Anoka County Under Quarantine for Emerald Ash Borer (EAB)
The Minnesota Department of Agriculture (MDA) confirmed an emerald ash borer (EAB) infestation in Anoka County on March 25, 2015. EAB was found in an ash tree in the city of Ham Lake.
Residents are encouraged to look at their ash trees for signs of EAB. Checking for EAB, reporting possible infestations, and following quarantines can slow the spread of EAB.
When checking for emerald ash borer look for the following:
- Be sure you’ve identified an ash tree. This is an important first step since EAB only feeds on ash trees.
- Look for woodpecker damage. Woodpeckers like EAB larvae and woodpecker holes may indicate the presence of EAB.
- Check for bark cracks. EAB larvae tunneling under the bark can cause the bark to split open, revealing the larval (S-shaped) tunnels underneath.
- Contact a professional. If you feel your ash tree may be infested with EAB, contact a tree care professional, your city forester, or the MDA at firstname.lastname@example.org or 888-545-6684.
Because of this find, Anoka County will be put under an emergency quarantine. The quarantine 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.The biggest risk of spreading EAB comes from people unknowingly moving firewood or other ash products harboring larvae. Below are three easy steps to keep EAB from spreading:
- 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.
- Watch your ash trees for infestation. If you think your ash tree is infested, go to www.mda.state.mn.us/eab and use the “Does my tree have Emerald Ash Borer guide?”
