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. Western portion of main fen complex, 125m east from western border, 100m south of lake in transition zone from sedge meadow and Cyperaceae zone to Typha stand. Area dominated by Carex, Asteraceae, and Dasiphora fruticosa with Typha and Schoenoplectus. Shrub saplings every 1m2 and shrubs over 2m every 25m2 (Cornus, Toxicodendron vernix). Ground hummocky and puddles in footsteps.
