Average Soil Texture: sandy loam soil, pH 3.8, with 2” layer of organic matter on surface, overlying sand of the Cohansey Formation.
Landscape Description: 1.5-acre, pondshore community in good condition within a 2.5-acre, diverse coastal plain intermittent pond surrounded by Atlantic white cedar and mixed deciduous-evergreen lowland forest. Site is located on the Richard Stockton College campus surrounded by mixed deciduous-evergreen lowland forest. A large sand mine (1500x300') stretches S to NE of the site. The Garden State Parkway lies to the E of that. The site is in the SE corner of a wetland that forms the headwaters of one branch of Morses Mill Stream.

Community Type: coastal plain pond
General Description: Coastal plain intermittent pond within mixed evergreen-deciduous lowland forest, about 400 feet south of a wetland drained by a manmade channel flowing north into Morses Mill Stream. The area is relatively flat, underlain by sand of the Cohansey Formation. Rhexia virginica - Panicum verrucosum Herbaceous Vegetation dominates two patches (A1, A2) in the southern upper zone of the pond. It is surrounded by a Carex striata var. brevis-dominated zone (A3), with Sphagnum cuspidatum and Drosera intermedia. Two sparsely vegetated central patches (A4) are dominated by Carex sp., with Eriocaulon aquaticum, Panicum verrucosum, Xyris smalliana, Scleria reticularis, Dichanthelium sp., Eleocharis olivacea, Drosera intermedia and Proserpinaca pectinata. There are patches of Cladium mariscoides throughout the Carex zone and Chamaedaphne calyculata in the upper zone. The pond is surrounded by a 30-40 feet wide band (A5) dominated by Chamaecyparis thyoides and Vaccinium corymbosum, with Sphagnum cuspidatum, Gaylussacia dumosa, Smilax glauca and Acer rubrum. This is surrounded by mixed evergreen-deciduous lowland forest. The pond is located in forested wetlands on the campus of Richard Stockton College, about 800 feet west of the Garden State Parkway. The suburbs of the town of Pomona are about 3000 feet to the south. There appears to be no current anthropogenic disturbance to the pond, though its hydrology may have been affected by sand excavation in a large (2000 x 80 feet) pit that lies 200 feet east of the site, as well as regional drawdown of the water table.
Community Description: Good quality herbaceous pondshore community in central to upper zones of a coastal plain intermittent pond. Community spans most of the pond, covering about three-quarters of the herbaceous area. Relatively homogeneous mix of species dominated by Carex striata var. brevis (65%), with Sphagnum cuspidatum (20%, greater abundance in some areas), Drosera intermedia (1%, more prevalent in depressions recently filled with water) and patches of Cladium mariscoides and Chamaedaphne calyculata (only along the upper shore). About 15% unvegetated surface (10% litter and duff, 5% bare soil). Sandy loam soil, pH 3.8, with 2” layer of organic matter on surface, overlying sand of the Cohansey Formation. Fully exposed area with very gentle slope (0-3%).
Community Description (field): Herbaceous zone found throughout most of the coastal plain pond. Where Carex striata var. brevis is thinner, Sphagnum becomes more prevalent. Where depressions accumulate more water, Drosera and open soil are more prevalent. Cladium and Chamaedaphne are found in patches, with the Chamaedaphne resticted to the outer edge of the costal plain pond.
Additional species found but not present in the plot: Chamaedaphne calyculata (in patches) (0.01%), Cladium mariscoides (diffuse in some areas) (0.01%)
NOTE: Although the whole pond, 2.5 acres, was mapped for this occurrence, Carex striata var. brevis Herbaceous Vegetation occupies approximately 1.5 acres of the pond.
