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. Shrub encroached area just south of Shiawassee River. Evidence of previously healthy area just to northwest. Common species in area include Cornus foemina, C. sericea, Salix candida, Ulmus americana, Eutrochium maculatum, Carex stricta, Thelypteris palustris, and Typha latifolia. Ground hummocky and moist.
