Heads Up - Emerald Ash Borer

The Emerald Ash Borer is a small green colored invasive wood boring beetle that attacks and kills Ash Trees. The Iowa Department of Natural Resources believes the Emerald Ash Borer may be up to 100% fatal to our native ash trees. The adults live on the outside of ash trees feeding on leaves in the summer months. The larvae feed on the living plant tissue just underneath the bark. The trees are killed by the tunneling activity of the larvae under the treeís bark.
The metallic green beetle is native to East Asia and was imported to the United States within the wood of shipping crates. The beetle was first discovered near Detroit in 2002 and has been found in Illinois, Indiana, Maryland, Missouri, Ohio, Pennsylvania, Virginia, West Virginia, Wisconsin and two Canadian provinces. Last year the Emerald Ash Borer was also discovered in Allamakee County in far northeast Iowa.
Research has shown that Emerald Ash Borer can only fly a few miles, but is easily transported on infested firewood, ash nursery stock and other ash items. It is this unpredictable transportation of the pest that is most concerning to area foresters. Left to its own means of travel the distance between Allamakee and the Polk or Dallas County portions of Clive, the Emerald Ash Borer may not arrive in this area for many years, but if it hops aboard a load of firewood or nursery stock, it could be here overnight and we could have an infestation within a couple of years.
City Staff are beginning to make plans to address possible concerns if the Emerald Ash Borer arrives in Clive. All city properties have been examined and at last count there are 779 Ash trees on publicly owned property. The City tree committee is meeting regularly to examine current city tree ordinances and to develop an Emerald Ash Borer plan to help the City be prepared in the event of an Emerald Ash Borer infestation.
