The emerald ash borer is a small insect doing a massive amount of damage. Tree experts say it will eventually kill nearly all of this country’s ash trees, and there’s not much that can be done to stop it. The devastation spread by the emerald ash borer is just one of many threats to the health and future of the nation’s trees and forests. Other kinds of insects, diseases, climate change and mismanaged fire areas are chief among the challenges. We discuss how our forests are changing and current efforts in forests and on city streets to secure the future of our trees.
