Tree Preservation Order (T.P.O) Is where a tree is protected and covered by the local council. We know how to gain permission to carry out the work on protected tree's by applications to the local authorities. As a landowner there is a legal requirement to give notice (if applicable apply for consent), prior to any works being carried out on any tree's with TPO's. This protection does not mean that work cannot be carried out on your tree. It just means your application and reasons must be notified through the correct procedure which normally involves the tree being looked at by qualified individual that is appointed by the local council.
They will make recommendations based upon their assessment of the tree and the site, then the reports are submitted to the required planning authority who will either support or go against the application. The restrictions are in place to protect the benefit to the area where the tree is located.
