The City of Owatonna is proactively treating approximately 400 boulevard ash trees for Emerald Ash Borer (EAB). EAB has NOT been identified in Owatonna, but has been identified in the City of Medford, resulting in a quarantine of Steele County. The effort by the City of Owatonna is expected to delay the spread of EAB. There are approximately 1,200 boulevard ash trees, and the City intends to treat approximately 1/3 each year, resulting in a three year treatment rotation. The treatment of the boulevard trees benefits private trees as well. When the bugs travel from tree to tree they die when they eat from treated tree. Not all trees need to be treated for the program to be effective.
