Enhance Your Tree Surveys With Precision UAV Canopy Analysis

Accurate canopy analysis is a critical requirement under the new BS 5837:2025 Code of Practice, which strengthens the protection of trees during development.

The updated tree survey standard now requires consideration of future canopy growth, as well as revised methods for calculating Root Protection Areas (RPAs) and introducing additional buffer zones. This means a precise understanding of existing and projected canopy spread is essential to ensure designs remain compliant both now and in the future.

Ground-based surveys alone often struggle to capture complex canopy structures, especially on large or inaccessible sites. Drone (UAV) technology provides a highly accurate, efficient and non-invasive solution.

All drone operations are carried out in full compliance with Civil Aviation Authority (CAA) regulations. 

Data is interpreted and integrated by qualified arboricultural report partners with in-depth knowledge of BS 5837 standards, including the upcoming 2025 Code of Practice.

We combine leading-edge UAV technology with practical arboricultural expertise to ensure every assessment is robust, reliable and fully aligned with the latest requirements when completing tree surveys.

The forthcoming BS 5837:2025 updates the standard from a set of recommendations to a formal Code of Practice, making compliance a stronger planning requirement. 

Key changes include revised methods for calculating Root Protection Areas (RPAs), the introduction of a mandatory one metre buffer zone around each RPA, and a requirement to consider future canopy growth when designing developments. In addition, the traditional Tree Constraints Plan is being replaced by the new Arboricultural Constraints and Opportunities Plan (ACOP), which emphasises not only protecting existing trees but also integrating them positively into site design. These updates strengthen tree protection and require more precise, forward-looking tree survey data to support planning applications.
