CTSP Risk Assessment 5

Question 1

Which environmental condition should prompt a CTSP to increase inspection frequency for high-value trees?

Accepted Answer

Prolonged drought followed by heavy rainfall

Answer

Prolonged drought weakens root systems, and subsequent heavy rain saturates soil, dramatically increasing failure risk.

Question 2

A dead branch hanging in the canopy of a live tree is commonly called what?

Accepted Answer

A widow maker

Answer

A 'widow maker' is a dead or broken branch lodged in the canopy that can fall unpredictably, posing serious injury risk.

Question 3

When documenting a tree risk assessment, which information is LEAST critical to include?

Accepted Answer

The tree's commercial nursery purchase price

Answer

A tree's purchase price is irrelevant to its structural risk and is not a component of a standard risk assessment report.

Question 4

A CTSP performs a risk assessment and assigns a 'low' likelihood of failure but 'significant' consequences. What is the appropriate overall risk level?

Accepted Answer

Moderate

Answer

The ISA matrix combines low likelihood with significant consequences to yield a moderate overall risk rating.

Question 5

Which of the following is a sign that a tree may have been previously topped, increasing its current risk?

Accepted Answer

Multiple large, weakly attached epicormic sprouts at former cut sites

Answer

Topping causes flush regrowth of weakly attached epicormic sprouts that are prone to failure as they grow large.
