V.T.A symptoms "the chatty trees"

[sean]

The tree's been listening to twist and shout...!

you're twisting my melon man..

[RobArb]

Do you think the tree is called Oliver?

spiral cracking?

anyway....ding ding....time out....

 

 

what the blinkin hells going on here then:confused1:

 

Glass is a liquid believe it or not, and incredibly thick liquid, if we think about trees the same way, which is a realistic thing to do not some crazy stuff! then it makes it a lot easier to comprehend.

 

Some say that helical growth is due to wind loads and optomisation, others due to genetics, I say its probably a bit of both but also the habit of plants to follow the sun as they grow.

 

for whatever reason this tree has grown in a helical pattern it is now also an old and decayed tree, tired and slumping a bit its wieght and form exagerating the tensions and compressions also increased by the selective delignifying decay a form of white rot that is typical of the ganodermas but I suspect in this case the white rot is that of inonotus cuticularis as this tree is a burnham beech and this site is rather special in both its languages and fungi colonisations.

 

so it is in effct like a barley twist stood on end and melting if thats easier to understand?

 

and very very cool.

just to re-iterate in simple terms (so its clear in my head), bud-proliferation FIRST due to virus, cankers and galls caused, fungi follows:biggrin

 

I am sure your right or rather your sources are, but I wasnt happy with "honestly" and factual claims without that conviction being explained!

 

what papers did you read recently rob?

Understood, knew you needed to see the evidence and not just me saying "honestly":lol:

 

Just trying to dig them out, i've saved them somewhere but got thousands of papers everywhere:blush:

 

 

From what i recall its something to do with the Cameraria ohridella not liking A. x carnea too:001_cool:

[RobArb]

There was something mentioned in this one but it won't open??

Re the Aesculus, have you considered Agrobacterium sp.? This can get in at failed grafts and cause cankers similar to what is pictured.

Re what to do about it; reduce 20-30% of the sprawl and install a cable, is one obvious approach.

Re the twisting beech, WOW.

Re the others, a lot of guesswork on the possible fungal origins of tree growth patterns, much of which may be accurate. But what to do about it? That seems to be the big question. Fungus may often win in the end and digest the whole tree, but in the interim...?

and theres our treeseer,

 

on the aesculus bacterium good pointer:thumbup1:

on the cable and reduction, no point field grown landscape tree, let it be, just there for the discussion, purpose fullfilled.

as for the beech, a site I am more than familiar with, sean never said it was a burnham beech did he! acurate? you have no idea:biggrin:

 

hows things

[treeseer]

Assuming that the owner values it in its current shape, and would mind terribly if it started to fall apart, then there is indeed a point to holding it together. Target rating is not just people property and activities. Trees have value, and are the first loss in any tree failure, and must be part of TRA calculations.

 

just there for the discussion, purpose fulfilled.

 

As was the cabling prescription. Assuming there is a point to holding the tree together, it would be a candidate for cabling, would it not?
