Matching Exercise 1: Planting Site Requirements and Design Solutions
Timestamp Reference: 19:01 – 25:14 (primary coverage area)
Type: Timing-Practice
Instructions: Match each site design concept or measurement in Column A with its correct description or specification from Dr. Klein’s presentation in Column B. Column B contains two extra items.
| # | Column A | Column B | |
|---|---|---|---|
| 1 | Live oak planting strip width (69” DBH) | a) Four feet past the visible trunk flare | |
| 2 | Laurel oak planting strip width (54” DBH) | b) 3 feet | |
| 3 | Crape myrtle planting strip width (8” caliper) | c) Allow roots to extend both directions toward neighboring trees | |
| 4 | Zone of rapid taper extent | d) 16 feet | |
| 5 | Trunk flare planting space formula | e) 14 feet | |
| 6 | Planting strip (best case root benefit) | f) Trunk flare diameter plus four feet on each side | |
| 7 | Suspended sidewalks example city | g) Austin, Texas | |
| 8 | Silva Cells | h) 8 feet | |
| i) Allow more root growth below surface materials | |||
| j) Structural soils mixed with organic matter |
Answer Key:
1 → d, 2 → e, 3 → b, 4 → a, 5 → f, 6 → c, 7 → g, 8 → i
Source in transcript:
- Planting strip widths: ~23:07–23:39 (Koeser’s research on Tampa street trees)
- Zone of rapid taper: ~22:25 (four feet past visible trunk flare)
- Planting space formula: ~23:00 (trunk flare diameter + 4 ft each side)
- Planting strip root benefit: ~19:01 (roots extending both directions)
- Austin suspended sidewalks: ~24:55–25:07
- Silva Cells: ~24:26–24:46 (allowing root growth, preventing surface damage)
Matching Exercise 2: Root Defects and Planting Procedures
Timestamp Reference: 34:00 – 40:47 (primary coverage area)
Type: Timing-Practice
Instructions: Match each planting practice or root issue in Column A with its correct description or recommendation from Dr. Klein’s presentation in Column B. Column B contains two extra items.
| # | Column A | Column B | |
|---|---|---|---|
| 1 | Root ball shaving | a) Can girdle the trunk if not removed; treat same as synthetic burlap | |
| 2 | Radial slicing | b) Preferred root defect correction — remove a couple inches from outside and bottom | |
| 3 | Volcano mulching | c) Plant a couple of inches above grade to account for settling | |
| 4 | Proper planting depth | d) Results from trees left in containers too long; roots follow container wall shape | |
| 5 | Container root imprints | e) Can promote root defects as mulch breaks down into soil against the trunk | |
| 6 | Synthetic materials (burlap, twine) | f) Better than doing nothing, but may cut a circling root where it continues the circle | |
| 7 | Soil ring around root ball | g) Retains moisture from rain or irrigation over the root zone | |
| 8 | Girdling root consequence | h) Dig the hole three times wider than the root ball | |
| i) Tree can die four to five years after planting from being choked out | |||
| j) Apply 4–6 inches for maximum weed suppression |
Answer Key:
1 → b, 2 → f, 3 → e, 4 → c, 5 → d, 6 → a, 7 → g, 8 → i
Source in transcript:
- Root ball shaving: ~39:03–39:37 (preferred method, remove outside and bottom)
- Radial slicing: ~39:20–39:37 (may cut at a point where circling continues)
- Volcano mulching: ~40:40–40:47 (root defects from mulch breakdown)
- Planting depth: ~36:01–36:16 (couple inches above grade, settling)
- Container root imprints: ~37:17–37:39 (left in container too long)
- Synthetic materials: ~38:44–38:49 (remove to prevent girdling)
- Soil ring: ~39:59–40:05 (moisture retention over root ball)
- Girdling root consequence: ~37:47–37:58 (death four to five years out)
Matching Exercise 3: Tree Management Across Life Stages
Timestamp Reference: 41:03 – 47:15 (primary coverage area)
Type: Timing-Practice
Instructions: Match each tree management concept or term in Column A with its correct description from Dr. Klein’s presentation in Column B. Column B contains one extra item.
| # | Column A | Column B | |
|---|---|---|---|
| 1 | Structural pruning goal (young trees) | a) Mostly heartwood; cannot respond to large wounds as effectively | |
| 2 | Mature tree tissue composition | b) Reduce competition with the central leader and space scaffolding branches | |
| 3 | Pruning wound size (young trees) | c) Two and a half day course in Florida for standardized pruning communication | |
| 4 | Mature tree pruning focus | d) Small half-inch cuts that set the tree up for two to three years | |
| 5 | Bark inclusion | e) Manage loading on the exterior canopy; cuts at three to five inches | |
| 6 | ANSI A300 | f) Failure point where two stems rub with no connective tissue between them | |
| 7 | Prescription pruning qualification | g) Pruning standards — guidance for best practices in tree care operations | |
| 8 | Three phases of tree life | h) Growth phase, maintenance phase, death phase with natural retrenchment | |
| i) Annual inspection required by state law for all municipal trees |
Answer Key:
1 → b, 2 → a, 3 → d, 4 → e, 5 → f, 6 → g, 7 → c, 8 → h
Source in transcript:
- Structural pruning goal: ~41:28–41:50 (dominant leader, scaffolding branches, reducing competition)
- Mature tissue composition: ~45:47–45:51 (mostly heartwood vs. younger sapwood)
- Pruning wound size: ~41:51–41:59 (half-inch cuts, two to three year intervals)
- Mature pruning focus: ~46:08–46:14 (exterior canopy, small cuts)
- Bark inclusion: ~46:22–46:32 (no connective tissue, two stems rubbing)
- ANSI A300: ~47:03 (pruning standards reference)
- Prescription pruning: ~47:03–47:08 (two and a half day course)
- Three phases: ~46:06–46:07 (growth, maintenance, death/retrenchment)
