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 dominated by Asteraceae and Thalictrum dasycarpum. Encroaching shrubs include Frangula alnus and Betula pumila. Common species include Doellingeria umbellata, Euthamia graminifolia, Solidago gigantea, Lathyrus palustris, and Galium boreale.
