Observation Narrative
Small patch of undisturbed forest with old white oaks and younger cohort of red oak and hickories. Graminoid-rich herb layer is dominated by Carex pensylcanica. A gap in the NW corner of the plot (from large red oak snag just outside plot) reduced the canopy coverage. On the other side of Rt 691 is a more extensive patch of the same vegetation that has been thinned and has a more savanna-like structure.
