Assessing and Managing Aging Urban Trees Scott Hartman Philip Van Wassenaer

While aging urban trees provide a wealth of benefits to the residents who live amongst them, they may also begin to pose more risk, and as urban centres become increasingly dense, trees, people and infrastructure often come into conflict. Balancing these competing interests while looking out for the trees can be a real challenge. Today’s arborists can choose from a wealth of methods to better manage and assess the risk of trees. The recently introduced ANSI A300 Part nine describes three levels of risk assessment. By presenting a series of case studies, Philip van Wassenaer will focus on how advanced risk assessment methods (Level 3) are being used to better understand the likelihood of failure and to contribute useful information used in the development of conservation management strategies for aging and significant urban trees
