DECORAH, Iowa — The destructive emerald ash borer has been found in Winneshiek County.

The Iowa Department of Agriculture confirmed the pest on Friday.  An arborist was drawn to a tree in Decorah after seeing evidence of borer damage. S-shaped galleries and emerald ash borer larva were found underneath the bark of the infested tree.

The recent confirmation means the emerald ash borer has been found in nearly one-third of Iowa counties.

Winneshiek County is now part of the growing list of 31 counties that have confirmed infestations, the second of 2016.

The emerald ash borer is responsible for destroying tens of millions of ash trees.
