NH’s Emerald Ash Borer management recommendations continue despite federal regulation changes

The N.H. Division of Forests and Lands, in partnership with the N.H. Department of Agriculture, Markets and Food has announced that the state’s standards for transporting and using ash logs and firewood within New Hampshire remain in effect. This announcement comes on the heels of the end of federal ash quarantine regulations that were enacted to help combat the spread of Emerald Ash Borer.

Beginning Jan. 14, 2021, the U.S. Department of Agriculture will no longer regulate the interstate movement of emerald ash borer and will focus on supporting biological controls as its primary management tool for slowing the spread of EAB infestations. Previously, federal domestic quarantines had been in place that regulated the movement of ash products both within states and across state lines.

Although the federal EAB regulatory program is ending, some states will continue to regulate transportation of ash products into their state. Those transporting ash logs, firewood or ash products from New Hampshire to another state can check with individual states in advance to comply with local regulations, or contact the N.H. Division of Plant Industry for assistance.

It is important to note that this change in federal regulation does not change the best management practices already implemented in New Hampshire. These include:

  • Transporting ash logs only after Sept. 1 and having them processed by June 1
  • Shipping ash logs only to mills willing to debark them immediately
  • Confirming logs are likely not infested before transporting them
  • Moving ash firewood only if it has been heat treated to certification standards (140 degrees for 60 minutes)
  • Not transporting ash firewood more than five miles or seasoning it at its place of origin for at least 12 months
  • Delivering ash firewood after Sept. 1 and burning it by June 1

Limiting the transportation of potentially infested ash logs and firewood, combined with the cooperative program to combat EAB propagation through biological control, offers a two-pronged approach to managing statewide forest health.

EAB was first detected in Concord, N.H. in 2013; infestations have been found in all counties in the state except Coös. Once infested with EAB, ash trees die within three to five years.

A non-native insect, EAB lacks predators to keep it in check and ash trees lack resistance to the beetle attack. Long distance spread is primarily through the transportation of ash logs and firewood.

Ash trees are an important part of New Hampshire’s forest landscape and a valuable timber species of our forest products economy.
