| Landscape Narrative |
Soil Description: Soil is 1” layer of muck, pH 3.8, overlying sand and clay of the Lower Member.
Water Table: Depth to water table is about 5” below the surface, with the exception of inundated areas which have standing water3-5” above the soil surface.
Landscape Description: Medium-size, 0.8-acre pondshore community in good condition (however, may be a former cranberry bog) within a 2.2-acre coastal plain pond surrounded by mixed deciduous-evergreen wetland forest which is in close proximity to two other ponds. Site is on a coastal peninsula, about 3000’ west of the ocean in close proximity (0.1 mile) to the limit of tidal waters. Underlying soil substrate is sand and clay of the Lower Member. Carex striata var. brevis Herbaceous Vegetation dominates the middle zone (A2) of the pond, surrounding the central zone (A1) of water with submerged Sphagnum palustre and patches of Decodon verticillatus with Triadenum virginicum. The upper shrub zone (A3) is dominated by Chamaedaphne calyculata and Sphagnum fallax, with Vaccinium macrocarpon, Woodwardia virginica, Carex striata var. brevis, Decodon verticillatus, Clethra alnifolia, Vaccinium corymbosum, Acer rubrum and Chamaecyparis thyoides. The surrounding wetland forest (A4) is dominated by Chamaecyparis thyoides, with Vaccinium corymbosum, Acer rubrum, Clethra alnifolia, Rhododendron viscosum, Leucothoe racemosa and Nyssa sylvatica. Wetland forest surrounds the pond, providing a buffer of about 2000’ west, south and east, with residential areas, marinas, salt marshes and recreational areas beyond the forest. A mix of forest and tidal marsh extends north about 6000’ before reaching the sea. The pond may have been a cranberry bog. ORV trails traverse the surrounding forest. Drainage channels cut through parts of the surrounding buffer land.
ORVs go through some of the area. This is part of an ~1000 x 2000' tract of forest surrounded by residential areas and the bay coast. Some of the surrounding area is part of the Natural Lands Trust.

Community Type: coastal plain pond
Community Description: Good quality herbaceous pondshore community occurring in the middle zone of a coastal plain intermittent pond. Dominant species include Carex striata var. brevis (35%) and Sphagnum spp. (S. fallax and S. palustre) (50%), with Decodon verticillatus (10%), Triadenum virginicum (5%), Drosera intermedia (1%) and less than 1% Lachnanthes caroliniana. Carex striata var. brevis, Decodon verticillatus and Triadenum virginicum growing on hummocks throughout. Variable aspect, very gentle slope.
Community Description (field): Herbaceous zone dominated by Carex striata var. brevis, surrounding the central coastal plain pond. Decodon verticillatus may be co-dominant but is difficult to see at this time amongst the Carex. This area is 3-5" higher in elevation than adjacent inundated areas. There are small patches of standing water, but most of the ground is exposed with a mat of Sphagnum glistening with moisture. Carex and Decodon grow on hummocks throughout, with Triadenum.
Note: Although the whole 2.2-acre pond was mapped for this occurrence, Carex striata var. brevis Herbaceous Vegetation occupies approximately 0.8 acres of the pond.
