Observation Narrative
Plot is in ravine in SW corner of Park, W of Gill's Creek. It is on slope above a small creek. The forest is not typical of the area and unique in its rich flora. Dark rocks are present at the surface and the vegetation seems to reflect an ultramafic influence.
Patch dominants are Hydrastis, Adiantum, and Deparia. Canopy and subcanopy are mostly Liriodendron and Fraxinus with scattered individuals of Quercus rubra, Juglans nigra, Carya cordiformis. The shrub layer is predominately Asimina and Lindera. The forest surrounding the sample has more Magnolia acuminata than reflected in the sample.
