Natural regeneration of forests is primarily dependent on what?

Natural regeneration of forests occurs when trees and other vegetation reproduce without human intervention, relying mainly on the natural processes of seed dispersal or sprouting. Seeds, whether from existing trees or surrounding vegetation, play a crucial role in developing new plants. This process can include seeds falling to the ground and germinating or sprouts developing from the roots or stumps of established trees.

Natural regeneration is often favored in forest management because it is a cost-effective and environmentally sustainable method for restoring and maintaining forest ecosystems. In contrast, the other options involve direct human action, such as actively planting seedlings or transplanting trees, which do not align with the concept of natural regeneration. Harvesting old growth relates more to forest management practices rather than the regeneration process itself, making natural seed dispersal the primary mechanism for forest regeneration.
