United States, Michigan, Oakland, Long Lake Fen
285 meters (935ft)
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. Populus tremuloides grove with Cornus foemina. Equisetum arvense and Carex aquatilis make up most of the herbaceous layer along with Agrostis gigantea, Apios americana, Pycnanthemum virginicum, Thelypteris palustris, Solidago altissima, and Symphyotrichum puniceum. Ground moist.
