Varieties of this community occur along higher gradient sections along the Bluestone. Mostly upstream from this plot. Down stream 50 meters is a narrow Betula nigra / Diospyros virginiana - Carpinus caroliniana / Verbesina alternifolia woodland (BLUE.13). On the older terrace above the plot is an early successional forest dominated by Quercus velutina and Lriodendron tulipifera (BLUE.14).;Lots of flooding this season. This was the site of a collection earlier in the season. The area seemed more diverse during the previous visit. All plants are bent over from this seasons flooding.
