Bit of a moral hazard for planners here. Like the tram trees in Leith (which might now actually have been 'saved') the only reason the trees are there is because the area has been safeguarded for the purposes for which it's now going to be used. It would probably be Fountainbridge-style flats now otherwise. They are "temporary trees."
If your project is subject to an unexpected 10yr+ delay or your safeguarding lasts for many years (which is kind of the point of safeguarding) these temporary trees become quite big and folk get fond of them and object to them being cut down. But they were intended to be cut down from before they were planted!
The obviously worse but easier solution (which many property developers seem to already subscribe to) is to then coat all your safeguarded areas in glyosulphate every year and turn it into a toxic eyesore so objectionable that even the most obstinate residents are begging you to put your cycle route/playpark/student flats on it ASAP.
I admit that the article tugs at my heartstrings a bit, and it would be great if they can minimise felling, but we need to be mature about "temporary trees" in cities else they won't even get to be temporary.
Of course, this is really just another example of 'fighting over the scraps'. The WAR would make a fantastic habitat corridor with mixed native planting, sensitively placed paved direct walking/cycling routes throughout and little winding woodland walks. I'd go so far as to say it could become a world-class attraction, like the New York High Line. No expensive active travel bridges would need to be built and you could keep every single one of the trees on that map.
I'd be very happy to get on board with this campaign if that's the alternative.
