Prairie fen complex on state and county land. Several small lakes and a man-made channel runs through it. The main complex is mostly sedge meadow and peat mounded seep. There is some encroachment by shrubs, trees, and a few invasives (Phragmites, Phalaris arundinacea, Rosa multiflora, Typha angustifolia, T. x glauca). There are also large colonies of Typha latifolia intermittant. Prairie fen dominated by Carex, Poaceae, and Asteraceae such as C. sterilis, C. bumbauxii, C. stricta, Solidago ohioensis, S. rugosa, S. uliginosa, S. altissima, Sorghastrum nutans, Schizachyrium scoparium, and Bromus ciliatus. Other prominent species include Dasiphora fruticosa, Toxicodendron vernix, Valeriana uliginosa, Apocynum cannabinum, and Thelypteris palustris. Some past management of woody cutting, invasive spraying, and burns. Evidense of recent burn in western patches. In western prairie fen patch, in southern section 70m north of southern border, on transition from tamarack wooded fen to open sedge meadow, 50m west of eastern border. Area dominated by Carex, Dasiphora fruticosa, Pycnanthemum virginianum, and Asteraceae with some Poaceae. Shrubs every 9m2 (Betula pumila, Toxicodendron vernix, Rhamnus alnifolia), more dense in Larix laricina area. Ground hummocky and water puddles in footsteps.
