| Landscape Narrative |
Soil Description: sandy loam soil, pH 3.8, overlies sand of the Cohansey Formation
Landscape Description: 1.1-acre pondshore community in good condition within a large, 4.5-acre, coastal plain intermittent pond surrounded by high quality pine-oak-heath forest which surrounds for 1 mile or more in all directions. Site is just northeast of the headwaters of the Slab Branch which flows west and south into the Maurice River. The surrounding landscape is relatively flat, underlain by sand substrate of the Cohansey Formation. Slab Branch flows west, joining Middle and Nixons Branches to flow into Muskee Creek about a mile west of the site. Carex striata var. brevis Herbaceous Vegetation dominates the central zone of the pond (A1). The adjacent middle to outer zone of the pond (A2) is dominated by Panicum virgatum, with Saccharum giganteum, Carex striata var. brevis, Sphagnum sp., and Panicum sp. The pond is surrounded by a dense thicket of shrubs (A3) growing on hummocks dominated by Acer rubrum, Clethra alnifolia and Leucothoe racemosa, with Smilax rotundifolia, Sphagnum tenerum, Vaccinium corymbosum, Nyssa sylvatica, Liquidambar styraciflua, Pinus rigida, Solidago sp. and Woodwardia virginica. Mixed deciduous evergreen forest extends around the site, with some Atlantic white cedar along the rivers. The site is in Peaslee Wildlife Management Area, about 1200 feet southwest of a powerline right-of-way, within a network of sand roads, but otherwise undisturbed surrounding buffer. Other intermittent ponds documented by the Pinelands Commission lie about 2000' east and southeast.

Community Type: coastal plain pond
Community Description: Good quality herbaceous pondshore community occurring in the central zone of a coastal plain intermittent pond. Dominant species is Carex striata var. brevis (30%), with Liquidambar styraciflua (25%), saplings of Acer rubrum (9%), Sphagnum palustre (25%), Cladium mariscoides (3%) and Panicum sp. (0.5%). Distribution is fairly homogeneous, with one central patch of pure Sphagnum, and a few bare patches. Variable aspect, very little slope (0-3º).
Community Description (field): This is the central zone of a coastal plain pond with a mature Acer rubrum and Liquidambar styraciflua canopy and a Carex striata var. brevis groundcover with Sphagnum. There is one small patch of pure Sphagnum near the center of the trees and a few patches of bare ground. Acer rubrum have 6-12" diameters. The groundcover is evenly spread throughout except in the patches of Sphagnum and bare ground.
Note: Although the whole 4.5-acre pond was mapped for this occurrence, Panicum virgatum Herbaceous Vegetation occupies approximately 1.1 acres of the pond.
