It has now been confirmed that the Emerald Ash Borer has been discovered in a privately owned Ash tree within the Winona city limits.
The EAB was earlier found in SE Minnesota in 2011 and its spread in the region had been anticipated.
City officials have confirmed the insect was found in the Valley Oaks subdivision.
Private property owners will be responsible for the removal of Ash trees that become infested and to dispose of them within Winona County. The County is under a state quarantine that prohibits untreated hardwood, including Ash tree firewood, from leaving Winona County.
A public disposal site will be made within the City of Winona for local residents. Contact Winona Public Works at 457-8269 for the location.
Removal and replacement, or ongoing chemical treatments are options for property owners to manage privately owned Ash trees. The spread of the EAB is anticipated to occur slowly for the next year or two and then to accelerate quickly thereafter. Prompt removal of infested trees may slow down the spread to other trees in the community and is encouraged.
