The Minnesota Department of Agriculture (MDA) confirmed an emerald ash borer (EAB) infestation in Dakota County. EAB was found in an ash tree in Lebanon Hills Regional Park in the city of Eagan, just north of the border with Apple Valley. The infested tree was detected through a routine visual survey of ash trees currently being conducted by the MDA. This survey is designed to find EAB in counties bordering the Ramsey and Hennepin County quarantine area.

Dakota County becomes the sixth county in Minnesota to confirm EAB. Additionally, EAB has also been found in Hennepin, Ramsey, Houston, Winona, and Olmsted (which was just confirmed this August) counties. These counties all have a state and federal quarantine established. The quarantine is in place to help prevent EAB from spreading outside a known infested area. It is designed to limit the movement of any items that may be infested with EAB, including ash trees and ash tree limbs, as well as all hardwood firewood.

This is especially important for Minnesota as there are approximately one billion ash trees present in this state. And all are susceptible to this invasive beetle. It is critical that people be aware of and follow the quarantine to minimize the spread of EAB. The biggest risk of spreading EAB comes from people unknowingly moving firewood or other ash products harboring larvae.

Every Minnesotan can help prevent EAB from spreading by taking the following steps:

• Don't transport firewood. Buy firewood locally from approved vendors, and burn it where you buy it;

• Be aware of the quarantine restrictions. If you live in a quarantined county, be aware of the restrictions on movement of products such as ash trees, wood chips, and firewood.

• If you think you have seen an infested ash tree, go to www.mda.state.mn.us and use the "Do I Have Emerald Ash Borer?" checklist or contact MDA's Arrest the Pest Hotline by calling 888-545-6684 or emailing Arrest.The.Pest@state.mn.us to report your concerns.
