Observation Narrative
Plot located in a poorly drained section of the Bull Run floodplain. The habitat of the plot is subject to shallow seasonal flooding; however, between the plot and a bluff at the inner edge of the floodplain is a deeper swale that holds water longer and contains abundant Saururus cernuus. Wet-site sedges and grasses dominate the herb cover in the plot, beneath a canopy of Fraxinus pennsylvanica and Quercus palustris, and an understory consisting largely of Acer negundo.
