The City has over 1,260 ash trees. The Emerald Ash Borer (EAB) is a highly destructive, wood-boring insect that destroys ash trees. Without intervention, the City is at risk of losing a significant portion of its ash trees to EAB. Several years ago, a treatment plan was prepared and by following this plan, we anticipate close to 97% of our ash trees being treated.

The larvae stage causes the destructive damage to the ash tree.
