Lost Flora Fen

The 40 acre Lost Flora Fen is nestled along Raccoon Creek, northwest of Nygren Wetland Preserve (Rockton, Illinois) and near the Wisconsin border. Although not a true fen, a combination of low oxygen and acidic conditions in the soil reduces the availability of nutrients to plants, which allows a host of fen-loving species to thrive.

Naming this preserve the Lost Flora Fen came naturally, as not only had the northwind bog orchid (last seen in 1871) been lost to county records, but a suite of plant species first cataloged by Dr. Egbert Fell (father of NLI’s founder, George B. Fell) in 1947 had also been lost from the records until the recent inventory by NLI.  More than 250 native plant species, several of which are rare, threatened or endangered fen and sedge meadow species, as well as unusual butterflies and dragonflies were discovered.

This property was acquired in May 2018 through a bequest in memory of Veronica and her son Steven Cramer and a grant from Illinois Clean Energy Community Foundation. Also, with their support and other donors, NLI was able to install a sign, parking area and boardwalk.

Lost Flora Fen is open to the public. Access is on the east side of Sharp Road, .8 miles north of the intersection of Sharp Road and Yale Bridge Road, Rockton, Ill. Please follow all gate instructions

You may contact the NLI office with questions about directions and instructions for entering the preserve before your first visit: 815/964-6666, info@naturalland.org.
