BS5837 Tree Survey

The objective of the British Standard is to achieve a harmonious relationship between trees and structures that can be sustained in the long term. EMEC Arboriculture therefore works closely with clients to determine potential conflicts between trees and site proposals while providing objective recommendations for tree removal, protection measures around retained trees and appropriate mitigation.

Survey

A tree survey in accordance with 'BS5837:2012 Trees in relation to design, demolition and construction - Recommendations' is often required at an early stage of the project design to ensure the majority of conflicts between trees present on site and the proposed development can be addressed at the design stage rather than causing issues further down the line.

The survey involves assessing all trees on and within impacting distance of the development and is based on their quality and benefits within the context of the proposed development. The health and expected life span of the trees is assessed and they are subsequently categorised based on their quality or are highlighted for removal.

Report

EMEC Arboriculture presents the results of the survey in a clear, concise report with trees referenced within a tree survey data table which includes root protection area (RPA) calculations. An assessment of the site's arboricultural value is made and any potential arboricultural constraints are outlined. The constraints are then presented on a Tree Constraints Plan which is coloured and presented in accordance with BS5837. All plans are produced in AutoCAD and can be provided in DWG format.

Arboricultural Impact Assessment

This is required to fully assess the impacts of the proposed works on the trees on site. It is designed to evaluate the impact of any tree loss and/or pruning while taking into account mitigation tree planting. It also evaluates the potential impacts of the development on the trees to be retained while outlining preliminary mitigation recommendations and the points which need to be addressed within an arboricultural method statement.
