Observation Narrative
Plot documents an old-age Taxodium distichum - Nyssa aquatica stand occurring in a floodplain slough ca. 100 meters from the main channel of the Nottoway River. Although a larger quadrat could have been sampled, the 400 square meter plot captures a good representation of the stand, which has overstory trees up to ca. 250 cm DBH and 30 meters tall. The understory and shrub layers are very open, and the herb layer is fairly dense on slightly elevated hummocks around the bases and knees of the massive bald cypress trees.
