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.
