The Michigan Department of Agriculture and Rural Development (MDARD) is seeking public feedback on two significant invasive species proposals through Monday, Feb. 9, 2026.

1. Proposed Invasive Plant Species Changes

MDARD is proposing to update the Michigan Prohibited and Restricted Species List to include six new plant species identified as potential threats to the state’s environment and economy.

1. Prohibited (Highest Risk): Water-hyacinth and water lettuce.
2. Restricted (Established but Invasive): Callery pear (including Bradford pear), Japanese barberry, common buckthorn, and glossy buckthorn.
3. Regulations: If approved, it will be illegal to import, sell, or intentionally transplant these species. For restricted species, the proposed ban on sale and cultivation would not take effect until January 1, 2028.
4. Submit Comment: Use the Invasive Plant Species Online Survey.

2. Proposed Exterior Firewood Quarantine

This order aims to protect Michigan's forests from over 140 invasive pests and diseases, such as the

Asian longhorned beetle and spotted lanternfly, which can be transported via untreated firewood.

1. Proposed Restrictions: Restricts all firewood entering Michigan from other states unless it is heat-treated and certified.
2. Exemptions: Proposed exceptions include kiln-dried lumber, small wood chips (under 1 inch), and logs destined for immediate industrial processing.
3. Note: This quarantine does not apply to locally sourced Michigan firewood.
4. Submit Comment: Use the Proposed Firewood Quarantine Online Survey.
