Observation Narrative
Quillen Pond #2 of Hayslett report. A relatively dry pin oak / panic-grass sinkhole pond covering ca. one acre, with extensive recent pin oak mortality; also extensive pin oak seedling recruitment. Plot runs across center of pond, and mostly avoids a dense patch of herbs in the deepest portion under dead oaks. There is one large snag and one small snag in plot. Several hundred clones of Carex polymorpha occur in a dense colony along the south edge of the pond. At least one very old, shallow ditch is present.
