A wide variety of Carex fruiting, but few Toxicodendron vernix and the ones seen are usually under 1m. Many rivulets and holes (I fell upto my hip). Not as peaty as other prairie fens in most places. Some management in the northern section by NOHLC, a burn several years ago and woody plant removal. In northern marl zone of fen, 40m from eastern border, 80m south of entrance. Cyperaceae and Dasiphora fruticosa dominate marl area with invasion of Typha angustifolia. Ground +/- even and wet (grey).
