Emerald Ash Borer Found in Iowa

Emerald Ash Borer

Well.  It’s confirmed.  The Emerald Ash Borer is in Iowa.  It was found in Allamakee county along the Mississippi River two miles south of the Minnesota border on property owned and managed by the U.S. Army Corps of Engineers and the U.S. Fish and Wildlife Service.  It doesn’t sound like much, but four larvae were found in one ash tree on the land and that is bad news. An infestation was discovered last year in Victory, Wisconsin which is nearby.

If you don’t know if you have an ash tree, I found this link to help you identify them.  It’s from Michigan State University.  Michigan has had the infestation since 2003 and has lost millions of trees.  Iowa could lose 80 million.  about 50 million in rural areas and 30 million in urban sites.

Here is a site about the Emerald Ash Borer with more information.  It includes the fact that Michigan has lost tens of millions of ash trees and tens of millions more have been killed in Illinois, Minnesota, Indiana, Kentucky, Pennsylvania and several other states. 

I previously talked about the EAB.  You can check out that page here.  In that post I mention that the species Fraxinus is the one that the EAB likes to munch on.  I have a Purple Mountain Ash which is of the Sorbus species and not a true ash, so I don’t think the critters will affect them. 

I will post more about the EAB as it comes along.

Dig it!

    You mentioned on this mornings news that the EAB causes the D shaped holes by entering the tree. They cause it by exiting the tree. Also the Mountain Ash isn’t a true Ash. There are many trees, depending on the state you live in that have trees they refer to as Mountain Ash. I think you have given a false hope that there are true ash that are not affected. This information is from ISU. I have been following the EAB reports for the last three years. And have attended classes at ISU on the subject.
