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.
