Observation Narrative	Plot captures a long, low, first bottom immediately adjacent to the Potomac River. The habitat is scoured or inundated several times per season. Open forest vegetation is dominated by large Acer saccharinum, with a scattering of Platanus occidentalis. The understory is very open over most of the plot, but a dense Asimina triloba thicket at the upper edge (away from the river) increases the overall shrub cover.
