Trees in conservation areas

When is a tree protected?

All trees with stem/trunk diameter of 7.5cm or more are protected in a conservation area.

Unless you are undertaking thinning work for the benefit of the growth of other trees in the area, in this case all trees with stem/trunk diameter of 10cm or more are protected. 

The diameter should be measured at 1.5m above ground level.

Should I notify the council?

You should not undertake work on protected trees within a conservation area in Lincoln without contacting us first. Even if a tree is dead or dangerous you should still get in touch with us first as we may prosecute if work is carried out without our consent.

You will need to complete an application form and send it back to us 6 weeks before you intend to carry out any work.

After your application and before any work can be undertaken an officer will make a site visit.  

Once the officer is happy that the tree does not require a Tree Preservation Order (TPO), and that the work is necessary, we will send you a letter to authorise your application.

If the tree requires a TPO you must not undertake any work without making a further application under the TPO legislation. 

Before you apply

Before you apply you may wish to contact someone who is trained and competent who can undertake the work. You will need to provide a detailed description of the tree and works that are being proposed, this might include:

  • Type of work, for example, tree removal, crown thinning, crown lifiting, crown reduction
  • Species and rough estimation of size of the tree
  • General condition of the tree
  • Any structural damage the tree is causing 
  • A sketch of the tree and any other related structures and trees

You do not have to be the owner of the tree to apply but you do need to have their agreement for any work to be undertaken and include their address in the application form.
