- A. Uniform system
- B. Irregular system
- C. Group system
- D. Strip system
Explanation: The group system regenerates the stand through scattered gaps or groups, with each gap producing a relatively even-aged young crop.
Correct answer: Group system- A. All of the above
- B. The character of the crops produced by such system
- C. Distribution of the age-classes over the area of the forest
- D. The methods adopted for the regeneration of the crop
Explanation: A silvicultural system includes the regeneration method, the form or character of the resulting crop, and the distribution of age classes…
Correct answer: All of the above- A. Both (a) & (b)
- B. System of successive regeneration fellings
- C. Clear felling system
- D. None of these
Explanation: Both clear felling and successive regeneration felling can concentrate felling and regeneration on a portion of the forest at a given…
Correct answer: Both (a) & (b)- A. Rearing of silk worm
- B. It is the process by which the crops constituting a forest are tended, removed and replaced by new crops, resulting in the production on woods of a distinctive form
- C. It is a kind of upland watersheds
- D. None of these
Explanation: A silvicultural system governs how a forest crop is established, tended, harvested and replaced, producing a characteristic type of…
Correct answer: It is the process by which the crops constituting a forest are tended, removed and replaced by new crops, resulting in the production on woods of a distinctive form- A. Removal of the natural vegetation cover
- B. Cultivation of land by crops which expose the soil to direct rain impact and runoff water
- C. Both (a) & (b)
- D. None of these
Explanation: Accelerated erosion results when human activities remove protective vegetation or leave soil exposed to raindrop impact and runoff.
Correct answer: Both (a) & (b)- A. Amount of rainfall
- B. Slope length
- C. Slope gradient
- D. Soil erodibility
- E. All of the above
Explanation: Erosion depends on rainfall erosivity, slope length and steepness, and the soil’s resistance to detachment, called erodibility.
Correct answer: All of the above- A. Normal or geological
- B. Both (a) & (b)
- C. Accelerated
- D. None of these
Explanation: Normal or geological erosion occurs naturally and slowly, whereas accelerated erosion is increased by disturbance, especially human…
