Emerald Ash Borer
What is the Emerald Ash Borer?
Emerald Ash Borer (EAB) is an invasive insect that was first discovered in Detroit, Michigan in 2002. The insect has spread to Ohio, Indiana, Pennsylvania and Ontario, Canada. It attacks all varieties of ash trees. EAB has been found in 40 counties in Ohio, all of which are under quarantine to help prevent its spread. EAB has recently been found in, and is spreading throughout The City of Gahanna. Once infested, trees may show little sign of the pest for the first year or two. The larval stage of EAB feeds under the bark of trees, cutting off the flow of water and nutrients. They emerge as an adult the following year leaving a D-shaped exit hole. Adults are dark metallic green, ½” in length and 1/8” wide. The EAB flies from early May until September. Ash trees that become infested with EAB typically die within five years.

What is a Street Tree?
A street tree is defined as any tree located between the street’s curb and the sidewalk. This area is commonly referred to as the “tree lawn.”
Street trees are the responsibility of the property owner. Maintenance, planting and ultimately, removal of street trees are the property owner’s responsibility. Damage incurred by a street tree is the responsibility of the homeowner. It is important to maintain healthy street trees for safety, environmental and aesthetic purposes.
