The emerald ash borer is a destructive beetle from Asia. It was first discovered in Michigan in 2002, but it is thought to have been present since the mid 1990's when it was introduced in ash wood used as shipping material. EAB was discovered in Randolph, NY in 2009 and has since been found in Alleghany, Chemung, Erie, Genesee, Greene, Livingston, Monroe, Niagara, Ontario, Orange, Orleans, Schuyler, Steuben, Ulster, Wayne, Wyoming, and Yates Counties. EAB will kill all ash trees left untreated. As of May 1, 2013 most of Onondaga County will be under quarantine to slow the spread of Emerald ash borer. That means that there are restrictions placed on the movement of wood products from quarantined areas into non-quarantined areas. All areas of the state south of the I-90 thruway and east to the state border, except for Rockland, Westchester, Nassau and Suffolk counties and New York City will be quarantined.
How to Identify the Emerald Ash Borer
Impacts of the Emerald Ash Borer
Emerald ash borer attacks all species of ash trees. Four species of ash can be found in Onondaga County, white ash (Fraxinus americana), green ash (Fraxinus pennsylvanica), black ash (Fraxinus nigra) and blue ash (Fraxinus quadrangulata). The mountain ash (Sorbus americana) is not a true ash and is not attacked by EAB. Ash makes up roughly 13% of forested trees in the County. New York state has the highest density of ash in the country. Ash is used for baseball bats, tool handles, firewood, and lumber. Black ash is used by Native Americans for basket weaving. Once an ash tree is infested by EAB, a tree may die within 2-4 years. A dead ash tree tends to break off in large pieces, and will be fall soon after it dies. The dead standing ash trees pose a significant hazard, and must be removed as soon as possible.
