These regulations for trees within conservation areas cover all trees and shrubs with a stem diameter of 75mm or more, measured at a height of 1.5m. This is regardless of whether the tree was planted or self-sown. Trees of this size will require an S211 application (known as an S211 Notice) which can take up to 6 weeks to process and allows the local planning authority a chance to assess whether the tree has amenity value worthy of giving it a Tree Preservation Order (often referred to by the abbreviation TPO).
Circumstances where an S211 Notice would not be required for trees above 75mm in a Conservation Area include dead and imminantly dangerous trees. Even in these cases, the council Tree Officer is required to give 5 working days notice (if possible) of any planned work so he/she can assess whether it is correct as an arborists assesment of imminanty dangerous often differs from a tree owners or other members of the public.
