Observation Narrative
A small, undistirubed Shenandoah Valley sinkhole pond supporting pin oak woodland vegetation typical of many such ponds. Water marks on the trees indicate that seasonal flooding depth is about 60-65 cm, and the wetland was only recently drawn down on the survey date. Small colonies of buttonbush occur along the southern margins of the pond. Only a few herbaceous species were present; only Eleocharis acicularis, Panicum rigidulum var. rigidulum, and P. verrucosum had appreciable cover.
