Indian Forest Service Examination (IFoS) — Forestry optional · India · Union Public Service Commission
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)

Choose an answer, then open the working. Each explanation says why the right answer is right and why the others are not.
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 a skyline system, logs are carried by:
A. A carriage running on a cable
The skyline is stretched between tower and tailhold.
A cable skidder brings logs to itself using:
A. Chokers and a winch cable
Grapple skidders pick up bunches directly.
A soil benefit of cut-to-length harvesting is that:
D. Branches form brush mats on machine trails
Brush mats spread load and return nutrients.
Whole-tree systems can supply energy markets because they:
A. Residues pile up at the landing
Residue at landings is easy to chip.
An outsloped road surface sheds water:
A. Towards the downhill side
Insloped roads drain to an uphill ditch.
Full-bench road construction on steep slopes means:
D. Cutting the full width into the slope
It avoids unstable sidecast fill.
In India, round timber has traditionally been measured by:
A. Mid-girth and length
Volume by the quarter-girth (Hoppus) rule or true volume.
Hammer marks on logs in Indian depots are used to:
D. Mark property and identify lots
They identify ownership and legality.
Culverts at stream crossings must be sized mainly for:
B. The design flood and debris
Undersized culverts block and wash out.
