Kitty Todd Preserve is one of the finest nature preserves in the Oak Openings region of northwestern Ohio. The Oak Openings region was originally characterized by a series of windblown sand dunes and wetlands that were saturated in winter and spring and extremely dry in summer. These conditions gave rise to vegetation ranging from dry sand barren and oak savanna on the raised dunes
Frosted Elfin: The frosted elfin is another of Ohio's endagered butterlies that feeds on blue lupine. It was never totally eliminated from the Oak Openings, and seems to be doing better with increased stands of its larval host, due to Karner blue conservation efforts.
