Michigan Commission Adds Six Species to Invasive Plant Lists, Affecting Statewide Regulations
The Michigan Commission of Agriculture and Rural Development has decided to add six plant species to the state's invasive plant lists under Part 413 of the Natural Resources and Environmental Protection Act. This decision, made on May 20, 2026, follows a comprehensive scientific review process conducted by the Michigan Department of Agriculture and Rural Development. The review, which began in November 2025, included Weed Risk Assessments and public consultations, receiving over 2,000 comments, with more than 90% in favor of the additions. The new regulations will make it illegal to introduce, import, sell, or propagate these species in Michigan, with two species becoming prohibited as of June 19, 2026, and the remaining four by January 1, 2028.
