Canterbury City Council have recently granted permission for the pollarding of three Willow trees on the banks of the Nailbourne at the southern edge of Bridge Recreation Ground where it meets Patrixbourne Road.
BridgeNature.org is not generally keen on the pollarding of ‘amenity’ trees: amenity in this sense means trees which are planted to enhance the appearance of a particular public space rather than for timber producing purposes. Pollarding is an ancient procedure which strips a tree entirely of its branches, thereby leaving just the trunk standing as a stump, which, if the work has been done correctly on the right type of tree and at the right time of year, will grow new branches over the next few years. In olden times whole stretches of woodland were pollarded to provide a regular supply of young branches for fuel or fencing. Riverbank Willows were often pollarded for flexible ‘withies’ for basket making, furniture and other products.
It is sometimes argued that pollarding rejuvenates a tree by encouraging new growth, but the suggestion remains controversial. Another more certain consequence of this method, if practiced regularly, is that the subject tree is restricted in height and span so that it takes up less space. For this reason the procedure is often adopted as a method of controlling trees in urban landscapes where space is limited; but the results can look brutal and unnatural to those who love trees.
All this begs the question, why pollard Willows on the banks of the Nailbourne in Bridge in 2017? We think this may be more to do with tradition rather than anything else, but there is a technical argument in favour too. Left to their own devices Willows will grow into very large trees which cast a lot of shade. They grow thick upper limbs, but the wood is weak and liable to crack and fall, particularly on the Crack Willow, which is how that tree gets its name. This is obviously potentially dangerous and unsightly on an amenity tree. As a measure to reduce such risks, Willows are often pollarded and these trees tend to accept the procedure better than most.
We have great faith in local tree surgeon Paul Davies, who will be supervising the work this year, as he did the same work to the same trees some 30 years ago. We understand the pollarding will be staggered so that all three Willows are not stripped at the same time. In his role as Parish Councilor, Paul Davies will also be overseeing shrub pruning and maintenance around Bridge Tennis Club, and he has already stated that he is keen to ensure work does not progress while wild birds’ nests are in use in the area. We thank him for this considered and responsible approach.
In the same location, beside today’s dry Nailbourne, the old bridge to the Recreation Ground is under consideration for replacement. We don’t know what sort of bridge will be installed, but in olden times a new bridge would have been constructed from local timber or stone, and some ancient peoples created bridges out of saplings which would be trained to form a living tree across the water. Ironically the best tree for this kind of project is… Willow.
