About the Course

This two-day course includes accreditation. Delegates will be guided through a number of sample case studies, and shown how to value specimens using the most common models. The course aims to show delegates the value of trees within the environment as part of a wider perspective. The course provides everything necessary to enable attending delegates to start writing professional tree valuation reports. It also provides new insights and recent findings for veteran valuers to bring them up to speed.

Content: This two-day course explores the main valuation techniques for trees, their merits and limitations.  It explores the legal framework in which valuation should occur.  Common pitfalls are identified so that the user is informed.  Scenarios are examined.

The candidate is informed when valuing amenity trees which methods to use.

The course includes assessment.  Candidates who successfully complete this will have attained one of the Areas of Professional Competency recognised by the Consulting Arborist Society.

Who is this course for?  Arborists for whom valuing trees is part of their remit, tree officers, consultants, land managers etc.

What are the benefits? There is a tendency for existing courses to explore the merits of specific valuation techniques.  This course provides an informed, impartial appraisal and gives the valuer the tools needed to make a defendable valuation.

Existing Skills Needed: No formal qualifications are needed, but an appreciation of tree health is useful


Attendance to both days of the course is essential for accreditation. Successful delegates will be certified to apply the four valuation techniques as applicable to a series of case studies. Successful completion of the course will qualify Professional CAS Members for inclusion in the Tree Valuation category of the member’s database
