Emerald Ash Borer

Emerald Ash Borer is a shiny emerald green beetle, about 3/4" in length.  It feeds only on ash trees.  The eggs hatch in early summer and the larva tunnel into the tree.  Larva feed under the bark, consuming the cambium and phloem layers, causing the tree to die.  It was imported to Michigan from China in the 1990’s.  It was positively identified in 2002 as EAB.  In August of 2008 it was positively identified in the Village of Newburg, the first infestation identified in Wisconsin.  In June of 2010, EAB was found in the Downtown of West Bend.

Below, you will find some links to websites which contain more information about EAB and Ash trees.

Currently, the City of West Bend Forestry Department is working to remove all dead and infested ash trees.  There are still about 1,500 ash trees in the City that need to be removed, which will take many hours for our Parks staff.  In addition, replacing these trees will need require increased funding over the next few years.
