QTRA... V.T.A..... Or Lantra Pro tree inspection

[arb culture]

Bundle - Don't take this the wrong way, but have you ever read the book 'Living with Risk' which QTRA so often quotes?

 

I have a big suspicion that very few QTRA users have. I also suspect that very few QTRA users understand the maths which QTRA is based on.

 

For instance (and obviously just as a thought exercise): if you have 10,000 trees and each of them have at least a 1:10,000 chance of killing someone over the next year, what is the chance that at least one of them will kill someone over the next year?

Hamadryad - You need to do a course with some sort of nationally recognised assessment at the end of it to prove that you are actually competent to inspect and make recommendations about trees.

 

As far as I am aware the LANTRA PTI is the only short course available which meets this criteria, so that's the one you should do.

 

Good luck with it, whatever course you decide to take.

I did the PTI before I did the Tech cert, I found it useful and as others have said it does have an exam/competence element.

i know nothing of the book you are talking about, but i do like a little math quiz, i would say the answer is 1:10,000:001_smile:

No, not 1:10,000. The correct answer might surprise you though...

[Stephen Blair]

1 then

[arb culture]

Much closer.

 

Are you a QTRA licensed user?

[Tony Croft aka hamadryad]

If you have ten thousand trees, and there is a 1; 10,000 chance of somebody being killed then with ten thousand trees then I would say that one is going to kill aperson within the year?

 

which is utter utter rubbish of course, 2-3 people per annum (non arboricultural workers) your more likely to die from lightning than having a tree fall on you.
