  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 • Ramsey and Hennepin Counties • Discovered in St. Paul in May, 2009 • Discovered in Minneapolis in February, 2010

  13. EAB Known Infested Areas

  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 • Visual Survey • Citizen Reports

  19. EAB Detection Surveys in Minnesota

  20. 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)

  21. Quarantines and Wood Disposal

  22. 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.
