progressive bark loss

[oakashalder]

As mentioned in the "sycamore dieback" thread, I am seeing this problem on members of the maple family, mostly: field maple, norway maple and sycamore. There is one occurence on ash, though, as in the attached image, and I'm looking nervously at some bark cracking on some alder.

The images "on field maple_2" and "on sycamore" show the narrow ribboning of the peeling outer bark.

Has anyone else seen this or know anything about it? I looked at images of sooty bark and they don't match this.

squirrel damage trying to heal over on middle pic, lower trunk damage, sheep grazing on the bark, happens alot on poor grazing and sometimes they just get a taste for it, will heel over, but remove stock or fence

We have alot of the same damage on a site we work and it's our little grey furry friends running around the trees they love to eat.
