Familiarize yourself with the proper identification of ash trees and EAB. Learn more »
Monitor the health of local ash trees for dying branches at the top of the tree, known as crown dieback. Removal should be considered where damaged ash trees pose a risk to human safety or property. It is possible to treat ash trees that have not yet been infested. Contact local arborists for assistance with these determinations.
Transport of firewood remains a problem. Purchase firewood locally from a known source. Do not move any ash firewood or logs outside of a quarantined area. Be sure to use your firewood in the cold months so no EAB survive until spring.
Impact from EAB is now visibly apparent throughout the Chicago area. Tree removal is widespread due to damage from this forest pest. We recommend planting a variety of native tree species in place of ash trees that are removed in landscaped areas. Biodiversity, short for biological diversity, keeps our air and water clean, regulates our climate, and protects against devastating losses when invasive species, such as EAB, arrive in our local ecosystems.
