EMERALD ASH BORER MAKES ITS WAY TO NORTH BARRINGTON

North Barrington, IL

First discovered in Michigan in 2002, the invasive wood boring Emerald Ash Borer has been confirmed in several Ash trees in North Barrington. Village officials are working on a management plan which will include surveying the Ash trees to determine the location of all Ash trees and the level of Emerald Ash Borer infestation. The village will then be able to weigh the cost of Ash tree removal versus control treatments for the Emerald Ash Borer.

An infested Ash tree may have a sparse canopy or dead branches in the canopy, D-shaped exit holes cause by the Emerald Ash Borer, or new sprouts growing on the lower trunk of the Ash tree. Woodpeckers feeding on the Emerald Ash Borer larvae will cause additional damage to the Ash tree by pulling off the tree bark, which can often be found under the infested Ash tree.

Ash tree treatments are available to control Emerald Ash Borer, if the damage to the Ash tree is not too far advanced.
Homeowners wishing to save their Ash tree should contact a local tree service to have an arborist inspect the tree. The arborist can determine if the damage is too severe or if Ash tree treatments are warranted.
 

ASH TREE REMOVAL TO START IN VERNON HILLS

Vernon Hills, IL

Village arborists are planning Ash tree removal for dozens of trees infested with Emerald Ash Borer. The green metallic beetle was first confirmed in Vernon Hills in August of 2010 by Illinois Department of Agriculture officials. Ash tree removal will be started on parkway trees and Ash trees on other village-owned properties. With approximately 30 percent of the parkway trees being Ash trees the makeup of the urban forest in Vernon Hills is going to change.

Symptoms of Emerald Ash Borer infestation include dead branches in the upper canopy of the Ash tree, thinning of the upper canopy of the tree, D-shaped exit holes on the trunk or branches of the Ash tree, increased woodpecker activity/damage in an Ash tree, vertical bark splitting, and new sprouts coming from the trunk or base of the Ash tree.

Vernon Hills Park District officials have been watching for signs of the Emerald Ash Borer, but no Ash trees have been confirmed to be infested yet. About 200 mature Ash trees in the parks have been treated with a trunk-injected insecticide in an attempt to ward off the Emerald Ash Borer.

Contact a local tree service if you want to have an arborist inspect an Ash tree on your property. A variety of Emerald Ash Borer control treatments are available. Emerald Ash Borer control treatments include tree spraying, insecticide soil injections, and tree trunk injections.
