Emerald Ash Borer

The Emerald Ash Borer larvae destroy the layer under the bark that transports nutrients and water throughout the tree. With this transportation system blocked, an otherwise healthy tree may die in 2 to 5 years. Therefore, EAB only attacks actual Ash trees.

Key attributes of ash trees include:

• Compound leaves with 5 to 9 leaflets
• Leaflets, buds and branches growing directly opposite from one another
• Diamond-shaped bark ridges on mature trees

Town staff estimate that about 16,500 Ash trees are infested with EAB in Fort Erie, with approximately 80% located on private property. Therefore, ash trees comprise about 60-75% of all trees in Fort Erie.

EAB-infested trees that do not receive treatment within a specific period will die. Unlike other tree species, Ash trees killed by EAB have complete tree failure sooner after death. As a result, infested trees are more likely to fall, increasing the risk of injury or property damage. The mortality rate of an EAB-infested tree can be as fast as one year, but it usually occurs within 2-3 years.

Town-owned EAB-infested trees are:

• Identified
• Tagged
• Marked with white paint by the Town Arborist

Trees marked with an "X" or "X&H" will be removed. Trees marked with a white "dot" identify the tree as healthy.

If you have an Ash tree on your property, contact a certified arborist to assess your tree's health. If your tree is healthy, insecticides are available that can protect it from an EAB infestation. If EAB has already infested your tree, a tree care professional can remove it before it becomes a hazard.

Don't hesitate to contact Fort Erie Town Hall at 905-871-1600 to speak with one of our customer service representatives. Customer service will add your concern to our list of trees to inspect.

• Refrain from moving infested wood material to new areas.
