Why Trees Fail – The Physics of Windstorm Tree Failure

July 31 @ 12:30 pm - 3:45 pm
Instructor: Jim Flott CEUs: 3.0 ALMT / 0.5 B-S, 1.0 B-P, 1.5 B-M Registration Fees: $50.00 - $100.00

PNW-ISA is hosting two Boise workshops on July 31. Enroll in BOTH to get $25 off. Use PROMO CODE: BOISE2020

This workshop provides a solid foundation for arborists of all skill and experience levels to aid in assessing why trees fail in storm events and improves their ability to assess risk.

There has been a proliferation of tree anchorage and tree biomechanics research in the last decade. Understanding why trees fail involves application of this recent research in order to discard outdated beliefs, generalizations, anecdotes, and industry myths and misinformation. Tree, root, and crown attributes, loads, weather, and tree biomechanics will be discussed in relation to wind storms.

The workshop and discussion will review, synthesize and integrate several research findings to try to understand how and why some trees fail, some do not, and some break along the trunk, while others uproot.

Schedule

Location: Idaho State Museum, Idaho Room, 610 Julia Davis Drive, Boise, ID 83702

  • 12:30pm – 1:30pm
    • Root strength, architecture and tree anchorage: Tree anchorage, tree form, root attributes characterized in relation to wind forces
    • Tree failure patterns: Discussion and illustration of the types of tree failures in storm events

  • 1:45pm-3:45pm
    • Tree biomechanics: Connecting tree biology to engineering principles in relation to failure in storm events
