TIMESTAMP-LINKED REVIEW PROMPTS

These short review tasks direct students to specific video segments for focused self-paced study. They can be used as Moodle forum prompts, journal entries, or pre-quiz preparation activities.

Review Task 1

Watch: 5:44 – 9:35 Task: Identify the three data sources Dr. Klein uses to illustrate how climate change is affecting urban tree management in the Southeast. Key Points to Identify:

  • The hardiness zone shift for Athens, Georgia (from what zone to what zone, and projected future)
  • The University of Maryland climate analog tool and what it projects for Athens in 60 years
  • The factor Klein identifies as more important than warm temperatures when deciding whether to plant species from further south

Review Task 2

Watch: 19:01 – 24:18 Task: Summarize the relationship between planting space size and long-term tree survival. Include specific measurements Dr. Klein cites. Key Points to Identify:

  • The trunk flare planting space formula (trunk flare diameter + four feet on each side)
  • The specific planting strip widths required for live oak, laurel oak, and crape myrtle based on Koeser's research
  • What happens when trees outgrow their planting space (sidewalk lifting, lawsuits, trunk flare damage during sidewalk replacement)

Review Task 3

Watch: 34:00 – 40:47 Task: List the key steps Dr. Klein describes for properly planting a container-grown tree, from hole preparation through mulching. Key Points to Identify:

  • Hole width guidance for good soil vs. poor soil
  • Proper planting depth relative to grade and why
  • Root defect correction method (shaving vs. slicing) and why shaving is preferred
  • Mulch depth, ring diameter, and the specific practice to avoid

Review Task 4

Watch: 41:03 – 46:40 Task: Compare Dr. Klein's pruning recommendations for newly planted trees versus mature trees. Explain why the approach differs. Key Points to Identify:

  • The goal of structural pruning on young trees (dominant leader, scaffolding branches, reducing codominant stems)
  • The size and frequency of cuts Klein recommends for young trees
  • Why mature trees require a different approach (heartwood vs. sapwood composition)
  • Where on the canopy mature tree pruning should focus and what cut sizes are appropriate

Review Task 5

Watch: 9:36 – 12:47 Task: Explain Dr. Klein's argument for why cities should complete tree inventories before a hurricane strikes rather than only assessing damage afterward. Key Points to Identify:

  • What front-end data is missing without a pre-storm inventory
  • Why post-storm assessments that only document species failures are insufficient
  • The additional variables Klein identifies that affect whether a tree fails (management inputs, nursery stock quality, site conditions)
