    The Emerald Ash Borer (EAB), Agrilus planipennis Fairmaire Coleoptera:Buprestidae), which is native to Asia, is a bright green beetle, no larger than a penny.

    First discovered in Michigan in 2002, it has since been responsible for the death and decline of millions of ash trees in the Midwestern United States.  If not controlled, it could potentially wipe out the ash tree species in North America.


    The Emerald Ash Borer was discovered in Carol Stream in November of 2007.  The Village has identified the location of all of the ash trees in the Village’s parkways. Trained staff arborists have recently completed an inspection of nearly every Ash tree in the parkway inventory.  As a result of the inspection, over 300 trees will have been removed before the end of 2011, and many more are expected to be removed in the coming years as decline continues.  At the same time, the Village is aggressively replacing parkway trees.  One-hundred fifty trees will be planted in November 2011.  Starting in Spring 2012 the Village will be planting several hundred trees per year for several years.


    While the Village does not have the resources to inspect trees on private property, a great deal of information is available for residents who may be concerned about the trees on their own property.  Symptoms of EAB infection are:  canopy dieback, trunk fissures, sprouting of new leaves from the base of the tree, and  D-shaped exit holes.
