Large zone of Cyperaceae dominated inundated flat near Long Lake. Appears many people drive vehicles through it. On the edges and to the west is the sedge meadow, calcareous seep, or wooded prairie fen. The area on the west side is practially saturated with Sphagnum moss mounds and Toxicodendron vernix. Other prominent vegetation includes Larix laricina, Thelypteris palustris, Dasiphora fruticosa, Solidago patula, Carex, and Scheonoplectus. Also contained Drosera rotundifolia, pitcher plants, and Eriophorum. Some invasion by Frangula alnus. The southern portion of the fen is colonized by Typha angustifolia, T. x glauca, and Lythrum salicaria until the 2m wide channel. South of the channel has less dense L. salicaria and little T. angustifolia or T. x glauca. In most southeastern sliver of prairie fen, 25m south of Long Lake, 2m east of two 5m tall Ulmus. Carex and Asteraceae meadow invaded by Lythrum salicaria and encroached by shrubs of Toxicodendron vernix, Cornus, and Salix. Ground hummocky and wet, standing water in quadrat.
