4/17/19 - The Maine Department of Agriculture, Conservation and Forestry has announced a formal quarantine on emerald ash borer (EAB) and material that may harbor it.
Quarantine Area: The quarantine area includes all of York County and the northeastern corner of Aroostook County. The quarantine boundaries were drawn to include a buffer on those towns where EAB had been detected. EAB was found in northern Aroostook County in May 2018 and in western York County in September 2018. An emergency order has been in place to limit movement of infested ash from areas where the pest has been found since those discoveries.
The emerald ash borer (EAB), Agrilus planipennis, is one of the most serious invasive species threatening our ash resources and forests. All species of (Fraxinus) ash trees, but not (Sorbus) mountain ash, that grow in Maine are susceptible to injury and death by the emerald ash borer.
EAB was first found in Aroostook County. (Madawaska, Frenchville, and Grand Isle), and York County (Acton, Berwick, and Lebanon), ME in 2018.
