SAF Forest Resource Management & Planning 3

Question 1

The concept of 'forest regulation' in classical forest management refers to:

Accepted Answer

Adjusting the age-class distribution to achieve a regulated or normal forest

Answer

Forest regulation means organizing age classes and stocking so that equal volumes can be harvested annually or periodically on a sustained basis.

Question 2

A site index of 85 (base age 50) for a loblolly pine stand indicates:

Accepted Answer

Average dominant tree height of 85 feet at age 50

Answer

Site index is defined as the average height of dominant and co-dominant trees at a specified base age, commonly 50 years for southern pines.

Question 3

When preparing a timber sale, a forester marks trees using the 'leave tree' marking method. What is the main objective?

Accepted Answer

Mark trees to retain for future crops, residual stocking, or wildlife

Answer

Leave tree marking designates which trees stay after harvest to meet stocking, quality, wildlife, and future crop objectives.

Question 4

Which harvesting system typically results in the lowest soil disturbance and is most appropriate on steep or erosion-prone terrain?

Accepted Answer

Cable yarding (skyline)

Answer

Cable yarding systems suspend logs off the ground during extraction, greatly reducing soil compaction and erosion on steep slopes.

Question 5

A stand exam reveals regeneration is inadequate after a shelterwood seed cut. The most likely corrective action is:

Accepted Answer

Conduct a fill planting or site preparation followed by planting

Answer

When natural regeneration fails to meet stocking standards, foresters typically intervene with fill planting or site preparation and artificial regeneration.
