About Emerald Ash Borer (EAB)

EAB is an invasive insect from Asia. The larvae eat the wood under the ash tree’s bark, preventing the tree from moving water and nutrients between its roots and leaves -- killing it within two to four years. EAB has killed tens of millions of ash trees in North America since its discovery in 2002.

Emerald Ash Borer infestation has now reached several places Iowa. Within the year, urban forestry professionals expect to find more trees infested with EAB. Declining and dying trees may not be widespread for many years. If you have an ash tree, you should consider removal and replacement with a different tree or preventative treatment. We hope to connect residents with information so they can make informed decisions regarding ash trees on their property.
