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 southwestern-most portion of fen, 15m east of Long Lake, 20m north of shrubby southern border, 100m south of Lythrum salicaria channel. Sedge meadow transitioning into wooded prairie fen, then shrubby border. Area dominated by Carex, Asteraceae, and Thelypteris palustris. Iris and Apocynum cannabinum common. Underneath quaking aspen trees. Cornus and Toxicodendron vernix shrubs and saplings common very 1-4m2. Ground hummocky and puddles in footsteps.
