SIA- the tree pulling test/theory

[Arctostaphylos uva-ursi]

One can only hope David.  So will the tree pulling be repeated on a regular basis?

I couldn't possibly comment, but there may have been someone keeping a watching brief from afar 

 

 

 

 

Ageist.

I bet my Viagra dealer is younger than yours.

I don't know tbh, but if and when the report becomes avaible and/or if the tree is subjected to further pull tests, I'll be sure to updated this thread.

I thought we both used Bullman ?

Back to the tests, how much force is actually exerted?

Is it ever enough to further damage an already compromised tree or root system?

Very little force loaded via the hand winch in reality, because the micrometers pick up on the smallest fraction/degree of tilt and the change in the length of the trunks peripheral wood fibres.

 

This method is thought to be non destructive and I understand that no tree has failed during an actual test.

I think I'm right in recalling that one tree (in the thousands that have been pull tested) has failed or had structural concerns after receiving a positive safety factor. (I'm not sure what the circumstances were with that tree)

Budget's a bit tight for the rest of the financial year so thought we'd give it a bit of a Heath Robinson affair !

Would a tree motion sensor of been a better idea to test the stability of the root plate?

Not sure if that's directed at me or the general membership, but I wouldn't know the answer to that Nick.

 

Have you experience with tree motion sensors for root plate stability?

 

Better = cheaper or better = more sensitive/accurate?

Thought half the lane was going to come up with at one point.
