Observation Narrative	The plot is in a maritime dune woodland dominated by short-statured loblolly pines. It grades toward the bay into scrub and grassland. Inland is similar vegetation but with taller trees and more stable sand. The woodland vegetation covers about 66 acres. Dune grasses (especially Schizachyrium littorale) and sand-loving xerophytes such as Cyperus grayi, Polygonella articulata, and Hudsonia tomentosa form a rather sparse herb layer.
