Quarantine Area in New Hampshire (a map)
Now we have a quarantine of all hardwood firewood, ash wood-products and all ash nursery stock for Belknap, Hillsborough, Merrimack, Rockingham, and Strafford counties. For the purposes of this quarantine firewood is defined as any hardwood less than 48 inches long. Though this quarantine area allows for the movement of firewood within it, using ash firewood as locally as possible is a voluntary method to minimize the spread of EAB within the quarantine area and beyond.
Humans move damaging insects far greater distances than insects move on their own. One of the most common means of movement is in firewood.
The State of New Hampshire implemented a firewood quarantine in 2011 to prevent the arrival of damaging insects by prohibiting uncertified firewood from entering the state.
