Observation Narrative	A Pinus taeda - Quercus spp. dune woodland, apparently being eroded away by wave action. Crest of dune is 1.04 m above water level in adjacent bay at time of sampling, when tide is somewhere between low and high. Pine needle duff is quite deep on back slope of dune toward bottom of slope. Width of plot is < 10 m narrower than width of community. Plot located in dune woodland on side of marshes. Midpoints of two short segments of plot rectangle are marked with 1" diameter PVC pipe. Long axis runs at bearing of 152 deg.
