Ohio Invasive Plants Council.

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.
