Survey finds ash borer has spread in N.H.


New Hampshire forest officials said a survey shows that an invasive beetle that destroys ash trees is present in at least 5 percent of the trees within an area of 24 square miles. The survey was led by the state Department of Resources and Economic Development’s Division of Forest and Lands to determine the extent of the infestation by the emerald ash borer. Foresters and volunteers collected samples from 195 sites within a 112-square-mile area surrounding the tree where the beetle was first discovered in March. The beetle was present in samples from 12 of those sites.
