Observation Narrative	This plot is located in a sheltered cove on the Potomac River floodplain, at the mouth of a narrow, high-gradient ravine. The floodplain is likely built on an alluvial fan and slopes noticeably from the base of the adjoining, boulder-covered slope to the river. The vegetation is dominated by Acer negundo in all tree layers, by Asimina triloba in the shrub layer, and by a massive clone of Matteuccia struthiopteris var. pensylvanica in the herb layer. A number of other nutrient-demanding forbs occur at low cover under the Matteuccia. A very large Ulmus americana (approximately 150 cm DBH) is located just outside, and overhangs, the plot.
