11 Dateline Michigan Emerald ash borer strikes in Jackson County Dana DeFever, Staff Writer, Jackson Citizen-Patriot March 11, 2008 Thanks to the emerald ash borer the city of Jackson will lose about 300 ash trees by mid-april. The removal process, which started in December, is a little more than half-way finished with the 300 trees removal. More than 1,500 ash trees within the city right-ofway will have to be removed eventually because of the exotic beetle.

13 Detection

14

15 Survey Totals, ,723 visual tree surveys on 1,375 sites 1,167 trap trees on 457 sites 1,408 purple traps 2010 Survey Underway 1,700 visual tree surveys 412 trap trees 1,800+ purple traps

16 What should be happening BEFORE EAB is found? Need one ringleader. Inventory of resources ash, equipment, etc. Prioritize what you inventory first. How are you handling ash street trees now? (AKA Eat the elephant one bite at a time.)

17 What happens when found in DSM? Need one ringleader. Quarantines. Collection sites (marshalling yards). Financial assistance? Unlikely Pesticide applications Big money but big results? Biocontrol, maybe? Should be called bio-suppression

18 Erad vs. Contain vs. Do Nothing Eradication Delimit Quarantines! Eradication cuts? Suppression treatments? Hazard Trees! Govt $$??? Rigid Regulation Containment Delimit Quarantines! Hot spot cuts?? Suppression treatments? Hazard Trees! Govt $$??? Not as rigid, but movement out of Q-area is closely watched by IDALS & USDA Do Nothing Delimit???? Quarantines! Hazard Trees! Govt $$??? Not so rigid, but movement out of Q-area is closely watched by USDA
