@zoowar in the #sheffield case the management and maintenance of the roads has been outsourced to a private multinational - Amey. They declare the trees "antisocial" and "discriminatory" and remove them to repair the roads. One of the issues is that other methods can be used to both preserve the trees and fix the roads, but when this has been pointed out, from recourse to the Councils own "Independent Tree Panel" it's been ignored.
