Observation Narrative
Plot captures forest around rim and edge of a small semi-open pond (Pond SROW-X) of the Grafton Ponds complex. Most of the plot lies on slightly higher ground than the pond basin, and is only shallowly seasonally flooded (water marks absent). The vegetation is characteristic of the more mature, second-growth forests that occupy the shallowly flooded ponds and depressions in the area. Quercus phellos is the most important canopy species in a mixed stand with Liqiudambar styraciflua, Acer rubrum, Quercus alba, Q. pagoda, and a little Pinus taeda. The shrub and herb layers are open, the former consisting mostly of tree saplings and Vaccinium fuscatum, the latter consisting mostly of graminoids (Chasmanthium laxum, Carex joorii, Carex albicans var. emmonsii). Sphagnum mosses are present, but cover <1%.
