Don't Move Firewood

Protect trees, forests and wildlife habitat. Don't Move Firewood

Transporting firewood across state lines may inadvertently threaten Montana’s forests by introducing non-native invasive insects and diseases that could kill large swaths of native trees.  Tree-killing pests cannot travel far on their own but can easily hitch a ride on firewood.  These organisms travel without their typical array of parasites and predators. Free from these natural population controls, they can reproduce prolifically and swiftly displace native species.  Furthermore, many tree species have developed defenses against native insects and diseases, but have no defenses against an exotic pest.  The non-native pests can easily attack and kill otherwise healthy trees.  The effects can devastate forests, waterways, communities, agriculture, recreation and economies.

Even if local laws do not prohibit movement, it’s generally good practice not to transport firewood over long distances, particularly not across state lines.  Local sources of firewood are usually available and pose significantly less risk of transporting undesired insects.  If planning to transport firewood in or out of Montana, please consider the following:

  • Do not move firewood across state lines
  • Buy or cut local sources of firewood (within 10 miles of the place it will be burned)
  • If cutting off of public lands, keep the original permit as a mark of origin
  • Only move heat-treated or certified pest-free firewood
  • Do not assume that firewood is safe to transport even if it does not have any signs of infestation

Although not a guaranteed way to eliminate the spread of potential pests, the DNRC Forest Pest Management Program advises cutting firewood from trees that have been dead for at least three years, or curing firewood for three years before transporting. For more information, visit
