Kaufmann Avenue Prairie features rugged, rocky ridgetops with an expanse of native hill prairie.
The preserve is a "goat" or hill prairie, which occurs on steep, thin soils with a south-southwest exposure. The best examples occur here in northeast Iowa’s Paleozoic Plateau, but similar prairie can be found in other parts of the state. "Goat" prairie refers to the steepness of the slopes, on which only goats could be expected to graze.
The purchase of Kaufmann Avenue Prairie from the William Connery Estate was made possible by a donation from Dr. John Brennan, who was instrumental in helping to protect this site. The nearby quarry is reported to have been used for hibernation by the state-endangered Indiana bat.
