Conference Description:

This conference will combine lectures about depreciation in appraisal, pruning standards, working with hazardous trees and risk assessment with field exercises and discussion. Speakers will take attendees through the background and methods, then apply them to trees in the field. As practitioners, the speakers are in the position of daily assessment and decision-making about appraisal, risk, and pruning. Learn about the new ANSI A300 pruning standard, the 10th edition of the Guide for Plant Appraisal, and that old standby, risk assessment.
