If you are intending to undertake work on any tree within the Wrington Conservation Area you must normally give notice in writing to North Somerset Council and not start work without formal approval. The Council is consulted on these Conservation Area tree works applications, alongside applications for built development, generally commenting on the potential impacts on the tree’s public amenity value (its contribution to the local built and natural environment). If you weren’t aware of the full extent of the Conservation Area, this is shown on the plan which is available here.
Permission is required from the local authority for work on trees which are located within the Conservation Area with a trunk diameter of 7.5cm or more measured at 1.5 metres above the ground, or 10cm diameter if thinning is intended to assist the growth of other trees. The same rules apply to trees with Tree Protection Orders (TPO) wherever they are located.
There are certain exceptions such as when the tree is dead, dying or considered dangerous, or where the tree is directly in the way of development that is about to commence and for which relevant planning permission has been granted. However, you should always check with the planning authority before undertaking work.
It’s worth noting that if you fell, uproot or wilfully destroy a qualifying tree, or damage, top or lop a tree in a manner likely to destroy it then you could be fined up to £20,000. Also, you will normally be required to plant a replacement for any tree felled or removed without permission.
