ASH BORER IN PLYMOUTH COUNTY
The Iowa Department of Natural Resources has confirmed that the presence of emerald ash borer has been confirmed in Plymouth County. An area tree service alerted the DNR of an ash tree in Remsen with symptoms of infestation. Emerald Ash Borer was first detected in North America in Michigan in 2002, and in Iowa in 2010. This Asian pest has now been detected in 36 states. Only two Iowa counties, Emmet and Palo Alto, have not had a confirmed case. The insect larvae tunnel beneath the bark of ash trees, cutting off the tree’s ability to transport water and nutrients. This damage typically kills an ash tree within two to four years.
