Very long heterogenous fen with marked spots of high diversity and other large weedy zones. Fen elevated on norther and southern margins and depressed near central lakes (2). Bordered on north by woodland as well as on southern edge, but southern edge has a railroad and nearby row-crop agriculture. Typhaspp. appear to be heavily impacting fen. Carex stricta dominated area with Cornus sericea, Thelypteris palustris, and Agrostis gigantea. About 10m from flooded area adjacent to Shiawassee. Typha latifolia dominates nearby. Quadrat about 20m north of woodland.
