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, 60m east of wooded gully near aspen grove, 200m north of southern border. Area dominated by Carex and Asteraceae with some Calamagrostis canadensis and Phalaris arundinacea. Shrubs infrequent and those 2m or less have signs of burning. Also amount of dead vegetation on ground is less than usual. Ground hummocky and wet.
