In the past ten years research has definitively shown firewood to be a major pathway for the long distance movement of forest pests across the United States. Here in NH the Division of Forests and Lands has conducted many surveys and research projects and found over 40% of the out-of-state campers were bringing firewood from home. Transporting firewood from California, New York, Florida and other distant locations was common. Out-of-State firewood the Division has confiscated and studied has averaged 35 insects per stick of wood. Additionally the breadth of species has been amazing. Species from the smallest flies to the largest longhorn beetles have been found in firewood.
Today all but five states have restrictions on the movement of out-of-state firewood or advocate limiting the movement. As of July, 2011 New Hampshire has banned the import of untreated firewood unless you meet the requirements for home or Industrial compliance agreements.
Those requirements include insuring the wood is from a designated green zone in Vermont or Maine, (see “NH Firewood quarantine zone map” link below), documenting the species, origin and destination, and ensuring the wood is at least a cord in volume and to be used for home heating or industrial use.
Homeowners who want to transport firewood from approved counties outside of New Hampshire can fill out and submit a Firewood Quarantine Homeowner Compliance Agreement by selecting the link on the navagation bar on the left. Be sure to click on the Quarantine Map below to ensure the origin of your wood is in a green zone.
Commercial operations transporting firewood from approved counties outside of New Hampshire should contact Kyle Lombard, Forest Health Program Coordinator, NH Division of Forests and Lands at 603-464-3016 or Piera Siegert, State Entomologist, NH Department of Agriculture at 271-2561 for a compliance agreement.
In addition an Emerald Ash Borer quarantine of all hardwood firewood is in effect for Belknap, Hillsborough, Merrimack, and Rockingham Counties. All untreated hardwood firewood cannot leave these counties without a compliance agreement.
