A BS 5837:2012 compliant tree survey is essential for most development projects. It determines the retention categories of all trees on the development site, highlighting any high-value trees that may pose a planning constraint and any low-quality trees that can be removed or mitigated for. The survey will assess the quality of any significant vegetation that may represent a constraint and will record all arboricultural features including trees, groups of trees, hedgerows and woodland. In most cases, it is necessary for the validation of a planning application.

A certified arboriculturist will undertake an assessment of tree physiology and structural condition, attributing each feature to a BS 5837:2012 retention category in accordance with the tree’s amenity value and its remaining life expectancy. The survey and assessment will note any structural defects, physiological dysfunction and observable diseases affecting the trees. Depending on the condition of each tree, appropriate preliminary recommendations for tree management will be provided.

The survey will be based on topographical information and will record the dimensions of vegetation, including architectural features such as stem locations and diameters, tree heights, crown spreads and calculated root protection areas. This information can then inform the design layout and feed into feasibility assessments. It is recommended that surveys are undertaken at the earliest opportunity, so that any conflicts with existing trees can either be avoided, designed around or planned for. Our arboricultural consultants can meet with the design team on site to identify any initial constraints and discuss potential design solutions.
