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. Cornus sericea encroached hummocky area with Dasiphora fruticosa, Carex sterilis, Pycnanthemum virginicum, Solidago altissima, and S. patula. Quadrat about 4m south of lone Juniperus virginicus. Some Frangula alnus in area; ground moist between hummocks.
