Observation Narrative
Small, diverse pocket marsh occupying ca. 0.1 ha and dominated by Pontederia cordata, Eleocharis quadrangulata, Polygonum punctatum and Zizania aquatica. Stand bordered by Alnus serrulata thicket, which forms fringe along river, and interior tidal hardwood swamp forest. Some dead stems of Fraxinus are present in the plot. Horizontal zonation is evident; Polygonum is more abundant near the Alnus (and in plot), and Pontederia increases toward the swamp forest. A small, lower bed of Nuphar advena lies along drainage channel outside of plot.
