Observation Narrative
The sampling site is on a high, well-drained floodplain terrace adjacent to the Potomac River. The vegetation is part of an extensive stand dominated by Platanus occidentalis (overstory), Acer negundo (subcanopy), Asimina triloba (shrub layer), and lush herbs. Mertensia virginica greatly dominated the herb layer at the time of sampling, but was beginning to evanesce.
