The emerald ash borer (EAB), Agrilus planipennis, was first detected in Maine in 2018, following its discovery across the border in New Brunswick. It is one of the most serious invasive species threatening our 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. Trees injured by EAB become brittle and threaten the safety of property and persons around them. Property owners, municipalities, and others are encouraged to learn more about their trees and whether EAB is a concern.

To slow the spread of the destructive emerald ash borer, we encourage everyone to follow regulations and best management practices when handling ash within regulated (quarantined) areas.
