Wetland includes several sedge communities, Alder swamp, cinnamon fern beaver burn, St. Johnswort shrubland, and Solidago herb types.;Low terrace behind a breached beaver dam with a meandering stream. The low banked stream frequently floods this community. Soft fine sediment with some more course inclusions along the streamlet. Patchy dominance by Eleocharis, Sparganium, and Leersia oryzoides. Abundant driftwood from past beaver burn.
Representativeness
