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.

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.)


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‟
