The Emerald Ash Borer has devastated tree populations in many Midwestern states, but a local wildlife expert says Iowa has been spared thus far. The Department of Natural Resources' Don Pfeifer says in order to keep it that way, people need to use local firewood. He says the borer lays eggs under the bark of Ash trees and can be transferred to along with firewood. Pfeifer says anyone who has guests coming to the area needs to remind them to get firewood here, and not bring it from places effected by the beetle.
