With money from the U.S. Forest Service, the Department of Conservation and Recreation surveyed the area by girdling — removing the bark from — more than 40 trees.
After the survey was completed, no trees were found to have emerald ash borer larvae except in the initial area of infestation off Route 125.
Plans for future surveys are being discussed and emerald ash borer traps will be used this summer across Massachusetts. Approximately 100 ash trees will be girdled in Essex County and will serve as trap trees to continue to help identify the extent of the infestation.
The warning signs of emerald ash borer include thinning of the upper canopy of the tree, increased woodpecker activity, early summer/fall leaf loss and D-shaped holes in the bark.
