Why Trees Fail – The Physics of Windstorm Tree Failure

April 17 @ 1:15 pm - 5:00 pm
Instructor: Jim Flott CEUs: 3.5 ALMTU / 1.5 B-S, 1.0 B-P, 1.0 B-M

PNW-ISA is hosting two workshops in Anchorage. Take advantage of a morning or afternoon workshop on April 17. Enroll in BOTH and get $25 off the cost of the afternoon workshop.

Description

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 Understanding why trees fail involves application of this recent research in order to discard outdated beliefs, generalizations, anecdotes, and industry myths and misinformation.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: Atwood Conference Center, Rooms 102 and 104, 550 West Seventh Ave, Anchorage, AK 99501

  • 1:15pm – 2:45pm
    • 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
    • Weather impacts: Types of weather patterns associated with tree failures, wind dynamic effects on tree failure
  • 2:45pm – 3:00pm, Break
  • 3:00pm-5:00pm
    • Tree biomechanics: Connecting tree biology to engineering principles in relation to failure in storm events
    • Arboriculture practices and structural defects: Applying principles learned today for use in practice.
