Observation Narrative	Narrow band (not much more than 5 m wide) of Schoenoplectus americanus adjacent to main channel of Rappahannock River. Vegetation is reminiscent of linear communities in similarly low intertidal zones of the Pamunkey River and side channels; such stands characteristically contain Pontederia cordata, Schoenoplectus tabernaemontani, and S. pungens, but occur under strictly freshwater conditions. This site is undoubtedly oligohaline. Water depth measured 41 and 13 cm at corners 1 and 4, respectively, at 12:25 PM.
