Observation Narrative	This plot captures a diverse and unusual assemblage of species along the edge of Walkerton Marsh, between a narrow zone of Nuphar advena and a dominance patch of Acorus calamus. The inland side of the plot lies along a subtle berm, which rises to an elevation ca. 20 cm higher than the marsh surface adjacent to the river. Plot dimensions were chosen to limit the inclusion of Acorus, but representation of species on the berm may overinflate richness. The incoming tide complicates complete identification of species present.
