Located in a rapidly growing area of Liberty and Orange townships, Big Run Preserve is named for the head water habitat stream – a tributary to the Olentangy State Scenic River – that runs through the park and supports important plant and animal species.
The Big Run stream winds along a twisting corridor consisting of 20 to 40-foot-tall shale cliffs and a stream bed. You can see many remnants of concretions (round rock formations) in the cliffs and along the stream bed. There are also intermittent waterfalls in the park.
Visitors will see a mature white oak forest in the eastern half of the park, along with large stands of hickory and maple. Spring wildflowers include the large white trillium, blue cohosh, and yellow-trout lily. Wildlife you might encounter include: a large assortment of birds, such as barred owls and pileated woodpeckers; migrating neo-tropical songbirds, such as the hooded warbler and Acadian flycatcher; whitetail deer, raccoons and coyotes; and amphibians, such as the two-lined salamander.
Of the 183 total acres, 123 acres were acquired over several years including 2010, through a combination of park levy funds, grants and a loan from the Ohio Environmental Protection Agency. The other 60 acres were acquired in 2004 with funding from the Ohio EPA.
