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 northeastern portion of main section of prairie fen, 40m north of county-state property line, 60m west of upland border, north of a 6m tall Larix laricina and 5m south of L. laricina snag with Toxicodendron vernix growing underneath, 30m east of Phragmites stand. Cyperaceae, Poaceae, and Dasiphora fruticosa dominate with Lobelia kalmii and Solidago ohioensis. Ground hummocky and squishy when walking.
