Emerald Ash Borer

Emerald Ash Borer (EAB) is a devastating insect pest of ash Fraxinus species, first discovered in the United States in 2002. Native to eastern Russia, northeast China, Mongolia, Taiwan, Japan, and Korea, it was accidentally imported into the U.S. through infested ash crating or pallets at least ten years ago. It is capable of killing numerous ash species including green ash Fraxinus pennsylvanica, a species used extensively in the central and western United States for windbreaks, shelterbelts, living snowfences, woody draw restoration, urban forests, native landscaping, xeriscapes, and other conservation plantings.

Emerald Ash Borer Quarantine to Be Expanded

February 5, 2013

New York State Department of Environmental Conservation (DEC) Commissioner Joe Martens and New York State Department of Agriculture and Markets (DAM) Commissioner Darrel J. Aubertine announced that the state will propose a revision to its Emerald ash borer (EAB) quarantine order to include all of the State south of the New York State Thruway, and east to the state border, except for Rockland, Westchester, Nassau and Suffolk counties and New York City.

All or parts of 22 counties are included in this expanded quarantine. The emergency rule expanding the quarantine will take effect May 1, 2013 and be followed by a permanent rule-making process. State and federal agriculture inspectors will be issuing new compliance agreements for facilities affected by this change. Read the full news release.

Emerald Ash Borer Confirmed in Orange County

New York State Department of Environmental Conservation (DEC) has announced the discovery of the Emerald Ash Borer (EAB) on the U.S. Military Academy at West Point campus in Orange County, New York. On July 13, 2011, a trap that was placed in an ash tree on the campus was found to contain an adult emerald ash borer. The USDA Animal and Plant Health Inspection Service (APHIS) has confirmed the discovery. The first occurrence of Emerald Ash Borer in New York State was confirmed by the New York Department of Agriculture and Markets and DEC on June 17, 2009 in Randolph, New York (Cattaraugus County).

Visit the NYSDEC Web site to learn the current status of the emerald ash borer. If you detect Emerald Ash Borers or damage caused by their presence, call your county Cooperative Extension, Regional NYSDEC office, or NYSDEC at 866-640-0652 or 518-402-9425.

Ash Seed Collection Initiative

In response to extensive tree mortality by the Emerald Ash Borer (EAB), more about the EAB, ash seeds are being collected for long term storage to preserve genetic resources of the ash species. This has been a combined effort of the Agricultural Research Service and the Forest Service along with NRCS, Bureau of Land Management (BLM), and over 50 cooperators. Visit the National Seed Laboratory web page to read more about the initiative and download informational materials.
