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. Typha latifolia dominated pocket on inundated and mucky ground. Other species include Caltha palustris, Toxicodendron vernix, Thelypteris palustris, Rumex orbiculatus, Larix laricina, and Impatiens capensis.
