Instructed by Dr. Julian Dunster. Registration includes a copy of Julian Dunsters book Documenting Evidence. Documenting Evidence covers the professional practice of recognizing and understanding evidence, and learning how to effectively use it in reports. It applies to tree care companies and climbers, municipal, utility, and consulting arborists - anyone working with trees who may later need to explain what was done on any given day. Arborists routinely examine trees for health and risk. The assignment may involve site review, or checking a tree before pruning or removing it. Perhaps it involves collecting data to report about appraisal of damage or trespass issues, or forensic investigations about injuries caused by falling trees. This course covers the professional practice of recognizing and understanding evidence, and learning how to effectively use it in reports. In every case, from the routine to the unusual, the arborist needs to clearly understand the practical and intellectual process of documenting what was seen on site. Before the course, participants are encouraged to submit case studies for class discussion. Selected examples will be used as a group exercise to examine strengths and weaknesses and suggest ways in which we can improve our professional practice.
