Question

A major program called 'silviculture' has been started to replenish the forests. Which of the following is not an advantage of this program?
A. It maintains a perfect water cycle in nature
B. It prevents soil erosion
C. Its practice does not vary with different terrains and soil types
D. It produces a large quantity of raw materials for industry

Answer 1

Hint: In order to meet diverse needs and values, silviculture is the method of regulating the growth, health, composition, and quality of forests. The term comes from the Latin word 'silvi' which, as in rising, means forest and 'culture'.

Complete answer:
Silviculture is generally the art and science of growing and managing forest crops, based on silviculture i.e. the study of the history of life and general features of forest trees and stands (with special regard to locality factors). In silviculture, adaptive management is common, where forestry can add natural and preserved land without employing stand-level management and treatment.

Regeneration is the key goal of silviculture, but recently, silviculture has been challenged by recreational use of forestland as the prime income generation from forests, due to increasing awareness of the use of forestland for recreation and leisure. The downside of uneven-aged forests is that management needs heavy equipment to enter more regularly, which can destroy residual live trees, reduce their economic value, and increase their insect and disease vulnerability. With various terrains and soil types, their practice does not vary.

Hence, option C-Its practice does not vary with different terrains and soil types is the correct answer.

Note: Benefits of silviculture are as follows:
-It increases the cover of forests that are important for wildlife protection.
-This ensures a perfect balance of water in nature.
-Since the forest cover is vast, it prevents floods.
