Help Protect New Hampshire's Forests With These Important Firewood Rules

With camping season in full swing for another year, most campers are aware that it is illegal to import untreated firewood into the state. So please leave that maple that you cut up in your backyard in Massachusetts or Connecticut!

But, according to the NH Department of Natural and Cultural Resources - Division of Forests and Lands, what you may not know, or forgotten, is that it is also illegal to transport hardwood firewood outside of Rockingham, Merrimack, Belknap, Strafford and Hillsborough counties due to the Emerald Ash Borer quarantine. Wood that has been certified as heat-treated to 160 degrees for 75 minutes is exempt from the quarantine.

A quarantine of all hardwood firewood, ash wood-products and all ash nursery stock is in effect for those five counties. For the purposes of this quarantine firewood is defined as any hardwood less than 48 inches long.

So that means the firewood you bought in Merrimack or Hillsborough counties can’t be transported to your camp or campsite in Carroll, Grafton, Coos, Sullivan or Cheshire counties.

Firewood is a major source of damaging insects and diseases and this quarantine helps protect the health of New Hampshire's forests.

In particular, the Emerald Ash Borer (EAB) was found in Concord in March 2013, and the list of towns with known infestations continues to grow to over ten towns at this point. As a non-native insect, EAB lacks predators to keep it in check. EAB attacks ash trees and infested trees die within 3 to 5 years.
