Observation Narrative
Plot documents an upland depression swamp in flatwoods over Triassic siltstone. The swamp is bisected by a gasline right-of-way and the plot was positioned on the NW side of this clearing to capture the larger fragment of this habitat. The stand has a mixed overstory of Quercus palustris, Q. bicolor, Q. phellos, Acer rubrum, and Fraxinus pennsylvanica, all of which have excellent recruitment in the understory. Viburnum prunifolium is the leading shrub and sedges form most of the rather sparse and patchy herb layer.
