Observation Narrative
Resample of 13-year old permanent plot. Corners are now monumented with rebar stakes painted light blue.
The habitat and vegetation of this diverse oak-hickory stand have not changed significantly since 2001. Two of the larger trees had parts of their tops blown out, but are still very much alive. The total basal area has increased slightly due the growth of trees, and total species richness has increased by nine taxa. Several potentially invasive exotics are present, including Alliaria petiolata, but still occur only at low (<1%) cover.
