Observation Narrative	The plot is located on a slope fronting the Potomac River floodplain in Riverbend Park. The forest here is much "richer" in appearance that most other mesic forests of Riverbend Park; uncharacteristically high calcium and magnesium levels in soils samples and the presence of nutrient-demanding species such as Carex careyana, Allium tricoccum, Dicentra canadensis, and Hydrophyllum canadense quantify this difference. The overstory is dominated by very tall and mature Fagus grandifolia and Liriodendron tulipifera. In the summer, this site has a very dense shrub growth of Asimina triloba. In the spring, Claytonia virginica carpets much of the ground.
