Narrow fen at base of Quercus sp. Dominated upland. Water appears to seep out from base of upland and creates tranition/wooded fen zone at base. This occasionally gives way to high quality patches of fen, but much of the fen is overtaken by Lythrum salicaria and Typha spp. Area not likely to persist at prairie fen without management. Weedy area amidst shrub encroachment; about 10m south from woodland upland; ground moist; shrub encroachment by Sambucus sp. And lots of Toxicodendron vernix as well; common species in area include Phalaris arundinacea, Spartina pectinata, Onoclea sensibilis, Boehmeria cylindrica, and Symphyotrichum puniceum.
