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.

Cost: £595 + VAT

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 practical sessions to understand the limitations and best practices for internal tree inspection.

Day 2 builds on this foundation with a deeper dive into tomogram interpretation, microdrill measurement curve analysis, and research-based evaluation of internal tree inspection 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.

 

The finer details

 

The Internal Tree Inspection Programme (ITIP) is a two-day course combining theory, hands-on practice, and research-led learning. It covers the principles of Visual Tree Assessment (VTA), the use of diagnostic tools such as the PiCUS 3 Sonic Tomograph, PiCUS TreeTronic 3 Electrical Resistance Tomograph, the IML Resi-PD400 Microdrill, the Fractometer II including the interpretation of tomograms and measurement curves.

Day 1 focuses on VTA fundamentals, diagnostic tool demonstrations, research projects, structured field exercises and practical assessment on the PiCUS 3.

Day 2 advances into data interpretation, more research projects, and further practical sessions and assessments on the Microdrill.

Participants engage in interactive discussions, hands-on practical sessions, practical assessments, research projects and a written assessment. 
The course is designed to ensure arboriculturists can confidently apply internal tree inspection techniques in professional practice.
