Type Concept: This seasonally flooded wetland occurs on the North Atlantic Coastal Plain in topographically defined basins of New Jersey and possibly Long Island, New York. This type of pond tends to be a bit weedy and is probably indicative of disturbance; however, the overall diversity and number of native Polygonum species is remarkable. The dominant species are Polygonum hydropiper, Polygonum punctatum, Polygonum lapathifolium, Bidens connata, Bidens frondosa, and Leersia oryzoides. Other associates include Bidens discoidea, Bidens tripartita, Bidens vulgata, Carex albolutescens, Cyperus erythrorhizos, Cyperus esculentus, Cyperus odoratus, Cyperus retrorsus, Cyperus strigosus, Decodon verticillatus, Dichanthelium dichotomum var. ensifolium, Digitaria filiformis, Dulichium arundinaceum, Echinochloa crus-galli, Echinochloa muricata, Echinochloa walteri, Eleocharis olivacea, Eleocharis ovata, Erechtites hieraciifolius, Eupatorium perfoliatum, Euthamia graminifolia, Fimbristylis autumnalis, Glyceria obtusa, Hypericum mutilum, Juncus bufonius, Juncus canadensis, Lindernia dubia var. anagallidea, Ludwigia palustris, Ludwigia sphaerocarpa, Lycopus amplectens, Lycopus uniflorus, Nuphar advena, Osmunda cinnamomea, Panicum dichotomiflorum, Panicum rigidulum var. pubescens, Panicum verrucosum, Polygonum arifolium, Polygonum careyi, Polygonum cespitosum, Polygonum densiflorum, Polygonum hydropiperoides, Polygonum pensylvanicum, Polygonum persicaria, Polygonum sagittatum, Proserpinaca palustris, Proserpinaca pectinata, Rhynchospora macrostachya, Rhynchospora scirpoides, Rubus hispidus, Rubus pensilvanicus, Rumex acetosella, Scirpus cyperinus, Solanum physalifolium, Solidago rugosa, Sphagnum cuspidatum, Sphagnum fimbriatum, Spiraea tomentosa, Symphyotrichum pilosum var. pilosum, Toxicodendron radicans, Triadenum virginicum, Viola x primulifolia, and Viola lanceolata. This vegetation occurs throughout flat basins, particularly in the center where standing water is above or close to the soil surface most of the growing season. The substrate is muck over sand.
