The Emerald Ash Borer has killed millions of ash trees in the eastern part of the United States and portions of Canada.
A forester says they are keeping vigilant to slow the spread of the invasive insect to this region's national forests.

Emerald ash borer probably arrived in the United States on solid wood packing material carried in cargo ships or airplanes originating in its native Asia.
