The tree just needs to be managed, the whole thing doesn't need to be cut down. I'm in London on a tree lined street, every year they come and cut branches. If trees are rotten then they are cut (we have a lot of non-native trees). In this bit of London there's a target to plant much more trees, so any cut down are replaced with a native tree. Property developers are a different matter, I'm pretty sure the huge tree behind the flat I used to live in was illegally cut down; if the council had been aware it would probably have had a tree protection order put on it.
