Thank you the Chinese. I watched all the ashes in Michigan die in the middle '00s. The biologist sleuths traced it back to contaminated crate wood that arrived in Detroit from China. "Certified pest-free", of course, but that means nothing to the Chinese.
There was a short time when kiln-dried ash could be had for next to nothing, but soon the sawmills wouldn't buy ash at all, because they couldn't sell it at a profit, so it was simply burned in tremendous bonfires.
Mature ashes are all dead in the woods here
Same with hemlock, elms
And I kill the Norway maples
Younger elm and Ash doing fine. Takes a number of years before they’re infested
