Observation Narrative	Extraordinarily soft substrate precluded complete sampling of this plot as it was originally laid out, and time prevented its reconfiguration, so data were collected from a true releve. Species list compiled and cover values estimated based on examination of perimeter of an area approximating 100 sq. m, but completeness and accuracy cannot be guaranteed. Vegetation here is extremely robust -- Bidens laevis grows to 2 m and Zizania aquatica to nearly 3 m -- and is almost impenetrable in places.
