Observation Narrative
Resample of 13-year old permanent plot. Corners are now monumented with rebar stakes painted light blue.
This plot has changed only marginally since 2001. The two pitch pines recorded in the earlier sample are now dead, and a couple of additional Fagus grandifolia saplings have become established. Otherwise, floristic composition and relative species abundances have remained virtually static. Total basal area has increased only slightly, suggesting that tree growth is very slow on this dry, exposed site.
