Gray-Hart Memorial Preserve


This preserve is home to several rare fen plants.

Gray-Hart Preserve is one of the state’s largest fens, which is a type of wetland that tends to be marsh-like in nature. This area is a wonderful addition to the preserves found in Iowa.

Walking in this area has been described as feeling like walking on a waterbed.  These fens - basically areas of extremely spongy and water-filled land - are beautiful as well as intriguing because of their unique array of plant life.

Gray-Hart Preserve is one of the largest fen wetlands in the state and hosts a multitude of rare fen plants. The Conservancy obtained this site through a bargain sale from Marty Mihall and named it in honor of her parents.

The Conservancy has partnered with Fayette County Conservation Board to help manage the site. An access road, which allows public access to the preserve to the site, thanks to the support of Marty Mihall.
