St. Paul takes on EAB

EAB Fight

"We are going to go into areas of the city where we find declining trees, remove them, remove the stumps, and replant," said city forestry technician Rachel Coyle. "That's just so that we're ahead of it; ahead of Emerald ash borer and ahead of the possible destruction and what could happen if there are thousands of dead trees standing."

Coyle is working on St. Paul's multi-pronged plan to deal with EAB. She calls this part of the campaign "structured removal."

These trees aren't necessarily infested with Emerald ash borer. They aren't even close to the St. Anthony Park neighborhood, where the flying pest was found six months ago.

In that neighborhood, most of the trees will stay to contain the infestation.



This strategy doesnt make complete sense to me. They are leaving ash trees in an area where there is a known infestation to contain the infestation. Wouldnt that just leave more breeding sites for EAB, and allow the population to grow? Maybe they are only leaving the "trap" trees and treated trees in the infestation area to contain the infestation?

So what other option is there? Remove all the ash trees so they beetles fly off looking for other ash trees in another neighborhood? Thus spreading more?

There have been some heavy restrictions put in place since EAB has been found. Transport of debris (brush, wood and even chips) is prohibited out of Hennepin and Ramsey counties. And just recently pruning and removal is not to be carried out between roughly March and September ( i dont recall the exact dates).

EAB has taken a foothold in my area of the state of Ohio. Initially, the insects were detected in landscape trees transported from an infested area to the area where I live.
Initially, an eradication program funded by the Federal Department of Agriculture had every Ash tree over roughly 1 inch diameter, from what I do remember, removed within a specified distance, for which I don't remember, from the discovered initial infestation.

Once this eradication program was complete, we (people in my area) were temporarily relieved the insect was gone. It was again discovered by a local "I.S.A. certified arborist". Again, this discovery made the local news. The money provided by the federal government to remove trees ran out. Now, the Dept. of Agriculture's support is with free information to pass out to clients who have ash trees.

I have been informed by my local extension office when finding an infestation; tell the people to remove the trees, or treat the trees with chemicals. No seasonal restrictions have been mentioned about pruning or removal. In our state, our people tell us to remove the trees upon discovery of EAB to avoid spreading the infestation. Unfortunately, it needs to be done at the homeowners expense.

It has been 2-4 years since I first heard of EAB here. I discovered EAB for the 1st time this last spring 2009. I suspected EAB when I had seen many borer type holes near older topping wounds on an Ash tree I was pruning. I'm better informed about EAB now and better at detecting it. I found information about the EAB through federal publications and local I.S.A. seminars.

If one questions a newspaper artical or the philosophy behind their public officials, simply ask them. They want questions and can use you to spread their philosophy to others.

There are webinars being offered to help people learn about EAB at the above address. Previous webinars have been recorded.

Has any1 found out the logic behind the management strategies with the Ash trees?

B.T.W., the webinars through the eab website are worth watching if some1 is interested in learning about eab.
