Observation Narrative
The area sampled is in a backswamp slough adjacent to a disturbed upland, ca. 250 meters from the main channel of the Nottoway River. The area was dry on the date of sampling, but holds water, in places deeply, for a significant part of the year. The canopy is mostly Nyssa aquatica, mostly 40-50 cm diameter, but with some individuals approaching 1 meter in diameter. Nyssa biflora is present in the subcanopy. The ground cover is mostly litter with some patches of graminoids and forbs.
