Quite what motivated the vandalism is a mystery. There have been some justified concerns about the size of some of the trees on the estate, but these were many years off falling into that category.
I contacted the council’s tree section who confirmed that the cut was so low there was no potential for the trees to survive but that the sites, outside 99 and 109 Tyneham Road, are scheduled for replacement in the winter planting season later this year.
Unfortunately there are no witnesses at present, although the council are preparing a letter for nearby households to see if anyone has any information. If you did see something, please contact the council or, if you wish, feel free to contact me to pass on the information.
