Weird makings on oak!

[Caleb]

Felled this oak tree today and it has lots of little marks almost like bug boring holes.

Is this just the tree growing funny or is it something that we need to be worried about does anyone know?

Any help would be much appreciated thanks

Not sure were you mean . Is it on the cut face or on the bark .?  Marks on the bark might be were a fence was attached at some time ......

David H will know better but I think it is the results of tyloses with suberin forming in reaction to an injury, basically to compartmentalise the injury, maybe from a boring insect or a woodpecker going after it or even a Utility Arborist. It blocks the affected vessels  to prevent any infection travelling up or down.

So i think the 2 kind of match up like a bug or something has tried to boar into the tree. Its not from fencing as it starts at about 9m up on the tree.
It might not be anything but thought it looked a bit weird.
Thanks for your help

See pic, I reckon the bark has been exposed about 12 or 13 years ago, when the section between the two red arrows was the putside of the tree. At the blue arrow I think I see the next few growth rings curved in where the tree was beginning to occlude the wound. It had just finished healing over, a miracl;e of nature, then someone has gone and chopped it down.

 

The only thing that can really cause damage on a stem like that high up is another tree crashing against it. If that's what happened, it would have been a big impact and would probably have taken some branches with it, which could have caused cavitation and/or infection. I'd go with the tyloses idea, wiht phenolic substances created by the tree to make the dysfunctional vessels impenetrable to fungi.

 

A lot of supposition, but as good as I can think of.

Yes could well be as it is in a plantation that had a larch nurse crop that all got removed, highly likely that it got hit by one!
Thanks
