Format
Unverified; varies by state. Typically a preliminary objective paper, a written main examination including forestry or science optional papers, and an interview, plus physical tests.
Unverified: no state syllabus was opened. ACF is the entry rank of the State Forest Service; officers can later be promoted into the Indian Forest Service. Some states examine through a combined state services exam with a forest-service stream rather than a separate exam.
Original questions written to this exam's published syllabus and pattern. Not past papers.
1. A pine plantation is clear-felled and will be replanted next season. Under FRA definitions the area is:
Deforested, because canopy cover has fallen below 10%
Other wooded land until trees again exceed 5 m in height
Other land until the replanted trees reach full canopy
Still forest, because its land use has not changed
Answer and working
D. Still forest, because its land use has not changed
FRA forest is a land-use definition; areas temporarily unstocked after harvest and expected to regenerate remain forest. Deforestation requires conversion to another land use.

2. Which tissue consists of dead cells with thick, lignified walls?
Parenchyma
Collenchyma
Meristem

4. A bleached, ash-grey E horizon over a dark reddish B horizon enriched in iron, aluminium and humus is typical of:
Podzolisation
Laterisation
Calcification
Salinisation
Answer and working
A. Podzolisation
Organic acids from acid litter mobilise Fe and Al from the E and deposit them in the spodic B. Laterisation leaves Fe and Al oxides throughout a red profile.

5. Why are frost pockets found in valleys and hollows?
Valleys receive less sunlight at midday than slopes
Dense cold air drains downslope and pools there
Soil in hollows is always frozen beneath the surface
Warm air sinks into valleys and is replaced by cold air
Answer and working
B. Dense cold air drains downslope and pools there
Cold, dense air flows downhill on calm nights and collects in low ground, producing much lower minima.
