The Minnesota Department of Agriculture recently confirmed an emerald ash borer infestation on property on County Road 17, just 600 feet from the border of recently-annexed city of Winona land. Two trained borer spotters located the infestation, including property owner and retired Winona State University professor Carol Jefferson. Jefferson said she believed the infestation was present last year, but the insects were too high up in the trees to inspect.
The emerald ash borer is a highly destructive invasive species that kills ash trees. It was first spotted in the Twin Cities in 2009, and has since been located in Ramsey, Hennepin, Houston, and Winona counties. All affected counties have been quarantined, meaning firewood products may not be transported outside of an affected county.
