October means leaf-peeping, hunting and plenty of other fall fun.

It is also Firewood Month, a time to remember that moving firewood long distances can spread invasive forest pests hidden in or on the wood.

According to the Michigan Department of Natural Resources, untreated firewood is a known carrier of invasive tree pests and diseases. That harmless-looking stack of logs in the backyard may be harboring spongy moth or spotted lanternfly egg masses, oak wilt fungus or beech bark disease. These and other tree-killing invaders don’t move far on their own but can travel hundreds of miles on infested firewood that is transported from place to place.

Residents and visitors can still have a roaring campfire or a cozy night in front of the fireplace if you know how to burn safe. This advice comes from Michigan’s Invasive Species Program and The Nature Conservancy:

— Always leave backyard firewood at home, even if it looks fine.

— Buy firewood near where it will be burned — choose wood that was cut within 50 miles. Use FirewoodScout.org to find a firewood vendor near your destination. With more than 350 Michigan listings, you can comparison shop before you arrive.

— Certified, heat-treated firewood is safe to move long distances. Look for a federal stamp or seal on the package.

— If you buy firewood and don’t burn it all, don’t take leftover firewood home or to your next destination.

— Tell your friends not to bring wood with them; everyone needs to know they should not move firewood.

By choosing to purchase firewood at or near your destination, you avoid the risk of introducing harmful invasive species to the places you love. Your choice helps to protect the beautiful palette of fall colors and bountiful wildlife habitat that our forests provide.
