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 patch of prairie fen, on the south portion, 90m north of southern border, 50m south of wooded gully, 10m east of two 10-12m tall stand alone Larix laricina trees. Burned shrubs and little dead vegetation on ground indicates a recent burn. Shrubs every 25-36m2. Saplings under 1m every 9-25m2. Ground hummocky and wet, puddles in footsteps. Dominant vegetation includes Carex, Eutrochium maculatum, Solidago patula, Thelypteris palustris, and Valeriana uliginosa.
