Observation Narrative	Resample of 13-year old permanent plot. Corners are now monumented with rebar stakes painted light blue. Since the original 2001 sampling, three dominant oaks have died, one of them creating a large canopy gap in the southwestern part of the plot. Unlike many stands on Bull Run Mountain where oaks are decadent, this one nearly lacks Acer rubrum in the understory and most of the younger tree recruitment consists of hickories (Carya ovalis and Carya tomentosa). Very heavy levels of deer herbivory continue to suppress the cover and vigor of herbaceous plants in this plot.
