ST. PAUL — The Minnesota Department of Agriculture has confirmed an emerald ash borer infestation in Anoka County.

It says the destructive tree pest was found in an ash tree on private property in the city of Ham Lake.

The infested tree was detected through a call to the MDA’s Arrest the Pest Hotline, which allows concerned residents to report suspicious invasive plants and insects, like the emerald ash borer. Agency staff then confirmed the tree was infested.

Anoka County now will be put under an emergency quarantine and eventually join Dakota, Hennepin, , Ramsey, Houston, Olmsted and Winona counties in a state and federal quarantine. The quarantine is designed to limit the movement of any items that may be infested, including ash trees and limbs, as well as all hardwood firewood.
