Within a couple of months most of the tinny barriers were gone, whether through contact with bumpers or a particularly forceful gust of wind it's difficult to say, and some of the trees had even been knocked down. A jumble of litter bins, street signs and assorted bits of junk were drafted in as temporary protection.
Finally the tree pits are being remodelled with some kerbs around them. Hopefully new trees will also be planted to replace those that were lost. The tinny barriers are back but stand more chance of survival now that they are slightly elevated - not forgetting of course that many of Deptford's motorists regard kerbs and pavements as legitimate parking spaces, so don't hold your breath.
