Keeping Invasive Trees Out of Ohio

heracleum mantegazzianum

Ohio’s Department of Agriculture has passed a law aimed at keeping invasive species out of Ohio. A list of illegal species now exists, and officials will be inspecting garden stores and nurseries to make sure nobody is selling these forbidden flora and fauna.

An article in the Columbus Dispatch goes into detail about the origins of the law and the ways it will be enforced.

To prevent you from getting into trouble, we want to publish the full list, so that you know exactly what to avoid. Tree removal companies in Cincinnati and throughout the state will be on the lookout as well.
