Keeping invasive pests out of Michigan starts with firewood

3 min read

It should have come as absolutely no surprise to anyone paying the least amount of attention, a recent state decision to quarantine out-of-state firewood as one viable way to battle invasive species and plant diseases.

But beginning Jan. 1, that’s what’s going to happen. From where we sit, it’s a great idea and one that has significant scientific underpinnings.

The new policy was announced by the Michigan Department of Agriculture and Rural Development and the Michigan Invasive Species Program. Firewood may look harmless, but it can harbor pests and pathogens that are difficult to detect and even harder to control once they become established in a new area.

The consequences can be devastating. Invasive species threaten native trees, disrupt ecosystems and impose costly burdens on landowners, businesses and public agencies. Michigan's forests are too valuable to leave unnecessarily exposed to these risks. Preventing an infestation before it takes hold is a far more practical approach than spending years and substantial resources trying to contain one.

Under the new rules, untreated firewood from outside Michigan will no longer be allowed into the state. Properly heat-treated firewood carrying the required certification or authorization will remain permissible, along with certain exempt wood products. This approach recognizes that people still need access to firewood while establishing safeguards against the movement of harmful pests.

The policy also builds on Michigan's Invasive-Free Firewood Certification Program, which allows qualifying producers to label properly heat-treated products with a "Certified Invasive-Free" seal. Consumers can support prevention efforts by looking for this certification when purchasing firewood.

Of course, the success of the quarantine will depend on more than a new rule. Education and public cooperation will be essential, particularly among campers, hunters, tourists, seasonal residents and businesses that transport or sell firewood. The state has indicated that implementation in 2027 will focus heavily on education and awareness, giving people an opportunity to understand the requirements and adjust their habits.

Travelers should plan ahead, check the rules before crossing state lines with firewood and purchase wood near their destination whenever possible. Campgrounds, retailers and tourism-related businesses can also help spread the word. These simple steps can make a meaningful difference in keeping invasive species from hitching a ride into Michigan.

Michigan is not alone in taking this approach. States including Minnesota, New York and Wisconsin have adopted restrictions intended to reduce the spread of invasive pests through firewood. Requirements differ, so travelers should consult resources such as Firewood Scout before transporting wood across state boundaries.

Protecting Michigan's forests is a shared responsibility. Government agencies can establish safeguards, but residents and visitors must do their part by making informed choices. The new firewood quarantine offers a sensible opportunity to reduce preventable risks to the trees, landscapes and communities that make Michigan special.
