E.A.B. How far north

[moodnacreek]

How far north can eab go? I hope not as far as the ash grows. I was in an ash stand the other day; all dead, very sad and not safe to enter.

Your right, what a shame, all that strong handle wood, lumber and veneer .

In your area, it is total. Somebody needs to get in and cut that stand before it gets too far gone. Taking a lot of nice standing dead around here making good saw logs or nice firewood at least. Everything up here is either dead or dying. I am probably 40 miles north of you. The whole state is pretty much done.

We have it in a couple isolated areas in northern mn. The only thing that will slowit down is sustained frigid temperatures, as in lower than -35°F. I can't remember the numbers, but the longer the temp stays down in that area, the more of the bugs it kills, approaching 100%. We've had cold spells like that the last 2 winters, not this winter yet, though.

My wife's grandparents took great care of their place in Pompei NY near Syracuse.  Sadly her Papu passed a couple years back but we still visit the woods he managed and I've noticed a lot of variation in the Ash.  Some are dead but others seem unfazed, for now at least.  One of the last things he did was hire a youth group managed by a priest who salvaged the dying trees for firewood.  I've got my fingers crossed that there is a population of survivors.  They sure make a lot of seeds and could regenerate themselves a lot easier than oak or chestnut.

I hope you are right, but my observations have been that they take them all, even in a small area it takes a couple years for them all to die, but they do.  I have seen a couple try to re-sprout from the trunk but no good results yet.  I think this is our version of the Elm or the Chestnut.

In Ohio it is confirmed in every county.  The only species that I see survive is blue ash.  They can be completely healthy with green and white Ash falling apart all around them.  I suspect that they too will eventually succumb to EAB though.  They say there is a three year death curve where the trees can withstand infestation initially but by year three there is massive collapse within the stand.  Dan Herms from Ohio State University has published many papers on the subject and considered one of the leading experts if you find yourself wanting to research some articles.

I live 30 miles north of Montreal, Quebec and almost every ash in the city were cut down. Every city have a program to watch the trees and most of them are cut. I have a 60 acres wooden lot north of Montreal and up to now no signs of EAB.

When EAB hit in my son's floodplain forest in SE WI, he did attempt to "save" some nicer, still apparently healthy trees via injections of imidaclopyralid.  It only seemed to help temporarily, as in even before the expected 2-3 yr. protection period was over.  All other ash-these are green ash in this wet site-are dying or dead.  I would not expect much if any significant survival of any N. American ash species in affected areas.  it can look like it for a while, but I'd expect you're going to see all kinds of bark falling off, woodpecker holes, the whole bit.

I have heard reports on the border of Manatoba and Saskatchewan . Regina had replaced their elms with ash now they will need to find something else..

I found this 5 year old article regarding the mortality rate in the EAB under extreme cold. Perhaps it will give some folks hope, given the forecast for the coming 2 weeks. https://blogs.mprnews.org/updraft/2014/01/extreme-cold-may-wipe-out-high-percentage-emerald-ash-borer-larvae/?fbclid=IwAR2PxVjJTpUmiitc17xKQXMz5JJ4eji4J2cRjAS0SBEXp6IrYNw6utGjPEU

I think it reasonable to expect the EAB to ultimately colonize the entire range of Fraxinus in N. America.  Usually how it goes...though not absolutely.

This particular winter....in this particular area....may kill a few adults and overwintering instars.  It is very cold indeed.  Now.  But just before this....and most likely right after this cold snap.... we will be right back at above-average temps.  We may have had a few frozen out in the meantime.

I have yet to see any exotic invasive insect pest or pathogen not be able to get around to pretty much all the trees it is able to impact.
