Secor Metropark is at the north end of the Oak Openings Region. This region sustains a mosaic of natural communities, making it a place of high biodiversity. The forest in this park is approximately 75-150 years old and covers 159 acres. The tree species include tupelo, silver maple, sycamore, cottonwood, hickory, beech, as well as red, pin, and white oak. This protected natural area is home to a variety of wildlife, including deer, fox, coyotes, reptiles and amphibians, woodpeckers, both migrating and nesting songbirds, raptors, as well as grassland nesting birds. Spring wildflowers such as trillium, wild geranium, wild ginger, bloodroot, and jack-the-pulpit can easily be viewed along the trails in the rich woodlands. A focal point for visitors at Secor Metropark is the National Center for Nature Photography, where educational programs, interpretive displays and photography exhibits are offered.
