Observation Narrative
Plot captures an openly forested swamp in large swale between back dunes. The basin was flooded (following heavy rains) to about 30 cm deep at time of sampling, but dense regeneration of Pinus taeda and Myrica seedlings in herb layer indicates that the habitat was dry for a considerable time recently. There are several dead trees in the wetland, but the cause of this mortality is unclear. Fairly abundant sapling and pole-sized regeneration of Acer rubrum and Nyssa sylvatica is restricted to the more shallowly flooded edges of the habitat.
