MONTPELIER, Vt.- Officials from the State of Vermont are reminding Vermonters in emerald ash borer (EAB)infested areasthat the beetles will soon be emerging from affected trees. Moving any infested material, especially ash firewood, logs, and pruning debris, can quickly spread the destructive insect. Optimal practices are to move ash from the infested area only during the “non-flight season” before EAB emerges. This, and other recommendations to slow the spread of EAB, are described atvtinvasives.org/eab.
These slow-the-spread recommendations have been modified for 2019, extending the “non-flight season” until June 1stto better reflect local conditions and insect biology. After careful consideration of EAB biology and Vermont weather records, the Department of Forests, Parks and Recreation and the Agency of Agriculture, Food and Markets have determined that EAB beetle emergence does not begin until June in Vermont.
EAB is an invasive insect from Asia. It was first discovered in Vermont in February 2018. The infested area now includes parts of Bennington, Caledonia, Chittenden, Franklin, Grand Isle, Orange, Washington, and Windham Counties.
EAB larvae kill ash trees by tunneling under the bark and interrupting the vascular system. Ash trees comprise approximately 5% of Vermont forests and are also a very common and important urban tree. Resources to help communities, landowners, and others plan for the impacts of EAB and the loss of ash trees, while maintaining healthy forests and public safety, are available at vtinvasives.org/eab.
