Observation Narrative
This is a very small upland depression swamp developed on a level upland with hardpan subsoil. A 200 sq. meter plot was sampled in an attempt to keep the quadrat environmentally homogeneous. Nevertheless, the inclusion of some upland elements along the edges was unavoidable. The forest vegetation is characterized by a strong dominance of Quercus phellos, with rather open or sparse shrub and herb layers.
