Emerald Ash Borer Quarantine and Regulatory Information

The emerald ash borer (EAB) is a serious invasive tree pest, and consequently a quarantine has been placed on Anoka, Chisago, Dakota, Fillmore, Hennepin, Houston, Olmsted, Ramsey, Scott, Wabasha, Washington, and Winona Counties, and the island of Park Point within the City of Duluth, to help slow the spread of EAB to other areas (map). Materials such as:

  • Ash logs and lumber
  • Ash tree waste
  • Ash chips and mulch
  • All hardwood firewood;

These are now considered regulated articles by the Minnesota Department of Agriculture (MDA).

No regulated articles are legally allowed to move outside of a quarantine (untreated or treated), unless they are accompanied by a MDA certificate. MDA Certificates are only available when a Compliance Agreement (CA) is signed between the Minnesota Department of Agriculture and the a company, city, county, agency, or organization interested in moving the regulated article.

A CA is a written agreement between a person and a regulatory agency to achieve compliance with regulatory requirements. For more information about CAs please visit our Frequently Asked Questions (FAQ) or contact the Arrest the Pest Hotline.

Please refer to the official state quarantine for the full list of regulated articles and other important information regarding movement of regulated articles.

The EAB quarantine in Minnesota is part of a much broader quarantine effort by USDA enacted to slow the spread of EAB to states not currently infested with EAB (map).
