Local 12: Nature still healing after Tristate storm that killed 4

It also knocked down countless trees in the hilly preserve. UC conducted four botanical surveys of the forest over the last 17 years to document its recovery.

Culley told WKRC-Local 12 that the clearings left behind by the storm gave nonnative Callery pear trees and Amur honeysuckle a chance to take over.

“We always assume nature will rebound and be OK,” she told Local 12.

But Culley said UC's study identified major differences between the damaged forest and the sections left untouched by the tornado.

Culley also spoke with WVXU about the study, published in the journal Ecology and Evolution. She told WVXU that active management of the preserve could benefit biodiversity.

“UC has owned this preserve since 1929. In the past it was really just hands-off, ‘let nature take its course,’” Culley told WVXU. “But we've realized within the last 10 or more years — since the tornado definitely — that we need to do a lot more. We need to be a lot more proactive.”

Some parks across Ohio are taking steps to eradicate plants like Amur honeysuckle to protect native flowers and ground covers that can get shaded out by the nonnative ones.
