Tree survey and arboricultural report

A tree survey and arboricultural report is required for all developments that meet the following criteria:

Required where there are:

  1. Trees within or adjacent* to the application site that are subject to a Tree Preservation Order (TPO); or
  2. Where pruning works to facilitate the development are required on any tree within or adjacent* to the site that has a stem diameter greater than 75mm when measured at 1.5m above ground level; or
  3. Where any ground works (including works for services) will be undertaken within the canopy spread or a distance of 12 times the estimated stem diameter of any tree within or adjacent* to the site that has a stem diameter greater than 75mm when measured at 1.5m above ground level; or
  4. Trees within or adjacent* to the application site that form part of an ancient woodland**

The tree survey and arboricultural report must comply with British Standards Institute BS 5837:2012, include a tree protection plan and be prepared by a qualified arboriculturist.

* Adjacent means any tree that overhangs the application site or is within a distance of 12 times the estimated stem diameter. An additional distance of 15 metres is applied to ancient trees. 

** Ancient woodland is any wooded area that has been wooded continuously since at least 1600 AD (NPPG Annex 2: Glossary).
