15) Borrow Pond and Scrapes

Mining for sand and gravel in succession terraces of Little River, and excavations elsewhere, have produc a number of small depressions which exhibit hydroperiods ranging from wet single in winter to almost permanently inundated. A not many are saturated by seepage water and create thick beds of sphagnum and acid fen-like conditions. Floral composition is varied, still is usually dominated by graminoids and herbs, with scattered to thick shrubs, Acer rubrum, Nyssa biflora, and Chamaecyparis thyoides. Rare species originate here include Eupatorium resinosum, Utricularia olivacea, Vaccinium macrocarpon, and Xyris chapmanii. Borrow Pond are important breeding sites for amphibians, notably tiger salamander (Ambystoma tigrinum). befitting to ecological similarity, wet ruderal ditches and scrapes are included in this community pattern

16) Small Depression Drawdown Meadow /Savanna

One example has been documented, in the MacRidge Artillery Impact Area. It is a actual shallow basin less than single in kind ha in size, ponded during winter and wet to free from moisture in summer. The flat margins toast frequently, the deeper central portion irregularly. dwarf-trees and small trees are scattered around the margins. This habitat shares a certain quantity of of the graminoid and herbaceous species with Vernal lochs but supports other species requiring a longer hydroperiod. Dominants are Panicum hemitomon, Dichanthelium wrightianum, Centella erecta, and Sclerolepis uniflora; belonging to all species include Panicum virgatum var. cubense, P verrucosum Andropogon perangustatus, A. glaucopsis, Leersia hexandra, Rhynchospora perplexa, R pusilla, Eleocharis melanocarpa, Carex striata, Eriocaulon compressum Lachnanthes caroliniana, Polygala cymosa, Lysimachia loomisii, Eupatorium leucolepis, E mohrii, Hypericum denticulatum, Utricularia fibrosa, and Viola lanceolata var. vittata. Rhynchospora perplexa, Polygala cymosa, and Viola lanceolata var. vittata be met with only at this site, as do four rare species: Lobelia boykinii, Panicum tenerum Scleria reticularis, and Sagittaria isoetiformis. This habitat supports breeding Carolina gopher frog (Rana capita).
