Savage Fen SNA and Seminary Fen SNA: Calcareous Fens, Sedges and Orchids
See two gems of the Lower Minnesota River Valley consisting of sloping, calcareous, organic soil wetlands with springs and small, groundwater-fed, marl streams. Fifteen members of the sedge family, including 10 species of Carex, as well as the exquisite white lady's-slipper orchid, are anticipated highlights. Such floristic diversity in the heart of a large metropolitan area is rare. Problems with invasive species (buckthorn, Phragmites, hybrid cattail) will be discussed. Of particular interest will be observing the results of a prescribed burn conducted last spring at Seminary Fen SNA.
