Mango tree with open cavity...

[Island Lescure]

Hi, yes it is in India. I know it was a bit of a long shot but I thought I would put it out anyway. I have done most of my tree work in this area but had not been back in 4 years. I think we might have even pruned this tree ages ago. Anyway, mango is a relatively strong tree in general, similar to ash but not as strong as oak. However, I wonder how fast the decay is occurring and if the tree can cope with the speed. Relatively fast growing.

 

Not many experts around here with regards to pruning, risk assessments etc... Fruit production is a different story, lots of experts on that.

 

Definitely more than one third sound wood when not accounting for the opening.

 

Anyway, they don't want to do anything until after the mango season is over, they are just starting to flower...

As noted the Bartlett/Mattheck formulae do not factor in wood strength, so they mislead. Trees are not pipes. As long as the woundwood around the cavity is intact, the tree is probably stronger than an undecayed specimen.

 

Mangoes are definitely tough; worked a lot on them in Florida and the Caribbean area.

So there is someone on here with a working knowledge of Mangoes....

 

But Guy, we want to think of them as pipes, creating simple formulas that decide fell or retain, that way we can deny all liability and don't have to give a considered opinion of wood strength, the relationship of the tree and fungal species, static and dynamic loads etc and that's before we even bring the value, aesthetic and environmental, of the tree compared with the risk of harm to the surrounding targets. (Tongue very firmly in cheek:biggrin:)

One's enough:001_tt2: when he has the right answer:lol:

Well I'm not sure it's right but I am sure we must heed the words in your sig line Mr. gaz!

 

Crazy degree of Data Envy in our 'soft science' of arb!

[Gary Prentice]

The following website has an online calculator that might help you: TreeCalc - Startseite (it does cost money to use it though).

 

Ps Gary you'll like this site. It's based on tree statics 😀

 

Sorry Paul I missed this.

 

Changes in circumstances has meant my studies have suffered terribly. I had a day out with the other Paul and got all the results emailed to me. I'm embarrassed to admit that I haven't looked at them:blushing:

 

It's an epic discipline to come to terms with and understand properly, although Paul went out of his way to explain, which I will eventually grasp. It's frustrating to life and work gets in the way of the learning:biggrin:

 

I will run through that program, when the opportunity arises, and compare against some of the other formula's out there.

There must be a tremendous reward for delving so deep into all that minutiae, with so little hope of learning anything useful about tree care.

 

Will 72 virgins be waiting when you hand it in?

[Gary Prentice]

All knowledge is usefull Guy, all knowledge.

 

If I don't understand how statics works, how the data is input and the accuracy (or not) of the figures used, how do I: a) interpret the results or b) make a judgement on the validity of them.

 

I understand exactly how fungal enzymes break down the bonds in the molecules that form cellulose. Do I need to know or just need to know that they do? Does that make me a better arboriculturalist, or not?

 

I'm sorry, but I simply can't support or disregard the discipline because that's what the rest of the herd does. I believe that it's simply ignorance to form a conclusion without a solid foundation to the decision. Speaking to a leading and very well known arboriculturist recently, who has no vested interest either way, his belief was that the lack of adoption or popularity in this country was simply due to the fact that people don't understand it.

 

At my age, 72 virgins offer little incentive to delve deeply into anything:blushing: knowledge and understanding bring me greater pleasure than the hedonistic activities of my youth:lol:

Thanks for the replies and advice. It will be inspected every 6 months. It will be interesting to see how it develops.

 

What studies are these BTGGAZ?
