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. Very moist ground dominated by Cyperaceae and Dasiphora fruticosa. Cyperaceae include Schoenoplectus acutus, Carex sterilis, Cladium mariscoides, and Carex lasiocarpa. Eleocharis elliptica present. On northwest edge of dense Larix laricina/Toxicodendron vernix thicket. Moss layer on ground.
