Observation Narrative
Young floodplain forest along small secondary stream, just upstream from its confluence with the Rivanna River. This site was formerly cleared, and the current forest represents regeneration on abandoned agricultural/grazed land. The plot was positioned to exclude the largest colonies of exotic plants, at the cost of excluding several larger trees. Two large sycamores and one large tulip-poplar overhang the plot. Asimina triloba was just beginning to leaf out, but cover was estimated as if the plants were in full foliage. The cover of Claytonia virginica was probably higher in the early spring, and the cover of Verbesina alternifolia will undoubtedly be much higher in late summer/fall.
