Question 1

A forester notices that regeneration success rates vary significantly across planting crews. Which QA tool is best suited to investigate whether the variation is random or due to a specific assignable cause?

What is a 'quality objective' in the context of a forestry management system?

Accepted Answer

A measurable goal set to achieve quality policy targets

Question 4

Which sampling method is most appropriate when a forester needs to assess herbicide application quality across a large, heterogeneous treatment unit?

Accepted Answer

Stratified random sampling

Answer

Stratified random sampling divides the unit into subgroups (strata) by vegetation type or slope, then randomly samples each, ensuring all areas are represented.

Question 5
