Observation Narrative	Plot in a backswamp forest of the Dragon Swamp bottomland, extending from the upland edge to about 50 m from the main channel. The stand is dominated by Taxodium distichum of multiple age classes, with a few trees up to ca. 1.0 meter DBH and knees 0.5-1.0 m tall. A younger cohort of Acer rubrum forms most of the understory. The shrub layer is open and the herb layer is patchily dominated by Saururus cernuus. Moss covers the base of trunks and fallen logs. This is one of the nicer baldcypress swamps along the Dragon.
