  1. Emerald Ash Borer Introduction 2010 Minnesota Community Preparedness Workshops

  2. Emerald Ash Borer David Cappaert, Michigan State University

  3. Why is EAB Important? • Voracious pest with limited control options • Abundant host (Fraxinus spp.) with no known resistance • All ash species and sizes, regardless of state of health, are vulnerable to EAB

  5. Where is EAB?

  6. EAB Lifecycle David Cappaert, MSU

  7. How Does EAB Kill Trees?

  8. General Symptoms Canopy thinning Epicormic sprouting

  9. Suspicious Symptoms Woodpecker feeding Bark cracks

  10. Diagnostic Signs EAB Larva “S” shaped galleries

  11. ~1/8 inch wide Diagnostic Signs • D-shaped emergence holes • From adult EAB exiting from the tree

  12. EAB in Minnesota • Houston County • Found in Victory, WI – just across the border from MN • April, 2009 • Found on Federal Land in Houston County • April ,2010 • Ramsey and Hennepin Counties • Discovered in St. Paul • May, 2009 • Discovered in Falcon Heights (U of MN Campus) • November, 2009 • Discovered in Minneapolis • February, 2010

  13. EAB Known Infested Areas Minnesota map 4/30/10 Wisconsin Iowa

  14. What Can We Do About EAB? • Slow its rate of spread (mitigation) • Find it as early as possible (early detection) • Keep it from moving (prevention)

  15. EAB Mitigation

  16. EAB Mitigation David Cappaert, Michigan State University

  17. What Can We Do About EAB? • Slow its rate of spread (mitigation) • Find it as early as possible (early detection) • Keep it from moving (prevention)

  18. How is EAB detected? • Purple Traps • Tree Sampling

  19. How is EAB detected? • Visual Survey • Citizen Reports

  20. EAB Detection Surveys in Minnesota

  21. What Can We Do About EAB? • Slow its rate of spread (mitigation) • Find it as early as possible (early detection) • Keep it from moving (prevention)

  22. Quarantines and Wood Disposal

  23. Quarantines and Wood Disposal • Prohibits Movement of: • Ash material • Hardwoodfirewood • Ash debris must be disposed of or treated within the quarantine • There are no restrictions outside the quarantine boundaries.

  24. Why Respond and Prepare • Acting now = Spreading the costs over larger period of time • Provides a community with a reasonable and responsible method to respond • Opportunity to think about and coordinate sharing costs • Provides a community with a reasonable and responsible method to respond
