Trees in conservation areas

All trees in conservation areas are protected if they have a stem diameter of 75 millimetres measured at 1.5 metres from ground level.

In general, it is an offence for anyone to undertake work to a tree in a conservation area without giving us 6 weeks written prior notice. We use this to decide if the tree(s) should be protected from proposed work by a Tree Preservation Order (TPO).

Locations of trees in conservation areas

Tree Preservation Orders currently unavailable in Local View

Due to essential updates, details of Tree Preservation Orders in Local View and our internal systems are temporarily unavailable. We are unable to confirm whether a tree has a preservation order on it or not. We do suggest emailing our Applications Team at with your query before carrying out any tree work and we will respond as soon as we are able too. We apologise for any inconvenience.

Giving notice of tree works

To give notice of work to tree(s) in a conservation area complete the application for tree works on the Planning Portal website or write to us giving;

  • Details of the location of the trees to which the notice relates (by reference to a plan if necessary)
  • Details of the tree work operations being proposed 

You need to be clear about exactly what work you are planning. Vague proposals to "prune" or "cut back" are not adequate. You are advised to present a clear proposal and should consider discussing ideas with an arboriculturalist before submitting a notice.

It is helpful if you also provide:

  • Reason for the work, with reference to supporting evidence if necessary
  • Details of ownership of the trees

Give notice of tree works

It is not an offence to undertake work to a tree in a Conservation Area that is dead and dangerous. However, the burden of proof that work is exempt from the need for prior notice because of the condition of the tree(s) lies with the person carrying out the work. Anyone proposing to do work under this exemption is strongly advised to contact us for advice before hand.
