Kinnikinnick Fen is a 154 acre wetland complex situated along Kinnikinnick Creek in Green Township. A "fen" is a type of wetland (along with bogs, swamps, and marshes) that is fed by spring water that is mineral rich and alkaline, rather than containing the acidic water that you find in most of the other wetland types. As a result of the unusual alkaline water chemistry, several threatened plant species are found here, along with a couple of Ohio Threatened animals...Kirtland's snake and the Spotted turtle.
The preserve features a 1.8 mile walking path that follows Kinnikinnick Creek and passes through
wetlands and sedge meadow, woods, and fields of wildflowers and native grasses that were formerly in
agriculture. Three observation decks offer wonderful views of Kinnikinnick Creek and oxbow wetlands.
