I'm a registered forester in Michigan, Pat.

Ignore this "symplastless" guy... he's a wanna-be forester.
Lacking some serious formal education, and thus professional background.

Normally I do (in rec.gardens) but took a look at this thread.

(And as far as the symplastless fellow goes, I have no reason
myself to know exactly how bark forms, my dictionaries are on shelves
downstairs, and I don't 'feed' my trees or plants. I fertilize my lawn and,
as it's sometimes put, I 'feed' the soil' in my gardens with compost and
organic fertilizers.)

Myself and my colleagues have had to sort through the majority of his
posts on this forum.

I'm glad someone does it.

I do not believe that the American ash is "history", but there is no
doubt the bug has done some serious damage to many of our hardwood
stands in the central lower peninsula (or "810" area code as I call it -
even though the actual problem extends far beyond that area code's
boundaries).

I live in Osceola county (just South of Cadillac) and it has been found
in my county, but not doing damage to the extent that it did in lower
Michigan. I have not yet seen it in a stand up here. I hope it
continues that way.

I hope that that is the case...things look rather bleak from the middle
of 'ground zero.'

Locally, the initial symtoms of what was called at first (if I remember
correctly) 'ash decline' was noticed for several years before trees
started dying in vast numbers.

The biggest problem is vectoring. It cannot vector itself very far
(maybe a mile or two), but people can vector it very broad and very fast
via cars, hence the "moving firewood bugs me" campaign.

I actually had one (the first live beetle I'd seen) tucked under the
the windshield wiper on my car. I sure hope they don't normally
ride around that way.

Once it gets to a place where there are any form of ash trees, it goes
on a feeding frenzy that is like no other.

No doubt about that!

I've sold timber in Defiance County, Ohio - which was also one of the
EAB problem areas, but timber in NW Ohio is scattered enough as to not
be a problem for EABs.

EAB resistance is more than likely a futile attempt. The best way to
eliminate the problem is to eliminate the hosts where populations of EAB
are found. This critter is not known to prey on other trees.

Do you have much trouble getting property owners to eliminate
host trees? And in areas the EAB has run rampant over, can they survive
at a low level on the basal shoots that ash trees put out? I know that there
are many skeletal ash trees (especially along freeways* and in woodlots)
that are still standing and some still send up new shoots.

*I suppose the excuse for this is lack of funds...
