Sample Question 1
Forest Mensuration & Inventory EASY • MULTIPLE_CHOICE
Diameter at Breast Height (DBH) of standing trees is internationally measured at:
A 1.00 meter
B 1.37 meters (4.5 feet) / 1.30 meters
C 0.50 meter
D 2.00 meters
✓ Correct Answer: B - 1.37 meters (4.5 feet) / 1.30 meters
📖 Step-by-Step Solution & Conceptual Rationale:
DBH is standardized to avoid basal root flare distortion.
Sample Question 2
Forest Mensuration & Inventory MEDIUM • MULTIPLE_CHOICE
Which instrument measures tree height using trigonometric principles?
A Planimeter
B Dendrometer band
C Clinometer / Abney level / Haga altimeter
D Calliper
✓ Correct Answer: C - Clinometer / Abney level / Haga altimeter
📖 Step-by-Step Solution & Conceptual Rationale:
Clinometers measure vertical elevation angles to calculate height.
Sample Question 3
Forest Mensuration & Inventory MEDIUM • MULTIPLE_CHOICE
The basal area (BA) of a single tree from diameter (d) in meters is:
A BA = π * d²
B BA = 2 * π * d
C BA = (π / 4) * d²
D BA = (π / 2) * d
✓ Correct Answer: C - BA = (π / 4) * d²
📖 Step-by-Step Solution & Conceptual Rationale:
Basal area is the cross-sectional stem area at breast height.
Sample Question 4
Forest Mensuration & Inventory HARD • MULTIPLE_CHOICE
The ratio of actual tree volume to a reference cylinder of same base DBH and height is:
A Shape coefficient
B Taper index
C Form Factor
D Bark factor
✓ Correct Answer: C - Form Factor
📖 Step-by-Step Solution & Conceptual Rationale:
Form factor corrects cylinder volume for natural stem taper.
Sample Question 5
Forest Mensuration & Inventory HARD • MULTIPLE_CHOICE
Current Annual Increment (CAI) equals Mean Annual Increment (MAI) at:
A Zero volume
B The age of maximum MAI (Rotation of maximum volume production)
C Stand senescence
D Stand establishment
✓ Correct Answer: B - The age of maximum MAI (Rotation of maximum volume production)
📖 Step-by-Step Solution & Conceptual Rationale:
CAI intersects MAI at its peak, defining biological rotation age.
