Observation Narrative	An "upland depression swamp" forest, dry on the date of sampling but shallowly and irregularly flooded with perched groundwater during the winter and spring months. The stand is exceptionally mature, with Quercus palustris (pin oak) and Quercus bicolor (swamp white oak) up to ca. 90 cm DBH dominating the overstory. Oak recruitment is poor and greatly outnumbered by that of Acer rubrum (red maple), Fraxinus pennsylvanica (green ash), and Ulmus americana (American elm). Climaceum americanum (American tree moss) is the dominant bryophyte on seasonally wet hummocks. This stand is one of the larger (~ 5 acres) extant occurrences of this community type known in Virginia. It is thinly buffered by a narrow stand of oak-hickory forest on both adjacent slopes. Exotics, particularly Microstegium vimineum, are present in large numbers in adjacent disturbed habitats.
