Emerald Ash Borer (EAB) was found in Concord in March 2013. As a non-native insect, EAB lacks predators to keep it in check. Infested trees die within 3 to 5 years. EAB only attacks ash trees, and is responsible for the death of millions of ash trees in the midwest. Help protect New Hampshire's ash trees. 

A quarantine of all hardwood firewood, unprocessed ash wood-products and all ash nursery stock is in effect for Merrimack County.
