It has been almost thirteen years since an invasive beetle revealed its metallic-green-shelled self to scientists outside Detroit. Since then, emerald ash borer (or EAB) has killed tens of millions of ash trees in Michigan alone and has moved on to 23 other states and two Canadian provinces.
Wisconsin isn't new to the list. EAB was first reported here back in August 1, 2008.
Over the years, WUWM has been checking in with scientists and foresters in our neck of the woods to learn how they deal with the threat of EAB.
