In 2002, a slender, shiny green beetle, the emerald ash borer, was found for the first time in this country in Michigan. Since then it has spread into the Northeast, Midwest, southern Canada, and some pockets in the South. In 2013, it was found in Granville County, and soon in Vance, Person, and recently Warren counties. North Carolina has four species of ash--white, green, pumpkin, and Carolina.Â Economically, white is the most important for it is used to make high-quality baseball bats. Pollock examines what is being done in the state to halt the spread.
