Explanation: A clone consists of genetically identical individuals produced vegetatively from one parent plant.

• A. If it is achieved naturally without involvement of man effort
• B. If it is achieved through the involvement of human efforts
• C. If it is achieved by mechanically
• D. None of these

Explanation: Artificial regeneration is established through deliberate human intervention, such as sowing seed, planting seedlings, or using cuttings.

• A. Supplementing natural regeneration
• B. Replacing natural regeneration
• C. Afforestation
• D. Introduction of valuable exotics
• E. All of the above

Explanation: Artificial regeneration may supplement or replace inadequate natural regeneration, establish new forests, and introduce valuable exotic…

• A. None of these
• B. Rotation of crops
• C. Both (a) & (b)
• D. Replacement of one crop by the other

Explanation: Regeneration means establishing a new crop to replace the previous forest crop after removal or maturity.

• A. If it is achieved naturally without involvement of man effort
• B. If it is achieved by mechanically
• C. Both (a) & (b)
• D. None of these

Explanation: Natural regeneration is the establishment of a new crop from natural seedfall, coppice, or other natural processes without deliberate…

• 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…

• 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…

• 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.

• 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…

• 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…

• 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.

• 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…

• 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.

• 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…

• 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.

• 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.

• 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…

• 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…

• 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…

• 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.
