| Landscape Narrative |
Soil Description: sandy loam, pH 4.0, overlying sand of the Cohansey Formation
Landscape Description: 0.7-acre pondshore community in good condition within a 1.7-acre coastal plain intermittent pond surrounded by pitch pine woodland. Coastal plain intermittent pond about 150 feet north of White Marsh Run, within forested wetlands that extend west and east along the river. The surrounding forest north and south of the site is more upland, with mixed deciduous evergreen forest growing on the sands of the Cohansey Formation. Rhexia virginica - Panicum verrucosum Herbaceous Vegetation dominates the central to middle zones of the pond (A1). The adjacent upper pondshore zone (A2) is dominated by Decodon verticillatus, with Panicum verrucosum, Cephalanthus occidentalis, Glyceria obtusa, Dulichium arundinaceum, Carex sp., Triadenum virginicum, Hypericum canadense, Rhynchospora fusca, Conyza canadensis, Juncus canadensis, Cuscuta sp. and Rhexia sp. The surrounding forested zone (A3) is dominated by Acer rubrum and Vaccinium corymbosum, with Clethra alnifolia, Nyssa sylvatica, Pinus rigida, Smilax rotundifolia, Rhododendron viscosum, Sphagnum sp., Panicum verrucosum, Magnolia virginica and Woodwardia virginica. Fire scars can be seen on the pine trunks with 8-24" diameter. Forested wetlands surround the site to the east and west, with mixed coniferous deciduous forest in surrounding uplands, as well as agricultural fields and residential zones. Fairton Rd. is 500' to the north. Site is in Buckshutem Wildlife Management Area and there is little anthropogenic disturbance in the surrounding buffer area other than runoff from agricultural fields and pollution associated with proximity to residential areas.

Community Type: coastal plain pond
Community Description: Herbaceous pondshore community occurring in the central to middle zones of a coastal plain intermittent pond. Dominant species is Panicum verrucosum (80%), with a large patch (8 x 8 feet) of Panicum rigidulum var. pubescens (covering about 60% with 40% bare soil) in the center of the pond, and less than 1% Hypericum canadense, Triadenum virginicum, Gnaphalium obtusifolium and seedlings of Acer rubrum and Cephalanthus occidentalis. Bare soil makes up 10% and litter and duff make up 10% of the 20% unvegetated surface cover in the Panicum-dominated area. Full sun exposure with very small slope (0-3ยบ).
Note: Although the whole 1.7-acre pond was mapped for this occurrence, Rhexia virginica - Panicum verrucosum Herbaceous Vegetation occupies approximately 0.7 acres of the pond.
