Observation Narrative	Plot represents a low marsh freshwater tidal type dominated by Schoenoplectus fluviatilis and Sagittaria latiflora. Area has bands of Schoenoplectus running throughout with some Typha along edge. Adjacent to lower Nuphar stand (in narrow channel) and transitions into more Typha/Impatiens type on other side of Nuphar channel. Dominance by Sagittaria seems unusual for Dyke Marsh.
