Observation Narrative
Plot was placed on the convex brow of slope above siltstone cliffs along the Potomac River. A long, narrow configuration was used to capture a zone of relatively mesic and rich forest vegetation that occurs between the rocky and bouldery cliff face and bottom, and the dry sub-level upland above. This zone is characterized by a mixture of oaks, hickories, and sugar and black maples, with a relatively diverse herb layer that includes a number of nutrient-demanding species.
