State environmental officials say the invasive, tree-killing emerald ash borer is spreading faster than anticipated in Berkshire County and now poses a greater threat to Eastern Massachusetts. Nearly 18 months after the Department of Conservation and Recreation first detected it in Dalton, the metallic green beetle has been discovered in several neighboring communities and in North Andover. Ken Gooch, the state’s Forest Health program supervisor, told The Berkshire Eagle that it is spreading faster than expected. The state quarantined Berkshire wood in a bid to limit the spread of the insects.
