The Internal Tree Inspection Programme (ITIP) is a two-day training course designed to equip arboriculturists with the skills to assess the internal condition of trees using visual tree assessments, tomography and the microdrill. Developed in collaboration with industry experts, the course provides hands-on experience with diagnostic tools, enhancing risk assessment and evidence-based decision-making in tree management.
 

The finer details

The course blends classroom learning with practical demonstrations and field exercises, ensuring participants leave with the confidence to apply internal tree inspection techniques professionally.

Day 1 focuses on the role of Visual Tree Assessment (VTA), introducing candidates to the use of diagnostic tools such as sonic and electrical resistance tomography. Participants engage in field exercises, research projects, and hands-on demonstrations to understand the limitations and best practices for tree risk assessment.

Day 2 builds on this foundation with a deeper dive into tomogram interpretation, microdrill analysis, and research-based evaluation of internal decay detection methods. The course combines theoretical learning with extensive practical sessions, ensuring candidates leave with the ability to apply these techniques effectively in real-world scenarios.
