The adult emerald ash borer is a metallic green insect about one-half inch long and one-eighth inch wide making it hard to detect in the wild. The beetles lay eggs on the bark of ash trees which eventually hatch and bore through the bark to the fluid-conducting vessels underneath. The larvae feed and develop, cutting off the flow of nutrients and eventually killing the tree. EAB has killed hundreds of millions of ash trees since arriving in the United States in 2002, costing billions of dollars in removals, replacement plantings, and chemical treatments. This paper focuses on one of forty-three municipalities in New Jersey surveyed for frequency, diameter at breast height (DBH) and geographic location via GPS. It is expected that New Jersey’s experience with emerald ash borer will be no different from that of the other states that have seen this insect move through their communities. As such we can assume that, in the landscape, there is a high likelihood that all untreated ash trees will become infested and die. Previous studies suggest that 80% of the costs related to EAB will be borne by municipal governments and homeowners. The first confirmed identification of EAB in New Jersey was in May 2014 in Somerset County. Since then EAB has been confirmed in fourteen municipalities across six counties in NJ as of August 2015. An important consideration should be realized; all species of true ash trees (genus Fraxinus), which are one of our most commonly used shade trees in New Jersey, are threatened by the emerald ash borer.
