State Forest Service — Assistant Conservator of Forests (state PSC exams) · India · State Public Service Commissions (e.g. TNPSC, MPPSC, UPPSC, HPPSC, KPSC, MPSC)
Original practice questions written to the published syllabus · not past papersGetting wood from stump to mill safely and with least damage: harvest planning, felling and extraction systems, forest roads, transport, ergonomics and reduced-impact logging. The Agricultural Engineering track (aquacultural-forest-engineering) introduces roads and logging machinery in a few units; this subject treats forest operations in full.
In the exams: IFoS Forestry Paper II Section A (surveying and forest engineering); ICAR AICE-JRF 59 Unit 7 (logging and ergonomics); PRC Forest Engineering and Utilization; Korea Forestry Engineer written subject Forest Road Engineering; ICAR AIEEA-PG Group 09 (forest engineering)
State Forest Service and Range Forest Officer exams, India

Choose an answer, then open the working. Each explanation says why the right answer is right and why the others are not.
An operational harvest plan is based mainly on:
D. A pre-harvest inventory and a detailed map
Maps show topography, streams, buffers and trees to fell and retain.
In directional felling, the notch is cut on the side:
C. Facing the intended direction of fall
The back cut is made from the opposite side.
The chain brake on a chainsaw is activated by:
D. The front hand guard or inertia
It stops the chain within a fraction of a second.
In the tree-length system, stems are:
D. Delimbed at the stump, hauled full length
Cross-cutting is done at the landing or mill.
Bucking means:
B. Cross-cutting stems into logs
Bucking decisions strongly affect log value.
In India, round timber has traditionally been measured by:
A. Mid-girth and length
Volume by the quarter-girth (Hoppus) rule or true volume.
FOPS on forest machines protects against:
B. Falling trees and branches
Falling object protective structures.
Reduced-impact logging aims to reduce:
C. Damage to residual stand, soil and water
Planned, controlled harvesting minimises impacts and waste.
Compaction is greatest on:
C. Wet, fine-textured soils
Wet clays deform easily.
Temporary portable bridges on skid trails avoid:
D. Fording streams with machines
Fording damages beds and banks.
