Observation Narrative	Plot location: south end of Riverbend Park, just north of south picnic area. Plot located in slight depression in floodplain supporting Acer saccharinum-dominated forest. Site is more frequently flooded than adjacent higher terraces. Overstory maples here are impressively large. 09/29/2003: revisited; site recently flooded by Hurricane Isabel and containing standing water and layer of silty mud.
