Observation Narrative
Plot is located in Pond N105-11, aka "Sphagnum Pond", where Tom Rawinski sampled the transect GRAF032-036 in 1995. The present sample runs more or less perpendicular to this transect, capturing a single "zone" along the deepest elevation of the wetland. This pond is long and linear with an open forested canopy, mostly of Nyssa biflora. The water marks on the trees range from 33 to 50 cm above the ground surface. Carex joorii forms several fairly dense patches within the sample.
