CTSP Risk Assessment 4

Question 1

Which advanced diagnostic tool uses sound wave pulses to create a cross-sectional map of wood density inside a trunk?

Accepted Answer

Sonic/acoustic tomography

Answer

Sonic tomography sends sound pulses between sensors placed around the trunk to map internal wood density and detect decay.

Question 2

A CTSP finds that a tree's root plate has lifted on one side after recent wind events. What does this indicate?

Accepted Answer

The root system has been compromised and failure risk is elevated

Answer

A lifted root plate indicates the tree's anchoring roots have failed or been damaged, significantly increasing overturn risk.

Question 3

Under the ISA's three-level assessment system, which level is appropriate when a Level 1 walkby reveals a potential problem?

Accepted Answer

Level 2 – Basic Assessment

Answer

A Level 2 Basic Assessment is the appropriate follow-up when a Level 1 walkby identifies a concern requiring closer examination.

Question 4

Which of the following soil conditions most increases the risk of wind-throw for a large tree?

Accepted Answer

Shallow, compacted, or saturated soil limiting root depth

Answer

Shallow, compacted, or saturated soils prevent deep root anchorage, greatly increasing vulnerability to wind-throw.

Question 5

A CTSP is evaluating a tree with significant trunk lean. Which measurement helps determine if the lean is a structural concern?

Accepted Answer

The degree of lean relative to trunk diameter and root depth

Answer

Lean severity is assessed relative to trunk size and the root system's capacity to counteract the off-center load.
