Quick Fact Sheets
Emerald ash borer (EAB) and other damaging insects move far greater distance by human-assisted transport than the insects move on their own. One of the most common paths of movement is in firewood. Ten years ago, we never would have guessed that firewood would spread the most destructive non-native pest in the northeast forests, but here we are today with emerald ash borer in over 10 towns.
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. Read about this out-of-state firewood quarantine.
Now we have a quarantine of all hardwood firewood, ash wood-products and all ash nursery stock for Belknap, Hillsborough, Merrimack and Rockingham counties. For the purposes of this quarantine firewood is defined as any hardwood less than 48 inches long.
