Observation Narrative ? A moderately diverse stand of low marsh dominated by Pontederia cordata and Leersia oryzoides, with a significant component of Murdannia keisak and an unusually large number of emergent stems of Scirpus cyperinus. Scattered individuals of Cephalanthus occidentalis, many of which appear dead (see Plot Narrative for plot PAMR014), surround plot on three sides. A single individual of Nyssa biflora (ca. 4 m tall) stands just outside plot and contributes a trace of overhanging cover. Plot permanently marked with PVC stakes.
