Observation Narrative
Plot documents a nice example of a Coastal Plain seepage swamp on calcareous soils weathered from Miocene shell deposits. A mucky channel runs roughly down the middle of the plot, which utilized a linear (10 x 40 m) configuration to maintain homogeneity of habitat and vegetation. A canopy-sized Acer rubrum overhangs the plot.
