Invasive species pose significant threats to Ohio’s ecosystems, economy, and public health. These non-native organisms disrupt natural habitats, outcompete native species, and can lead to substantial economic losses. Understanding the specific challenges Ohio faces and implementing effective management strategies are crucial for preserving the state’s natural heritage.
Invasive Species in Ohio: An Overview
Approximately one-fourth of the plant species in Ohio are non-native, with fewer than 100 identified as invasive in natural areas. These invasive species can cause extensive economic damage and harm to Ohio’s natural resources. (misin.msu.edu)
Notable Invasive Species in Ohio
- Emerald Ash Borer (Agrilus planipennis): This beetle has devastated ash tree populations across Ohio, leading to significant ecological and economic impacts. (aphis.usda.gov)
- Spotted Lanternfly (Lycorma delicatula): First reported in Ohio in 2024, this pest threatens various plants, including fruit and ornamental trees, by causing wilting, leaf curling, and dieback. (axios.com)
- Asian Longhorned Beetle (Anoplophora glabripennis): This beetle attacks hardwood trees, including maples and birches, posing a significant threat to Ohio’s forests. (aphis.usda.gov)
- Regulation and Legislation: Ohio has established regulations to control the spread of invasive species. The Invasive Plant Advisory Committee, created under Rule 901:5-30-02 of the Ohio Administrative Code, advises on matters regarding invasive plants, including identification and establishment of prohibited activities. (codes.ohio.gov)
- Public Education: Educating the public about the risks associated with invasive species and promoting responsible practices, such as not transporting firewood, can prevent the spread of these pests.
- Monitoring Programs: The Ohio Department of Natural Resources (ODNR) conducts regular surveys to detect invasive species early. For example, the recent discovery of the elm zigzag sawfly in Franklin and Delaware counties highlights the importance of vigilant monitoring. (axios.com)
- Reporting Mechanisms: Residents are encouraged to report sightings of invasive species to ODNR’s Division of Forestry at 614-265-6694 or through the Great Lakes Early Detection Network app.
- Management Plans: ODNR develops and implements management plans for invasive species, focusing on control and eradication efforts. These plans often involve a combination of mechanical removal, chemical treatments, and biological control methods.
- Collaboration with Partners: ODNR collaborates with federal agencies, local governments, and non-profit organizations to coordinate efforts in managing invasive species. The Ohio Invasive Plants Council, for instance, works to address the threats of invasive species through stewardship, education, research, and information exchange. (oipc.info)
- Volunteer Opportunities: Ohio residents can participate in invasive species removal projects organized by various organizations, including The Nature Conservancy and local Metroparks. These projects often focus on removing invasive plants like honeysuckle and garlic mustard. (oipc.info)
- Educational Programs: The U.S. Fish & Wildlife Service offers outreach and education programs on invasive species, providing resources and presentations to schools, government agencies, and non-profit organizations. (fws.gov)
- Stay Informed: Learn to identify invasive species common in Ohio and stay updated on new threats.
- Report Sightings: If you encounter an invasive species, report it to ODNR’s Division of Forestry at 614-265-6694 or through the Great Lakes Early Detection Network app.
- Participate in Local Efforts: Join local invasive species removal projects or educational programs to contribute to statewide management efforts.
- Practice Responsible Behavior: Avoid transporting firewood, clean your hiking boots and equipment to prevent the spread of invasive species, and choose native plants for your garden.

Impact on Ohio’s Ecosystems and Economy
Invasive species disrupt natural habitats, leading to the decline of native species and altering ecosystem dynamics. Economically, they affect agriculture, forestry, and tourism. For instance, the emerald ash borer has led to the removal of millions of ash trees, costing Ohio communities millions of dollars in tree removal and replacement.
Management Strategies in Ohio
Effective management of invasive species in Ohio involves a combination of prevention, early detection, rapid response, and public engagement.
