Emerald Ash Borer
Emerald Ash Borer (EAB) was found in Concord in March 2013, and the list of towns with known infestations continues to grow. 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. Help protect New Hampshire's ash trees. A quarantine of all hardwood firewood, ash wood-products and all ash nursery stock is in effect for Belknap, Hillsborough, Merrimack, Rockingham and Strafford counties.
EAB has been detected in 54 towns in 7 counties in NH, most recently in Center Tuftonboro and Moultonborough in Carroll County and Bridgewater and Bristol in Grafton County. In response to the new conditions, cooperating agencies agree that the time is right to fully transition to a best management practices-based program. Agencies are seeking public comment on eliminating the within state quarantine from the EAB response. Provide your comments on eliminating the quarantine here.
