Identifying an Emerald Ash Borer
An infestation of this non-native beetle has been confirmed in neighboring Fairfax County. The Emerald Ash Borer was 1st discovered killing ash trees in Michigan in the late 1990s.
Accidentally introduced into North America from Asia, the Emerald Ash Borer has killed tens of millions of ash trees and caused billions of dollars of damage to the forestry industry. This is only the 2nd time that this pest has been found in the Northern Virginia area since a minor outbreak was contained in 2003.
Types of Ash Trees
There are many
species of ash trees and the emerald ash borer will attack them all; the
result is almost always fatal. Green and White Ash trees are commonly
found in this area. Please visit the Dendrology at Virginia Tech Web
site for more information on how to identify ash trees.
Signs of Infestation
Early detection is the best strategy for management of the pest. Signs of emerald ash borer activity include dieback in the top 3rd of the tree canopy, sprouts growing from roots and trunk, bark splitting and D-shaped exit holes. To learn more about emerald ash borer please visit the United States Department of Agriculture (USDA) Forest Service website.
The emerald ash borer does not generally spread great distances on its own. It is mainly spread when various ash articles (firewood, wood chips, nursery stock, etc.) are transported from infested areas to uninfected areas.
Residents are asked to report any signs of declining or dying ash trees by contacting the Department of Public Works at 703-248-5350 (TTY 711) or firstname.lastname@example.org.
