Focusing on the CTLA Trunk Formula Technique (TFT), this workshop gives an overview of the appraisal process and provides an opportunity to practice in the field. Participants will review common mistakes and refine their craft as appraising arborists.

The first portion of the course is a lecture that discusses the primary components of TFT and a short history of the changes made from the 9th Edition to the 10th Edition of the Guide for Plant Appraisal. The second half of the course is a field application of the concepts discussed in the lecture. Participants will divide into groups and appraise several trees. The class will reconvene and discuss the results.
