This is a very thin community surrounded by oak/heath.;This is a colluvial (alluvial?) feature where large boulders fill a depression which appears to be an intermittent run/gully. The rck layer here is very deep with large void spaces and favors Betula, Nyssa and Fraxinus. The only ground layer is vines and woody seedlings.
