Observation Narrative	GPS data could not be obtained at this plot, but the site was easily mapped using topographic features. The habitat is a concave, NNE-facing lower slope just above the broad Potomac River floodplain at the east end of Scotts Run Nature Preserve. The sheltered aspect and fertile soils support very lush mesophytic forest vegetation with a mixed overstory of Acer saccharum, Fagus grandifolia, Tilia americana, and Fraxinus americana. The herb layer is spectacular in the spring, with dense colonies of Allium tricoccum, Podophyllum peltatum, Erythronium americanum, Caulophyllum thalictroides, Hydrophyllum canadense, Claytonia virginica, Dicentra canadensis, and many other early-maturing species.
