Observation Narrative ? Community Type: coastal plain pond Community Description: Lowest area of coastal plain pond dominated by Lindernia dubia and moss. Several other species are scattered throughout, creating a relatively homogenous patch, with a relatively large percentage of bare soil. Soil remains moist, but there is no standing water. Just to the S of this patch is a patch of nearly pure Eleocharis ovata. Only scattered Polygonum interupts the monoculture ~3x3'. There are other patches of Eleocharis beneath the Polygonum bordering the area. Other species present but not in plot (in surrounding woods): Quercus phellos, Cypripedium sp., Lycopodium sp., Epigaea repens, Castanea pumila, Magnolia acuminata, Chimaphila maculata Fauna: downy woodpecker
