Question 1

The 'growing stock' of a forest refers to:

Accepted Answer

The total volume of live trees in a defined area

Answer

Growing stock is the standing volume of all live trees (above a minimum size) within a defined forest area at a given point in time.

Question 2

When using a Bitterlich angle gauge (wedge prism) with a basal area factor (BAF) of 10, each 'in' tree represents how many square feet of basal area per acre?

Accepted Answer

10 sq ft/acre

Answer

Each tree tallied as 'in' using a BAF 10 prism contributes 10 square feet of basal area per acre to the stand estimate.

Question 3

What is the primary difference between 'net volume' and 'gross volume' of a log?

Accepted Answer

Gross volume is total wood including defects; net volume excludes defects

Answer

Gross volume includes all wood regardless of quality, while net volume subtracts defect deductions to reflect merchantable wood only.

Question 4

An increment core extracted from a tree is used to determine:

Accepted Answer

The tree's age and radial growth rate

Answer

An increment core contains annual rings that reveal the tree's age and the rate of radial (diameter) growth over time.

Question 5

Which of the following best describes 'stand density index' (SDI)?

Accepted Answer

A measure of stocking based on number of trees and their average diameter

Answer

SDI (Reineke's SDI) relates the number of trees per acre to the quadratic mean diameter to quantify stand density relative to maximum capacity.
