Interesting Biomechanics

4th pic is fantastic, as are the roots on the last ones anh idea as to cause?

 

Cute lil burls; resemble branch cankers i see on Q macrocarpa--perennial target cankers, unknown fungus involved; supposed to be Nectria per Shigo's guess.

 

down low where it is it could be that some kind of activity abrades them; mebbe not.

Tbh, I don't really know.

The area is lapsed coppiced 'oak'

 

Perhaps these are epicormics comming from the root that have been continually grazed

 

The area is also very wet, perhaps they are some kind of 'pnuemataphore' where the tree needs to aerate with its roots above the water.

 

Though i've only read/seen that phenomena on mangroves and swamp cypress.

I think this earlier part of the post got missed first time round due to some softcore thermoporn

 

 

 

 

 

 

Thoughts?

 

I would have to disagree with Tony who has obviously paid his dues with his undeniable grasp of scientific Arboricultural terminology.

I don't buy into the exaptation theory with regards to all crossing branches.

Especially not after my experience in a Sycamore yesterday.

We had been contracted in to crown reduce and install a cabling system in order to retain a tree with included bark at the base.

In my long journey around the crown I noticed on 3 occasions, examples where the tree had either successfully or was at the start of attempting to inosculate or naturally brace itself.

In every example I saw there was good reason to do so. Each occasion was an attempt to strengthen a weak feature. Two of the three were in order to prevent long term failure of limbs with included bark and once where a large scaffold limb had suffered from poorly thought out historical pruning leaving an unusual minor dog leg with lots of end weight.

I have seen it before, famously on the Redwoods of California where two enormous leading stems seem to be fused a regular intervals to give stability to obvious longevity.

I couldn't agree more with BatiArb's lucid comments on the removal of crossing branches without some longsightedness.

No disrespect to anyone who leans on Science to make their risk averse judgements in Arboriculture but isn't about time we open ourselves up to wisdom and common sense from time to time.

I will put my neck on the line and commit to my intuitive understanding that trees repeatedly display to me signs of intelligence with regard to inosculation.

I have experienced it my my own eyes.

I haven't yet proven it by the means of any form of tested data, that is all.

 

ps don't this type of discussion beat "my crane is bigger than your Unimog"?

Any images of your inteligent trees morningwood?

Nope but I'll endeavour to get some.

Do you disagree David?

Nice post and couldnt agree more, though not many would agree to tree or natures "inteligent design":thumbup1:

Do you disagree David?

 

Look forward to them

 

Don't disagree, my openness to natures ability to both work and mould its environment is what keeps my interest in trees beyond just work.

 

 

Have you read Cassian Humphreys' PDF on tree grafts?

Is that 'Self Optimisation of Gum trees – Braided Reaction Wood Development' because it doesn't seem to be out there anymore. Well, not to my limited IT ability to find.

Not that one, this one
