Question

Read the following statements and choose the correct answer about silvicultural system/s adopted for the management of Shorea robusta:
Statement (I): Under clear felling system, a rotation age is fixed and the entire area clear felled and the crop is of uniform age.
Statement (II): Selection system is adopted for areas which are badly eroded and where regeneration is problem and regeneration is obtained by natural means, which may be supplemented by planting.
Statement (III): In coppice with standards system, a few standards are retained and the other trees above the exploitable diameter are clear felled and regeneration is obtained by means of coppice.
Choose the correct answer from the options given below:

• A. Only statements (I) and (II) are correct and statement (III) is incorrect
• B. Only statement (II) and (III) are correct and statement (I) is incorrect
• C. All the three statements (I), (II) and (III) are correct
• D. All the three statements (I), (II) and (III) are incorrect

Hint:

In Coppice with Standards, the main harvest is of the coppice crop (understory), while standards are selected and retained for biological and structural purposes, not cleared simply based on exploitable diameter.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Silvicultural systems dictate how a forest stand is harvested, regenerated, and structured over time. These include clear felling, selection systems, and coppice systems.

Step 2: Detailed Explanation:
- Statement (I) is correct. Clear felling involves harvesting the entire crop in a single operation at a fixed rotation age, followed by artificial or natural regeneration, creating a new even-aged (uniform) stand.
- Statement (II) is correct. The selection system is a conservation-oriented uneven-aged system where only mature or damaged trees are selectively removed. It is ideal for ecologically sensitive, steep, or eroded areas where clear felling would cause severe soil degradation, and it relies heavily on natural regeneration supplemented by planting.
- Statement (III) is incorrect. In the "coppice-with-standards" system, the understory crop is cut to generate vegetative coppice, while a pre-determined number of individual trees (standards) are selected and retained for multiple rotations to produce larger timber and seeds. The trees are not cleared based on "exploitable diameter" (which is a feature of selection systems); rather, the lower canopy is systematically cut back to allow coppice shoots to grow.

Step 3: Final Answer:
Only statements (I) and (II) are correct, making Option A the correct choice.
