,Q1. A forester uses a 10-factor prism in a point sample. At one point, six trees are
counted as 'in': dbh 12, 14, 16, 18, 20, and 22 inches. What is the estimated basal area
per acre (sq ft/ac) at that point?
A. 60
B. 120
C. 180
D. 240
Correct Answer: A. 60
Rationale: Each tree counted contributes an amount equal to the basal area factor (BAF)
in sq ft/ac. With 6 trees and BAF=10, BA/ac = 6 × 10 = 60 sq ft/ac. Options B, C, and D
result from misapplying the BAF or double-counting.
Why Wrong:
B - Incorrectly multiplying 6 × 20 (perhaps confusing prism factor with plot radius).
C - Incorrectly using an average dbh to compute basal area separately.
D - Incorrectly squaring the count or adding an extra factor.

Q2. In a southern Appalachian hardwood forest, the objective is to maintain
shade-tolerant species such as sugar maple and beech while also regenerating
intermediate-shade-tolerant oaks. Which regeneration method is most appropriate?
A. Clear-cutting
B. Shelterwood with reserves
C. Group selection
D. Single-tree selection
Correct Answer: C. Group selection
Rationale: Group selection creates gaps of moderate size that allow sufficient light for oak
regeneration while maintaining shade-tolerant species in the matrix. Single-tree selection
favors shade-tolerant species, and clear-cutting eliminates them. Shelterwood with
reserves may not provide enough light for oaks.
Why Wrong:
A - Clear-cutting removes all tree cover, eliminating shade-tolerant species and
favoring intolerant pioneers.
B - Shelterwood with reserves still retains substantial shade, limiting light for oak
regeneration.
D - Single-tree selection creates small gaps that favor shade-tolerant species over
oaks.

, Q3. Southern pine beetle (Dendroctonus frontalis) outbreaks are typically triggered
by a combination of which of the following factors?
A. High stand density, drought stress, and presence of lightning-struck trees
B. Low stand density, excessive rainfall, and fire suppression
C. High genetic diversity, mixed species, and cool temperatures
D. Low basal area, frequent prescribed fire, and high nitrogen deposition
Correct Answer: A. High stand density, drought stress, and presence of
lightning-struck trees
Rationale: Outbreaks are favored by dense stands (high competition), drought stress
(reduced tree defenses), and lightning strikes that provide entry points for beetles. Low
density, fire, or high diversity typically reduce outbreak risk.
Why Wrong:
B - Low stand density and excessive rainfall reduce stress and beetle activity; fire
suppression alone is not a trigger.
C - High diversity and cool temperatures inhibit SPB population growth.
D - Low basal area and frequent fire reduce outbreak potential; high nitrogen may
increase resin production.

Service Gen. Tech. Rep. SRS-140.
Q4. Under the North Carolina Forest Practice Guidelines (FPGs), what is the
minimum streamside management zone (SMZ) width (each side) required for an
intermittent stream where the adjacent slope exceeds 20%?
A. 30 feet
B. 50 feet
C. 70 feet
D. 100 feet
Correct Answer: C. 70 feet
Rationale: The NC FPGs mandate a minimum SMZ width of 50 feet each side for
intermittent streams under average slopes; however, when slopes exceed 20%, the width
increases to 70 feet to ensure adequate sediment filtration and stream protection.
Why Wrong:
A - 30 feet is below even the base minimum for intermittent streams.
B - 50 feet applies only to slopes 20%; steeper slopes require wider SMZs.
D - 100 feet is beyond the required width for intermittent streams; that width may
apply to perennial streams or special conditions.
