The Mighty Angler: The emerald ash borer is native to Asia and is thought to have been introduced here by wood cargo transported in shipping cargo from China to the Great Lake area. It was first discovered in Michigan near Detroit in 2002. Since then it has reportedly killed over 5 million ash trees across the northeast. It is also now present in the southern border areas of Canada.
This species is spreading incredibly fast and considering that there are a variety of ash trees in most of the U.S. states; this invader could do massive destruction in the very near future. Once attacked by these beetles, the tree will usually be dead in three to five years.
