The Emerald Ash Borer (Agrilus planipennis) is native to eastern Asia, first seen in the United States near Detroit in 2002. The Emerald Ash Borer (EAB) has no native predators and has spread throughout all of Ohio, and much of the eastern United States. The insect matures just beneath the bark of ash trees eating the vascular tissue of the tree, eventually leading to the tree’s death. All species of ash are affected, and the mortality nears 100%.
Urban Forestry has been removing ash trees throughout the city since the discovery of EAB in the area. Due to the extensive cost, and unguaranteed effectiveness of pesticide treatments, tree removal and replacement (with a non-ash species) is seen as the best long-term management option. Citizens are allowed the option of treating their ash street tree at their own expense after obtaining a signed Public Street Tree Work Permit from Urban Forestry.
