Invasive species are non-native species which reproduce and spread rapidly, causing major disturbance to wildlife and change the balance of the ecosystem. Usually the reason for the unintentional introduction of these pests is due to human global trade. The Nature Conservancy estimates that damage from invasive species totals more than 1.4 trillion dollars worldwide, or 5% of the global economy!

In the news

As some of you may have heard a colony of spotted lanternfly, an invasive and highly destructive tree hopping insect, was found in Mingo Junction in Jefferson County. The first report was from a citizen on October 19th. Ohio Department of Agriculture employees found more nearby.
SLF is a great concern to the grape and wine industry. The insect is fond of grapevines, fruit trees, hops, blueberry, oak, pine, poplar, and walnut. Adult SLF are attracted to the invasive Ailanthus tree, also known as tree-of-heaven, while nymphs feed on a wide range of hosts. Both adults and nymphs feed on stems and leaves, causing sap bleeding and reduced photosynthesis, which can eventually kill the plant.
The public is the first line of defense against the SLF. If you believe you have seen an SLF in your area, you can easily report a suspected infestation by going to ODA’s Spotted Lanternfly Information Page and filling out a suspected infestation report. You may also call the Plant Pest Control Division at (614) 728-6400.

For more information, access the Ohio Department of Agriculture’s web page on invasive species HERE. Central Ohio Partnership for Regional Invasive Species Management, or more commonly referred to as PRISM, is a 17-county partnership geared towards detection, education, and eradication of invasive species. More about this coalition can be found on the website The Ohio Invasive Plants Council is a non-profit organization that promotes public awareness of invasive species. The OIPC website has a lot of resources and information about invasive species. It can be accessed HERE. The Great Lakes Early Detection Network (GLEDN) is an invasive species early detection and warning system for the Great Lakes region. It relies on users to download the app and report sightings while they are out in nature. Download the app HERE.
