I can understand an unknowing homeowner making the serious blunders you mention here, but for hired services workers to do such is criminal. Another problem I see every year that makes my heart sick is the butchering of healthy, beautiful trees, in the name of professional pruning!
I have a young fireman's cap tree that I strapped 'cause it was wobbly. I always intended to remove the strap once it was firmly implanted, but the dang thang got embedded into my little tree way faster than I expected, in less than 1 yr. I was able to remove most of the strapping, but it deformed my trunk a little bit. Hopefully it will recover.
We could make a t.v. show similar to animal police for trees. My husband is a arborist who has seen everything as far as how trees can be abused. He is always trying to help people save their trees. I have seen him lose money refusing to do unnecessary and wrong cutting. Thanks for another good article. More awareness of property owners helps a lot.
