Emerald Ash Borer
Emerald Ash Borer (EAB) was found in Concord in March 2013, in Canterbury and Loudon in spring 2014 and Salem and Hopkinton in the summer 2014. As a non-native insect, EAB lacks predators to keep it in check. EAB only 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 Merrimack and Rockingham Counties and the part of Hillsborough County east of the Everett Turnpike and the Route 293 loop around Manchester--including the highways. The parts of Hillsborough County added to the quarantine includes all or portions of the Hillsborough County towns of Pelham, Hudson, Nashua, Litchfield, Merrimack, Bedford, and Manchester.
