriocaulon aquaticum, Panicum verrucosum, Smilax rotundifolia and Sphagnum sp. On the east, north and south, the adjacent pondshore is dominated by Vaccinium corymbosum with a narrow, intermittent band of Chamaedaphne calyculata and scattered Decodon verticillatus and Acer rubrum, along with Leucothoe racemosa, Clethra alnifolia, Ilex glabra, Photinia pyrifolia and Sphagnum sp. The pond is surrounded by a large expanse of Pinus rigida dominated forest to the east and south, with Chamaecyparis thyoides swamp to the north, along the Pope Branch. A large cranberry bog replaces the cedar swamp to the north about 3000’ and a Superfund site is fenced off and monitored about 3000’ to the northeast. A paved road lies about 5000’ to the northeast and 8000’ north. Sand roads traverse the surrounding forest. Part of pond had been crisscrossed by dirt bikes, but the surrounding area is generally undisturbed, except for hunting or for forest management (logging or fire management).
Community Description: Excellent quality herbaceous pondshore community occurring in the narrow upper shore of a coastal plain intermittent pond. Community occurrence is sparsely vegetated, dominated by Panicum verrucosum (25%), with Sphagnum sp. (5-15%), less than 1% Amphicarpum purshii, Triadenum virginicum, Rhynchospora alba, Cladium mariscoides, Carex striata var. brevis, Andropogon gyrans, Juncus pelocarpus and Rhexia sp., and 70% unvegetated surface cover (60% bare soil, 10% litter and duff). Soil is sand of the Cohansey Formation. No standing water on survey date. Full sun exposure, gentle slope (0-3º).
Community Description (field): Herbaceous zone along W edge of coastal plain pond, dominated by Panicum verrucosum, with a patch of Cladium.
NOTE: Ground water quality is monitored at Superfund site ½ mile to the north and toxins from that site could be affecting this area. Although the whole 6.4-acre pond was mapped for this occurrence, Rhexia virginica - Panicum verrucosum Herbaceous Vegetation occupies approximately 0.6 acres of the pond.
