Emerald ash borer (EAB) is an invasive insect that threatens to destroy North American ash trees following its accidental introduction from Asia in the 1990s. Since then, efforts have been underway to identify the most effective means of protecting ash trees from attack.  

In recent years, EAB has become a significant threat to urban and community forests throughout the nation as it kills both stressed and healthy ash trees that not only beautify neighborhoods but provide shade to cool streets and homes. Loss of these trees has a staggering economic impact on communities that must  spend thousands of dollars to manage or remove infested trees and replace with other species.  

On Arbor Day, learn how scientists and Extension staff at Land-grant Universities are helping their communities and states manage this invasive pest with funding from USDA’s National Institute of Food and Agriculture.
