Emerals Ash Borer damage in Houghton County

The Emerald Ash Borer beetle kills up to 99 % of the ash trees in any infected area. Michigan Tech researchers have been monitoring the damage done by the beetle north of the Portage Canal in Houghton County. But for the first time…the infection has been detected south of the bridge.

MTU will continue to monitor the progress of the beetle as work is done to try and put a stop to its spread. All of Houghton County is under quarantine…movement of any ash tree products is prohibited.
