EAB discovered in Wisconsin, a mile from Minnesota

The following information was sent out by the Minnesota Department of Agriculture (MDA) on April 7, 2009.

Emerald ash borer (EAB) has been discovered in Victory, Wisconsin. Victory is approximately 1 mile south of the Minnesota border along the Mississippi River.

This discovery was made only last week and confirmation was made on Monday, April 6. The Wisconsin Departments of Agriculture and Natural Resources have released the news of this find today, April 7. Although Wisconsin has not had much opportunity to evaluate the scale of this infestation, their initial assessment was that this was a significant infestation.

Due to the proximity of this infestation to Minnesota and Iowa, it is possible that the infestation extends into one or both states. The Minnesota Department of Agriculture, along with our partners at the Department of Natural Resources, USDA APHIS Plant Protection and Quarantine and USDA Forest Service are already investigating the southeastern portion of Houston County to determine if the infestation extends into Minnesota. We expect these initial surveys to last up to four weeks. If emerald ash borer is found in Minnesota, we will activate our EAB Response Plan (PDF).

Whether or not this initial round of survey discovers EAB in Minnesota, we will be intensifying survey and outreach efforts in southeastern Minnesota during 2009.

The complete press release that is being issued in Minnesota is here. Some key points to remember about the situation are:

  1. EAB has not yet been found in Minnesota, but state and federal authorities are investigating the area.
  2. No quarantines have been established in Minnesota. A federal quarantine will be imposed in Wisconsin on the infested area.
  3. At this time we are asking the public to voluntarily not move ash wood out of Houston County. A quarantine could be placed on Houston County by Minnesota Department of Agriculture in the coming weeks.
  4. For Minnesota beyond Houston County the situation has not changed. People should be vigilant as to the condition of their trees and report suspected infestations to MDA. Movement of untreated firewood over long distances should be avoided in any part of the state.

If you have questions, please direct them to MDA’s Arrest the Pest hotline.
