- A. When crop is partly of coppicing and partly of seedling organ of different age clear
- B. When some selected shoots are selected for retention for future period
- C. When mature crop is removed by clear felling and regeneration is entirely by vegetative methods
- D. None of these
Explanation: In the simple coppice system, the mature crop is clear-felled and the next crop arises entirely from vegetative regeneration such as…
Correct answer: When mature crop is removed by clear felling and regeneration is entirely by vegetative methods1542. Coppice selection means:
- A. When mature crop is removed by clear felling and regeneration is entirely by vegetative methods
- B. None of these
- C. When crop is partly of coppicing and partly of seedling organ of different age clear
- D. When some selected shoots are selected for retention for future period
Explanation: Coppice selection involves retaining selected coppice shoots while removing others, so the retained shoots can develop into the future…
Correct answer: When some selected shoots are selected for retention for future period- A. When mature crop is removed by clear felling and regeneration is entirely by vegetative methods
- B. When some selected shoots are selected for retention for future period
- C. When crop is partly of coppicing and partly of seedling organ of different age clear
- D. None of these
Explanation: Coppice with standards combines a coppice crop with standards, which are trees grown from seed and retained beyond the coppice rotation.
Correct answer: When crop is partly of coppicing and partly of seedling organ of different age clear- A. If canopy is opened out evenly in making regeneration felling
- B. If the canopy is opened out gradually and irregularly with a long regeneration period, resulting in a more uneven aged forest
- C. If the canopy is opened out by creating scattered gaps which are subsequently extended over the whole area
- D. None of these
Explanation: In group shelterwood, regeneration begins in scattered groups or gaps, and these openings are gradually enlarged or extended until the…
Correct answer: If the canopy is opened out by creating scattered gaps which are subsequently extended over the whole area- A. If canopy is opened out evenly in making regeneration felling
- B. If the canopy is opened out by creating scattered gaps which are subsequently extended over the whole area
- C. None of these
- D. If the canopy is opened out gradually and irregularly with a long regeneration period, resulting in a more uneven aged forest
Explanation: Irregular shelterwood opens the canopy gradually and irregularly over a long regeneration period, producing an uneven-aged or irregular…
Correct answer: If the canopy is opened out gradually and irregularly with a long regeneration period, resulting in a more uneven aged forest- A. All of the above
- B. Group shelter wood system
- C. Irregular shelter wood system
- D. Uniform shelter wood system
Explanation: The main forms of shelterwood system are uniform shelterwood, group shelterwood, and irregular shelterwood.
Correct answer: All of the above- A. If the canopy is opened out by creating scattered gaps which are subsequently extended over the whole area
- B. If canopy is opened out evenly in making regeneration felling
- C. If the canopy is opened out gradually and irregularly with a resulting in a more uneven aged forest
- D. None of these
Explanation: Uniform shelterwood opens the overwood canopy relatively evenly across the regeneration area, giving the young crop broadly uniform…
Correct answer: If canopy is opened out evenly in making regeneration felling1548. Lean varies with:
- A. Slope and affects cutting operations
- B. Timber breakage and hang-up are more
- C. None of these
- D. Both (a) & (b)
Explanation: Tree lean is influenced by slope and must be considered during felling because it affects the direction and safety of cutting operations.
Correct answer: Both (a) & (b)- A. All of the above
- B. It should be able to grow easily without any special effort
- C. Species should be tough, hardy, and tolerant of repeated cutting
- D. Species should require no elaborate method of cultivation
Explanation: Species selected for coppice should regenerate readily, grow without elaborate cultivation, and tolerate repeated cutting while remaining…
Correct answer: All of the above- A. Both (a) & (b)
- B. Delay in thinning is not compensated for in terms of girth increment by removing larger volume, unless this volume represents a greater proportion of the growing stock than did the earlier thinning
- C. Average tree size in the remaining crop increases with increasing weight of thinning
- D. None of these
Explanation: Heavier thinning generally leaves fewer trees with more growing space, increasing the average size of the remaining trees.
Correct answer: Both (a) & (b)- A. Nurse
- B. Main
- C. Subsidiary
- D. All of the above
Explanation: Forest crops may be classified by their role as main crops, subsidiary crops, and nurse crops.
Correct answer: All of the above1552. Types of layering are:
- A. Air
- B. Surface or ground
- C. None of these
- D. Both (a) & (b)
Explanation: Layering is commonly divided into ground or surface layering, where a branch is rooted against the soil, and air layering, where roots are…
Correct answer: Both (a) & (b)- A. Both (a) & (b)
- B. When they are felled e.g. Prosopis cineraria
- C. Without any injury e.g. Populus alba and Populus eupharatica
- D. None of these
Explanation: Some species produce root suckers naturally, as in Populus alba and P. euphratica, while injury or felling can stimulate them in species…
Correct answer: Both (a) & (b)- A. In case of bela forest, after feeling the shisham, trenches are made
- B. Both (a) & (b)
- C. In other countries root suckers are produced differently i.e. They expose the roots of the stump and mark very small injuries on the roots on equal distance
- D. None of these
Explanation: Shisham root suckers may be encouraged after felling by trenching in Bela forests, or by exposing stump roots and making small injuries at…
Correct answer: Both (a) & (b)- A. Axe
- B. Saw
- C. Both (a) & (b)
- D. None of these
Explanation: An axe can fell smaller trees and a saw is used for controlled felling, especially of larger trees.
Correct answer: Both (a) & (b)- A. Both (a) & (b)
- B. those which produce root suckers less in number
- C. Those which produce more and vigorous root suckers
- D. None of these
Explanation: Root-suckering species may produce abundant, vigorous suckers or fewer and weaker suckers, depending on species and conditions.
Correct answer: Both (a) & (b)- A. The species (Shisham and Acacia nilotica) produce good and vigorous coppice shoots
- B. Both (a) & (b)
- C. The species (Quercus incana) produce coppices hoots also but they are few and weak
- D. None of these
Explanation: Shisham and Acacia nilotica are noted for strong coppicing, while Quercus incana can also coppice but usually produces fewer and weaker…
Correct answer: Both (a) & (b)- A. Seed
- B. Vegetative
- C. Both (a) & (b)
- D. None of these
Explanation: Forest regeneration occurs either sexually from seed or asexually through vegetative means such as coppicing, root suckers, layering, or…

Correct answer: All of the above- A. New
- B. Both (a) & (b)
- C. Young
- D. None of these
Explanation: Regeneration replaces a mature or over-mature stand with a new generation, which is necessarily a young stand at establishment.
