Opinions please on large Beech

[mrtree]

What do you find odd Josbarb? That people are learning and applying knowledge about trees? Or a numerical represention is one method to discuss a portion of a complex problem? Or that some people can give an answer beyond I know and feel that that tree is not safe?

 

If anybody thinks it strange that formulas and percentages are applicable to trees they really should start to read on the subject of tree rick assessment. You will see that since the time of MAttheny and Clark's Tree Hazard Evaluation Form, through VTA, QTRA, Brian Kane's woork, SIA and SIM etc., many people have been tying to encourage a standardization of tree risk assessments that produce an answer that can be repeated by different individuals and is more than based on a feeling or some knowledge that cannot be expressed.

 

Of course the smart arborist will know that these formulas are not usable by those without some training and alot of knowledge. Just as we do not expect somebody off the street to do statistical analysis you cannot expect just anybody to do modern tree risk analysis.

Sorry, should have elaborated on the pics. If you imagine the stump in my pics to be a circle. The full bottom half or the circle, from the fungal bracket all the way round to the opposite buttress, had a crack in it it. The wind on that day was hitting the side of the tree from which the phots were taken with some magnitude. The whole thing lifted enough to enable you to place your fingers between ground and tree and then sat back. After monitoring this for an hour or so and contact from the local T/O, out came the 880. Crash bang wallop. (after a really quick climb up to attach a pulling rope).

Ok forget my 3% it was purely hypothetical, but you sir can not tell me that the tree will at no point be subjected to extreme winds.... Or infact any other force of nature...

Had the pleasure of working on this beech yesterday installing cabling,we reduced it 16 years ago .... before 87 /89 there was two thirds as many beech on this estate thousands went over so that is my opinion.... Storms happen and they do make trees fail, especially beech ..... Any how I would fell stevies tree on the grounds of summer branch drop and how prone beech are to it..... That's scare mongering.

Yes trees may be exposed to extreme winds over their life times. So MattF's response is that all trees are dangerous and should be removed. A massive storm, unlike any in that last couple of centuries means that all trees are now dangerous.

 

Oh and summer limb drop, remove all the beeches.

 

Not only is it fear mongering it is ignorance.

[MattyF]

No you are ignorant I never said that tree would fail but there is a very small chance that it could , common dazzle me with your matteck calculations and tell me there is no chance what so ever..... If the owners want the tree felled to make them feel safe it's there choice if they want to retain it and bask in all its glory that would be better but even if they wanted to carve it in to a giant phallus it's there choice... As for the summer branch drop comment you clearly have no sense of humour.

[mrtree]

What a waste even discussing this. The whole point of tree risk assessment is to understand the probablities, not what will happen only every couple hundred years. The storm of October 16 1987 was unlike anything seen in 250+ years. Since this seems to be what you base you risk assessment on then yes every tree will fail.

Steven your photos show a different story than we have been presented with earlier.

How do you mean? Do you think it is worse now i have done a cross section of the removed limb?

[mrtree]

No it is not worse, I believe that the large limb removal and associated decay was never mentioned previously. Now that we see the decay I think it gives some idea why some (non arborist) people may be worried. It helps to see what the factors creating the climate of fear amongst the owners are neighbours are.

 

Threads on forum never show the whole story. Often bits of information come out long after the initial post.

 

While we can use all the tree assessment knowledge available we must still look at factors other than the tree itself to inform our decisions about the tree's fate. For example it we have a big old tree next to a proposed (definite) building site, we may know that the tree will not collapse on the new building but the damage done to the roots may be such that the tree will decline over the years. The decision on the tree may be that it should be removed prior to building and new trees, suitable to the site, be installed. Thus the fate of the tree is based on something other than risk.

 

With your tree Stephen I can see why the owner may have decided to remove it and no amount of information would change that. Your decision then becomes do you want the work and publicity that comes with it or not.

[Stephen Blair]

2nd sentence in my first post, i mentioned the bracket and wound. My 3rd pic shows the where the limb was removed and there is a bracket under it but the picture is very poor.

[MattyF]

I don't think I have ever said I would or have used it to determain a risk assment of a tree and how dare you accuse me of doing so, I am mearly pointing out no one can guarantee it will not happen 100%
