This review and study of tree biomechanics will begin with basic tree biology as it impacts and responds to defects and conditions. Structural root growth, flexure wood, woundwood, CODIT and how environment impacts tree integrity will be discussed.
The next step will be a review of tree biomechanics from roots to crown to understand how trees stand and why they fall. A study the form of the tree to consider its influence on dynamic response in winds and differences in tree morphology that can produce extreme behaviors, such as critical dissipation of stem oscillations. Live crown ratio, lever arm, over-extended trees and branches, height/diameter ratio, crown form and crown class will be explored as they impact likelihood of failure.
Finally, we will explore identification and assessment of various defects and conditions that impact the likelihood of tree or tree part failure. This will focus on identification, diagnosis interpretation of various defects and conditions through group exercises reviewing and rating examples. Examples will include, but are not limited to, species defects/failure patterns, dead and dying branch or tree, weak attachments, lean, decay and cavities, cracks, root damage/disease and restriction, root cutting and critical root zone.
This program is designed and presented to provide attentive attendees with enhanced understanding and guidance in tree biomechanics and rating of likelihood of failure to increase reliability and confidence.
No prior certifications are required to attend this class; however, a working understanding of tree biology basics is recommended.
