Bad Grafts in Beech

[Marcus B-T]

Last week one of the threads mentioned some grafted Beech I'd looked at in North Yorkshire. I've put together a PDF so you can see what we found unfortunately we didn't get a core sample out to show you but we did get the Haglof corer stuck! It had nothing to grip on after about 10 cm. I've looked at a few Grafted Beech some are excelent some are pretty shocking.

 

Enjoy

V interesting case studies and well put together pdf Marcus.

 

Is this the case related to the Ustulina Beeches you mention on post 17 of Davids Beech Tree thread?

This isn't particularly related, but here's a Grafted Copper I've got.

Great Tree, low risk area, no work or further investigation required at this time.

Like your picture would also like to come and look at this tree with the old TI sometime. The trees I refere to in the pdf are not the Ustulina trees they are the ones refered to in thread 44 by Yorkshireman of Decay Detection Equipment. Can't believe I'm now quoting this stuff like references in a bibliography!!!!!

It's a cracker, ain't it?

 

You're welcome to come and have a look at this one anytime, if you're in the area give me a buzz.

Thanx for posting....

 

" This isn't particularly related, but here's a Grafted Copper I've got...."

I ve seen that one before....extraordinary beast....It so exactly illustrates the notion of Shigo's new tree/old tree....Would be interesting to learn of your findings Marcus...

Appologies for dragging up this old thread, but I went passed today and thought I'd share.

 

Here she is in all her glory

No apology needed here mate- thanks for getting it to my attention- really interesting to look at the pdf which i wouldnt have seen otherwise.

 

Your beech looks fantastic.

During recent inspection of two grafted copper beech, we decided to utilise the Resistograph to see if we could determine a change in wood density and structure across the grafting point.

 

Neither of the trees presented with any fungal fruit bodies to suggest that there was any degraded wood volumes within the outer radial section of the trunks.

 

Via the use of a sounding hammer there was a slight (but noticeable) acoustic difference in the wood below and above the grafts.

 

The following Resistographs were taken from below, above and through the graft of the second tree (pics 5, 6 & 7).

 

The reading from through the graft 'appears' to show a drop in drill resistance (@ 23 cm depth) roughly where we would expect the needle to have crossed the graft line.

 

........interesting, but we feel there is nothing of particular structural concern.

 

Funky fluting above the graft line though, eh

Great looking trees and work. Looks like the resi is reliable, and well worth the wounding if it settles all concerned without great loss of crown value.

 

How typical are failures of grafts like this?

I haven't seen a graft failure in 30 years, so would be interested to hear if anyone else has?

 

David Lonsdale has a section (2.1.2.4) in 'Principles of Tree Hazard Assessment and Management', that shows a failed Sorbus graft, and mentions that "grafts in trees have been occasionally been known to fail"

 

but that's all we've found (though not exhausted that particular search)
