Trees in Conservation Areas

There are 40 Conservation Areas in Gwynedd (excluding Snowdonia National Park).

To see whether the tree you intend to carry out work on lies within a Conservation Area, go to:

You will also need to consider whether the tree is protected by a Tree Preservation Order.

Work on trees within a Conservation Area

It is an offence to carry out work on a tree (with a trunk diameter of more than 75mm (3") measured 1.5 metres (5") above natural ground level) which lies within a Conservation Area without providing at least 6 weeks notice.

This includes felling any tree or some of the tree’s branches, pruning, uprooting, etc.

You can submit a notice:

  • By post: Download the Application for tree works form (pdf) and return it to the address at the bottom of the application form itself.
  • Phone: 01766 771000 and request a copy of the form in paper format by post.

The Council will visit the site in order to assess the case. In some cases, a Tree Preservation Order will be placed on a tree.

Work on a dangerous / dead tree within a Conservation Area

If the tree is dead or dangerous, you must give at least 5 days notice (you won’t need to submit a formal application to fell the tree).

You can submit a notice:

  • Online: General enquiry about planning
    (you will need to create an account if you don't already have one) 
  • By post: Send a letter addressed to the Planning Service, Council Offices, Ffordd y Cob, Pwllheli, Gwynedd. LL53 5AA
