Observation Narrative
Resample of 13-year old permanent plot. Corners are now monumented with rebar stakes painted light blue.
With the exception of one wind-thrown Quercus montana and another that died (still standing), all the larger trees recorded in 2001 were still present, and total stand basal area was almost identical to that of the earlier sample. The anthracnose fungus has claimed two of the four Cornus florida recorded in 2001. There have been mostly only minor changes to the low shrub and herbaceous flora, but a noticeable increase in the cover of Rubus phoenicolasius from <2% to >5% is problematic given the invasive tendencies of this shrub.
