In conservation areas notice is required for works to trees that have a trunk diameter of more than 75mm when measured at 1.5m from ground level (or more than 100mm if reducing the number of trees to benefit the growth of other trees).

We need six weeks notice before carrying out work on trees which are located in a conservation area but are not yet the subject of a tree preservation order. This gives us an opportunity to consider whether an order should be made to protect the trees.

Applicants will normally need to contact us before any work can be carried out on protected trees and may wish to discuss your needs with a arborist or tree surgeon before contacting us.

When applying specific details regarding the works to the tree(s) must be provided. Where necessary we can refer a vague or ambiguous application back to applicants and ask for clarification. Any necessary minor clarification should be confirmed in writing by the applicant either in a separate letter or by modifying the original application. For significant changes that alter the nature of a proposal, for example where consent is sought for felling instead of pruning, the applicant should withdraw the original application and submit a new one, including these documents

• application form and ownership certificates
• a plan that clearly identifies the tree or trees to which the notification applies to and any other surrounding properties that may be affected by the works to the trees

Further information about this type of application is available on the Planning Portal.
