Emerald Ash Borer Quarantine and Regulatory Information

The EAB is a serious invasive tree pest, and consequently a quarantine has been placed to help slow the spread of EAB to other areas in Minnesota (see Emerald Ash Borer Status in our state).

These are considered regulated articles by the MDA:

  • Ash logs
  • Ash tree waste
  • Ash chips and mulch
  • All firewood (non-coniferous)

No regulated articles are legally allowed to be moved into Minnesota without the written approval and the proper documentation provided to the Commissioner of Agriculture.

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 or contact the Arrest the Pest Hotline.
