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. Cyperaceae-dominated flat with abundant Dasiphora fruticosa. Cyperaceae include Eleocharis rostellata, Cladium mariscoides, Carex flava, C. sterilis, Schoenoplectus acutus, and S. pungens. Other species include Viola cucullata, Drosera rotundifolia, Muhlenbergia glomerata, and Parnassia glauca. Ground wet and somewhat marly.
