The Chequamegon-Nicolet National Forest (CNNF) has implemented firewood restrictions to slow the spread of emerald ash borer (EAB). This invasive beetle travels on firewood, so visitors are advised to leave firewood at home unless home is within 25 miles of the national forest destination.
The firewood restriction is one way of slowing the spread of EAB, an exotic beetle from Asia. The invasive insect’s larva kills ash trees by destroying the soft layer of wood under the bark. The risk of an EAB infestation in the National Forest within several years, even with quarantines and firewood restrictions, is very high.
Since 2002, EAB has spread to 19 states, including Wisconsin, and two Canadian provinces. Movement of infested wood or nursery stock from one location to another is the likely cause of new infestations beyond normal dispersal patterns of the insect.
Acceptable firewood to bring to the CNNF includes:
• Wood gathered from within the forest with a valid permit
• Firewood purchased from a vendor within 25 miles of the national forest destination or brought from home that same distance
• Wood that has been certified by the Wisconsin Department of Agriculture, Trade and Consumer Protection (certified wood may be brought into the forest from a distance of more than 25 miles)
In addition, state and federal laws forbid moving hardwood firewood as well as ash logs and nursery stock out of EAB-quarantined areas.
