Observation Narrative
Plot encompasses the upper slope/ crest transition zone on a sharp ridge bordering the inner edge of the Potomac River floodplain above Great Falls. Vegetation in the plot is a mixed oak-hickory forest with Fagus-dominated understory and sparse herb layer. Carya spp. and Asimina triloba dominate the steeper slope of this ridge just below the plot. Small outcrops of micaceous rocks are present near the plot.
