Invasive Species Resources

This interactive database contains information on the plants currently included in the Cal-IPC Invasive Plant Inventory. The Inventory categorizes plants as High, Moderate, or Limited, reflecting the level of each species' negative ecological impact in California. Includes options to search for species by region and by habitat type. The database provides a better view of information on each species and allows users to download the entire Inventory as a spreadsheet.

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. 

The Oklahoma Invasive Plant Council has developed a list of invasive plants by region. These plants have invasive qualities and are present in the region or neighboring regions. These are species that are not abundant yet in the area, but should be monitiored, reported and controlled before they become a bigger problem in the state.
