Deodar forests (12/c.d.) of Uttarakhand and Himachal Pradesh are essentially managed under which system ?
Answer: C
The key gives the Indian irregular shelterwood system.
Deodar (Cedrus deodara) forests of the western Himalaya grow as uneven-aged stands with patches of different ages, and silviculture texts name the Indian irregular shelterwood system as the one suited to them; it works with a long regeneration period and group felling over uneven-aged forest.
Clear felling would be unsuitable on steep slopes because of erosion and poor deodar regeneration, and a regular shelterwood system needs even-aged stands. Web searches did not confirm the system in these words (they only showed regeneration problems in deodar forests), so this rests on standard silviculture texts, which I could not check, and on the key.
