Arboricultural Impact Assessment System

AIA system - Guidance & Training

With a significant amount of research and testing behind it, the launch of new impact assessment training and guidance is here. The new AIA system embraces current thinking, raises our professional status and safeguards users by providing a framework and structure that allows informed, robust decision-making.

The AIA system has been developed to provide Tree Officers & Consultants with a level playing field. The system is transparent, repeatable and based on valid research.

The system is designed to inform decisions, not to override expert opinion.

The AIA system training is currently being delivered in-house to private organisations and will be offered to the wider arboricultural community in the near future.

Guidance Notes for Tree Officers & LPAs

The research findings have identified consistent flaws in the arboricultural information submitted with planning applications. Alongside the new AIA training there are several freely available guidance publications currently being prepared for distribution to LPAs. The guidance includes:

  • Key issues & common failings

  • Checking submitted information for compliance with BS5837

  • Review of technical details

  • Useful research & references by key issue

The guidance enables quick document review by simple checks and provides key details and reference points for efficient assessment and robust critique of submitted tree information.
