A part or parts of forest set aside to be regenerated or otherwise treated during a specified period is known as _______
Show Hint
In a standard rotation of 120 years with a period of 30 years, there will be exactly 4 periodic blocks (designated as PB-I, PB-II, PB-III, and PB-IV).
Updated On: Jul 10, 2026
- Compartment
- Felling area
- Coupe
- Periodic block
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
In forest management, particularly under the Shelterwood system, the forest is divided into administrative and silvicultural units to regulate harvesting and regeneration.
Step 2: Detailed Explanation:
- A Periodic Block (PB) is a silvicultural unit of a forest containing stands that are scheduled to be regenerated, thinned, or otherwise treated during a specific time interval (the regeneration period, typically 10 to 30 years).
- A compartment is a permanent territorial division of a forest.
- A coupe is a specific annual cutting area.
- Therefore, the division set aside for systematic treatment during a designated period is a periodic block.
Step 3: Final Answer:
The designated area is known as a periodic block.
