Invasive Plants Banned in Ohio (Jan 2018; PDF | 276 KB)
Ohio Department of Agriculture.
In September of 2014, the Ohio General Assembly granted the Ohio Department of Agriculture (ODA) the
exclusive authority to regulate invasive plants species. Under the law invasive plants are defined as plant species
that are not native to Ohio whose introduction causes or is likely to cause economic or environmental harm, or
harm to human health as determined by scientific studies. After nearly two years of stakeholder outreach, new
rules have been established and are effective as of January 7, 2018.
For questions regarding Ohio's Invasive Plant Regulations, please contact the Plant Pest Control Program.
