Subject:  APHIS Adds Eight Counties in Wisconsin to the Emerald Ash Borer (Agrilus planipennis) Regulated Area


To:  State and Territory Agricultural Regulatory Officials


Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is adding Columbia, Door, Grant, Green, Iowa, Lafayette, Monroe, and Richland Counties in Wisconsin to the list of regulated areas for the emerald ash borer (EAB). APHIS is taking this action because of:


  • the detection of EAB in four of these counties,
  • the proximity of the additional counties to known EAB infestations, and also because of
  • known patterns of movement of regulated articles.


To prevent the spread of EAB to other states, the attached Federal Order outlines the conditions for the interstate movement of EAB-regulated articles from the quarantined areas in Wisconsin. Specifically, the interstate movement of EAB-host wood and wood products from the quarantined areas in Wisconsin is regulated, including firewood of all hardwood species, nursery stock, green lumber, waste, compost, and chips of ash species.


EAB is an invasive wood-boring beetle that is native to China and other areas of East Asia. The beetle is present in some portions of the United States, and because of its continuing spread, APHIS has established regulated areas that are designated in the Code of Federal Regulations (CFR) at 7 CFR 301.53-3 and the Federal Orders located at




The interstate movement of firewood from quarantine areas is an especially high-risk pathway for the spread of EAB. Therefore, APHIS works with state cooperators and foresters to prevent the human assisted movement of EAB, develop biological and other controls for EAB, and raise public awareness about this pest and the potential threats associated with the long-distance movement of firewood.


For more information about the EAB program and federal EAB regulations, please call EAB National Policy Manager Paul Chaloux at 301-851-2064.
