Pests & Diseases

Don't Move Firewood

In an effort to protect the trees of Ohio from multiple pest infestations that threaten the health and viability of the state’s hardwood forests, the movement of firewood and certain tree products is tightly regulated by both state and federal authorities in Ohio. 

In Butler County, the movement of nearly all types of hardwood products is prohibited. Regulated materials that should NOT be removed from Butler County include hardwood nursery stock, unprocessed lumber, or any other type of hardwood material, such as logs, stumps, roots, branches, mulch, wood chips, or any firewood (including firewood that is kiln-dried, seasoned, or green).
