Emerald ash borer (EAB) has been positively identified in a residential tree in Newton in Jasper County from a larva sample collected on March 20. A citizen reported a suspect ash tree to city staff, who contacted the Iowa Department of Natural Resources’ forestry bureau to coordinate a sample collection.
EAB kills all ash tree species and is considered to be one of the most destructive tree pests in North America. Jasper County is the ninth Iowa county where EAB has been confirmed.
State officials will continue to track the movement of EAB. Before a county can be officially recognized as infested, an EAB must be collected and verified by USDA entomologists.
A statewide quarantine restricting the movement of hardwood firewood, ash logs, wood chips and ash tree nursery stock out of Iowa into non-quarantined areas of other states was issued on Feb. 4, 2014.
