Thank you Jerry and Rupert. I had thought about the angle grinder as this 
would seem to be a cheap and easy solution that just might work.
I think it may get some odd looks but hey will keep you posted of the results 
in due course.

Any other suggestions? Or have others tried the bridge grafting or similar 
remedial work as above.

Hi Ian ,
Nice to hear your (digital)voice again.
Re the Gleditsia, is there any way you can get an angle grinder in and cut 
the collar in 2 or 3 places; allowing little bridges of cambium to keep the 
trees alive until they callus over the ring and start proper vascular 
conduction again?
PS you might like this photo from a stately home near Exeter; the tree is 
surviving....planted 1859..
All the best

Rupert

Hi Guys,

It has been a few years since I last posted and hope all are well.

We have an interesting case regarding Gleditsia triacanthos which I would 
like to share with the collective.

Several trees of the above where planted approximately 30 years old in a 
precinct, these have grown within cast iron grates and steel cages.
They have enveloped the collar at the steel cage base. The cage has been cut 
away leaving the lower steel brace at the tree base.
The tree has reacted to this by Contact Stress Response. It cannot be removed.

Question: will the tree survive the girdling caused by the collar, or will it 
fail?

Picture below of same tree before we became involved and cage removed.
