Observation Narrative	The downstream end of Walkerton Marsh consists of a mosaic of vegetation patches dominated by Zizania aquatica and Pontederia cordata. This plot, at the interior end of transect #5, captures the interdigitation of these two types. An extensive zone of Pontederia begins ca. 10 m upstream from the plot (across boardwalk) and is bisected by at least one prominent tidal channel. One plastic bottle was floating in the plot. Water depth ca. 28 cm at time of sampling; low tide was unusually high following Hurricane Dennis.
