BOONE, Iowa — Another central Iowa county has been invaded by the emerald ash borer.
Two adult emerald ash borer beetles have been collected from a tap in a resident tree in Boone.
The resident suspect the beetle after a tree branch fell during a summer storm.
A statewide quarantine is in place restricting the movement of ash firewood.
The invasive species digs its way under the tree’s bark eventually killing the tree.
The ash borer has been found in twelve Iowa counties
