    This fairly terrifying video:

    made me wonder whether there's another good reason to properly provide space on pavements and take away space from cars. It just appears from that the planted trees near roads have had no chance to grow a proper root system - but I know nothing about it...

    My dad used to do consultancy for Aberdeen City and did have to point out to incredulous officers that trees a) have a life span and b) get sick and die.

    When a tree gets fungal root infection it sometimes throws all remaining resources into leaf, flower and fruit as a last hurrah. Such trees catch summer wind storms and fall over.

    ah ta for that - so this is a red herring and I should remove it from my arsenal of moans?

    I had always assumed that trees would have deep roots - perhaps as deep as a tree is high, but they mostly go sideways.

    Presumably they won’t go far if there is no water to be found under roads, pavements or paved front gardens?

    Depends on the species. Oak and walnut have huge taproots, birch are surface-skimmers.

    There's some interesting video of a big tree at Drylaw police station rocking in the May winds this year. Had to be brought down before it fell down.
