Is this a green ash?

I think it’s a green ash based on the bark.

Ash....but green and white are tough to tell apart. I start with site (if growing in a natural setting). Green are in wetter areas, white in dry. The way the bud sits in the leaf scar is different. The white ash bud is down in the leaf scar while green sits a little higher. The bark is VERY similar. Green ash bark is maybe a little more smooth/not as deep. More so on older trees. But in most cases...does it matter if its green or white?

I've always felt white ash bark could be sanded down with your hand. It's softer and smooths over easily.

I'm 99% sure that it's Green Ash

I was asked to look at the tree to see what I thought about its health. I was dumbfounded because there are about 10-12 mature ash and no EAB that I can detect. I’m trying to find an organization that can assist the owner in protecting this small grove. This isn’t a process in my wheelhouse since the only Ash I work on are dead.

In Toronto all the other species of ash were eaten first by EAB and the green ash were left to the end. Part of why mine lasted so long, years after the others were gone. Bit of imidacloprid helped after the basic it's still alive diagnosis. Also a bit of branches pointed up tree structure in green IIRC.

That's really interesting. Here in SE Wisconsin, with everything I came across, white ash were the last standing

I will confirm the statement.

Blue ash outlasts all others...it was never a common tree, but there are still big trees alive and well.

The Autumn Purple cultivar (of White ash) certainly held oon longer too - that played out in a few research studies. Don't know they ever figured out why.
