Question 1

In even-aged stand management, a 'pre-commercial thinning' differs from a commercial thinning because:

Accepted Answer

Pre-commercial thinning occurs early when removed trees have no merchantable value, incurring a cost with no immediate revenue

Answer

Pre-commercial thinning is an investment in stand density control before trees reach merchantable size, improving future growth at a short-term cost.

Question 2

Which factor most directly determines the 'site index' of a forest stand?

Accepted Answer

The dominant tree height at a base age (typically 25 or 50 years), reflecting site productivity

Answer

Site index is a measure of forest productivity expressed as the average height of dominant and codominant trees at a specified base age.

Question 3

What is the role of a 'landing' in a timber harvest operation?

Accepted Answer

A designated area where logs are decked, processed, and loaded onto transport trucks

Answer

The landing is a cleared area where skidded or forwarded logs are sorted, delimbed, bucked, and loaded onto trucks for transport to the mill.

Question 4

Under the USDA Forest Service's 10-year forest plan cycle, which document guides site-level timber sale planning and environmental analysis?

Accepted Answer

National Forest Land and Resource Management Plan (Forest Plan) combined with project-level NEPA documents

Answer

The Forest Plan sets strategic direction and standards, while project-level NEPA documents (EAs or EISs) analyze specific timber sales and activities.

Question 5

A forester is evaluating two harvest systems: a cut-to-length (CTL) system and a full-tree system. The CTL system's primary advantage for soil and site protection is that:

Accepted Answer

Slash is distributed throughout the cutblock, protecting soil during extraction and nutrients remain on site

Answer

In CTL harvesting, tops and branches remain in the cutblock as slash mats that protect soil under the forwarder tires and return nutrients through decomposition.
