The Strib published a story today about Seminary Fen, located in the Minnesota River valley in Chaska. The rare calcareous fen has been acquired by the DNR and will become a scientific and natural area. The fen was formerly privately owned and environmental groups have advocated for its protection for years. It is still threatened by development in the area and a new bridge over the Minnesota River that may be built on the wetland.
