Brighton is the home of the National Collection of Elm Trees. We have, thanks to sea to the south and the virtually treeless Downs to the north, been better able to resist the depredations of Dutch Elm Disease. But sometimes just getting old is enough to settle your fate. One of my favourite elms, in front of the Royal Pavilion, has been seriously cut back. it did grow out at a startlingly low angle, and did threaten passing buses and lorries. And, yes I did walk under its mighty leaning bough swiftly. But its a shame to see so little of it now.
