Tree management and preservation orders
Trees are protected if they are in a conservation area, or if they are the subject of a tree preservation order (TPO).
This prevents cutting down, uprooting, topping, lopping, wilful damage or destruction of trees and roots without our permission.
Tree preservation order regulations have changed; previous legislation has been brought together with a new act that took effect from 6 April 2012.
