Emerald Ash Borer

Emerald Ash BorerThe Emerald Ash Borer (EAB) is an exotic beetle from Asia that was discovered in southeast Michigan and neighboring parts of Ontario, Canada, in July, 2002. EAB feeds primarily on ash and kills trees of various sizes and condition. Intensive surveys show EAB to be widely distributed in the Lower Peninsula of MI and into Ohio. Since its discovery, Federal and state officials have conducted surveys in Michigan and other high risk states, eradicated spot infestations detected outside the core infested area, initiated high priority research and technology development in support of survey and eradication activities, and implemented procedures to regulate the movement of infested ash material from the infested area. The Forest Service is working closely with USDA-APHIS and Canadian forest health specialists to develop integrated pest management strategies to best manage this pest in the US.

  • The emerald ash borer (EAB) is an invasive, non-native pest that has killed an estimated 8 to 10 million ash trees in southeast Michigan since it was first discovered in 2002.
  • EAB infestations were subsequently discovered in Ohio, Indiana, and Ontario, Canada. It continues to spread rapidly.
  • Spot infestations of EAB-infested nursery stock from Michigan were found in Maryland and Virginia. Early detection and treatment appears to have successfully eradicated the infestations in these two states.
  • In FY 2005 and FY 2006, S&PF funds were used to detect, delimit, and eradicate spot infestations in Michigan, Ohio, Indiana, Maryland and Virginia.
  • In FY 2007, funding will focus on detection, survey, and restoration activities in Michigan, Ohio, and Indiana, in partnership with APHIS and state agencies.
