Can you put up explicitly where it's documented and proven that vegetation doesn't affect subsidence? In other words I'm looking for facts, we also have a thread on subsidence we could move these posts to.
I have been unable to prove what you are looking to prove. I draw your attention the extract below, this was given the weighting over the other guy.

By comparison, Dr Mitchell is a specialist on the latter, having obtained a doctorate degree which involved an examination of the magnitude of soil moisture loss from the effect of trees, published a book which, inter alia, examined the role played by trees in causing soil change around footings, and having also published many papers on this topic. Dr Mitchell was the recipient of a Churchill Fellowship to study cracking in houses, and a major contributor to the development of an Australian Standard for the design of footings on expansive soil. Dr Mitchell advised the Court that, since commencing private practice in 1974, he had examined some 8,000 cracked houses, at least 6,000 of which had been affected by nearby trees. |
