Firewood Movement in Wisconsin

Two quarantines exist in Wisconsin that affect firewood movement for the general public: A gypsy moth quarantine and a quarantine for emerald ash borer. Please note that loggers, timber haulers, and sawmills are already regulated and are not a concern. The inspections and certifications they require in order to transport hardwood firewood ARE NOT available to the general public.
