This 521-acre property is a dedicated state nature preserve located in Springfield Township and Michigan City. The flatwoods ecosystem harbors relict populations of several plant species that are typical of more northern latitudes. Ambler is the largest Shirley Heinze nature preserve. It is largely forested, with a rich herbaceous flora. In early spring, vernal pools and rivulets cover a great portion of the property. The dense, thick woods provide habitat for 39 state-listed plant species and 40 plants considered rare in the Chicago Region (as determined by Swink & Wilhelm in Plants of the Chicago Region). There are four miles of hiking trails departing from two trailheads/parking areas on Meer Road and County Road 900 North.

During the evening hours in early spring, the woodland ponds at Ambler come alive with a choir of calling frogs. Tiny chorus frogs and spring peepers – neither larger than an inch and a half in length –call for several weeks. The somewhat larger wood frog joins in for just a few days. Their appearance is a sure sign that spring’s annual rebirth is fully underway.
