Observation Narrative	Swale occurs in a long, narrow interdunal depression parallel to the beach. Short-statured pines are scattered about in a moderately dense shrub understory. Boehmeria cylindrica is extremely abundant in the tall herb layer, while Toxicodendron radicans is common twining about shrubs. Creeping herbs occurring below the Boehmeria "canopy" include Hydrocotyle verticillata and Proserpinaca palustris. Pines in this area provide a moderately shaded environment. Pinus taeda in plot measured @ 16 cm dbh. Open swale to the north of plot supports Proserpinaca palustris, Diodia virginiana, Schoenoplectus pungens, Hibiscus moscheutos, Rubus sp., Convolvulus sp., Thelypteris, Lycopus virginicus, Apocynum cannabinum, Salix nigra, Cephalanthus occidentalis, Ptilimnium capillaceum, Fuirena pumila, Juncus canadensis and Galium sp.
