Webinar Description:
This seminar will focus on modern, data-driven approaches to assessing tree structural integrity, particularly for high-value landscapes such as hotel properties, public spaces, and campuses. Key topics will include:
• Fundamentals of tree biomechanics and structural failure
• What is Sonic Tomography
• How sonic tomography technology works and its application in the field
• Case studies from urban landscapes, including risk mitigation strategies
• Practical insights for landscape managers, property developers, and municipal teams
The session is designed to equip landscape professionals with actionable knowledge on integrating advanced diagnostics into tree management decisions, reducing liability, and preserving valuable green assets.
Learning Objectives:
1. Recognize the importance of tree structural integrity and how it impacts safety, liability, and asset value in high-profile landscapes.
2. Understand the basic principles of tree biomechanics and recognize the common warning signs of structural failure in urban and landscaped settings.
3. Understand the role of advanced diagnostic tools like sonic tomography in identifying hidden tree risks before failure occurs.
