NY expands quarantine for Emerald Ash Borer

From the New York Department of Environmental Conservation

-- New York has added 16 counties to existing state quarantines that restrict the movement of ash trees, ash products and firewood from all wood species to limit the potential spread of the invasive Emerald Ash Borer (EAB).  The quarantines are in response to new EAB findings in the state.  
The Emerald Ash Borer has now been confirmed in seven counties in New York: Cattaraugus, Genesee, Greene, Livingston, Monroe, Steuben and Ulster. The expanded quarantine includes the counties where EAB has been confirmed and eleven others that are adjacent to confirmed detections both in New York, Pennsylvania and Canada, including Allegany, Chautauqua, Chemung, Erie, Niagara, Ontario, Orleans, Schuyler, Wayne, Wyoming and Yates.
The quarantines restrict the intrastate movement of the EAB insect itself, nursery ash, green lumber and any other ash tree material, including logs, stumps, roots and branches and wood products within and beyond, as well as into and through the quarantine areas. Because it is difficult to distinguish between species of firewood, all firewood and wood chips and bark mulch are covered by the quarantine.
The U.S. Department of Agriculture's Animal Plant Health Inspection Service (APHIS) is expected to issue a parallel quarantine for interstate movement in the near future.  State Agriculture and Markets' quarantine goes into effect immediately; DEC's quarantine goes into effect on the tenth day after being filed with the clerks of quarantined counties (approximately September 18).

EAB is a small but destructive beetle that infests and kills North American ash tree species, including green, white, black and blue ash. The first detection of EAB in New York was in the Town of Randolph, Cattaraugus County in June 2009. Subsequent infestations have been confirmed this summer in six other counties. In addition to New York, the beetle has also been found in Illinois, Indiana, Iowa, Kentucky, Maryland, Michigan, Minnesota, Missouri, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and Wisconsin.

New York has more than 900 million ash trees, representing about seven percent of all trees in the State. Ash is important in the manufacture of baseball bats and serves as a common shade tree in many communities.
Infestation in ash trees by adult beetles leaves distinctive D-shaped exit holes in the outer bark of the branches and the trunk. Other signs include tree canopy dieback, yellowing, extensive sprouting from the roots and trunk called epicormic shoots. Infested trees may also exhibit woodpecker damage from larvae extraction.  If it is suspected that an ash tree could be infested by EAB, go to for more information or call (866)322-4512.
