Question 1

Which of the following is a key advantage of using a cable yarding system over ground-based skidding in steep terrain?

Accepted Answer

Reduced soil disturbance and erosion on slopes exceeding 35%

Answer

Cable yarding suspends logs above the ground during extraction, significantly reducing soil compaction and erosion on steep slopes where ground-based equipment is unsafe.

Question 2

A forester is using the Doyle Log Rule to estimate board footage. Compared to actual yield, the Doyle Rule tends to:

Accepted Answer

Overestimate volume in large logs and underestimate in small logs

Answer

The Doyle Rule overestimates large-log volume and significantly underestimates small-log volume due to its mathematical formula's limitations.

Question 3

Which certification standard is most widely used by US forest landowners to demonstrate sustainable forest management to markets?

Accepted Answer

Forest Stewardship Council (FSC) or Sustainable Forestry Initiative (SFI)

Answer

FSC and SFI are the dominant third-party forest management certification systems in the US, recognized by timber markets and buyers.

Question 4

What is the primary function of a Best Management Practice (BMP) for stream-side buffers in timber harvesting?

Accepted Answer

To protect water quality by filtering sediment and maintaining stream temperature

Answer

Streamside management zones with vegetated buffers trap sediment, prevent bank erosion, and provide shade that regulates water temperature for aquatic species.

Question 5

In pine plantation management in the US South, 'site preparation' before planting typically includes:

Accepted Answer

Mechanical or chemical control of competing vegetation to improve seedling survival

Answer

Site preparation reduces competition from brush, grasses, and hardwoods so that planted pine seedlings have improved access to light, water, and nutrients.
