Tree Survey or Arboricultural Assessment

How to prepare a tree survey or Arboricultural Impact Assessment and Method Statement

What the survey and statement should include

There is a formal British Standard which covers how to prepare a tree survey or Arboricultural Impact Assessment and Method Statement (British Standard 5837, 2012).

The requirements are slightly different for Full planning applications and Householder applications, as follows:

Full planning applications

  • An arboricultural impact assessment and tree retention/removal plan
  • Any pre-development tree surgery works
  • Arboricultural method statement (heads of terms) with indicative tree protection plan of retained trees
  • Existing and proposed finished levels; proposed location of underground services any special
  • Engineering or other relevant construction details within the root protection areas
  • Soft landscape design. Including species and location of compensatory planting to mitigate for any removed trees
  • The tree survey, arboricultural impact assessment and arboricultural method statement should be
  • Prepared by a suitably qualified arboriculturist who has gained expertise in the field of trees in relation to construction

Householder applications

  • Scaled plan accurately positioning the trunks of trees that could influence or be affected by the development (including works such as site access, service routes and site compounds), identified with a reference number (such as T1, T2) and species listed by common name, their stem diameter when measured at 1.5 metres above ground, and whether they are to be removed or retained
  • Any pre-development tree surgery works
  • Compensatory planting for any removed trees

If any of the trees are covered by a Tree Preservation Order or are within a conservation area, then the level of requirements for a Full planning application will apply.

Hedges

The British Standard 5837:2012 only relates to trees and the presence of hedges on an application site does not require such a Survey/Assessment. However all hedges should be shown on the site plan and the impact of development on hedges should be identified.
