Watch out for so called tree experts that do not understand tree biology.  [Ask them to briefly describe how bark forms, or better yet, ask the to "please explain five, only five, major anatomical differences between a woody root and a woody stem"?]  ANATOMY (parts) MUST PRECEDE PHYSIOLOGY (highly ordered movement of those parts) - ALWAYS!  I hear time and time again, "oh, its ok, go ahead its my tree" - sounds like the Garden of Eden - will the property owner defend you on judgment day? 
Beware of false prophets - e.g., if we cut the wood out the ecosystem (forest) will increase in health. FALSE this does not happen.  One, only one ref.  TELL THEM TO SHOW YOU THEIR DATA - THE PAGE AND PARAGRAPH WHERE WHAT THEY CLAIM IT SAYS IS LOCATED.  Take it from someone who spent many hours looking for something that was not there. http://www.fs.fed.us/pnw/publications/pnw_gtr164/
Storms, fires, floods, earthquakes, tornados, volcanic eruptions, explosions and other
abiotic forces keep reminding humans that they are not the boss.
Abiotic & Biotic switch places.

USA - Congress mandates and charges tax payers to log National Forests, with no DATA that suggest a future improvement to health of ecosystem, just impoverishments into future resulting from the lost functionality, the wood would have carried out, if it was not removed.
