The city of Winona is continuing its years-long work in slowing the spread of the emerald ash borer by cutting down and destroying some trees while treating others.

This year, a number of the trees treated in 2013 and 2014 — about 1,300 across the city — are up to be retreated as part of the three-year treatment cycle.

Winona public works director Keith Nelson said that city crews have been removing trees over the past several weeks along the lake trails, to reduce the risk of the sickly, brittle trees falling on the trail.

Other large groups of trees have been affected near Woodlawn Cemetery, but the ash borer’s presence in the city knows no boundaries.

“There’s hundreds of trees,” Nelson said. “It’s showing up all over town.”

The treatment, TREE-age, involves drilling a number of holes into an ash tree and pushing the chemical, mixed with water, up through the wood.

The city adopted a management plan adopted in 2012 as the ash borer was predicted to arrive in city limits. It was first discovered in Winona in April of 2014 but was likely present before then.
