How can I get a Tree Preservation Order made on a tree that I think is at risk of being felled or damaged?
Your local council is responsible for making Tree Preservation Orders (TPO). You should contact your local authority and speak to the tree officer or someone in the planning department who should determine whether the making of a TPO is appropriate.
