BS5837 Tree Surveys

When is a BS5837 Tree Survey required?

A suitably designed scheme (extension, new build, demolition, development proposal etc.) which is deemed acceptable by your local authority tree department cannot be achieved without first assessing the site’s arboricultural constraints.

Where trees are located within the site boundary or on the adjacent land i.e. trees within impacting distance of the site (15m distance from site boundary is often used by the Local Planning Authority), a BS5837:2012 compliant Tree Assessment (Tree Survey and Tree Report) is required.

The BS5837 Tree Survey, Advice and Tree Report should be prepared by a suitably Qualified Arboriculturist (Tree Consultant / Arboricultural Consultant) and will allow for a realistic understanding of the site and the limitations presented from trees; an acceptable design will successfully incorporate the suitable trees without damage or future conflict and mitigate the loss of any trees being removed.

Ultimately, the local authority tree department will need a BS5837 Assessment in order to inform their decision making process. The current British Standard BS5837:2012 ‘Trees in relation to Design, Demolition and Construction – Recommendations’ (4th Edition, came into effect on 30 April 2012 and supersedes BS5837:2005) outlines the requirement for an Arboriculturist to undertake a Tree Survey, Tree Constraints Plan and Tree Report to guide the design. Thereafter, and in relation to the final scheme, an Arboricultural Implications Assessment with Method Statement considerations and ‘Draft’ Tree Protection Plan are typically required.

The specific tree related planning policies and/or supplementary planning guidance can be found via the council’s specific website sections, your local authority links will be coming here soon.
