In forestry, what does reforestation refer to?

Reforestation specifically refers to the act of planting trees in areas that have been deforested or degraded, with the aim of restoring forest cover. This process is crucial for environmental sustainability as it helps combat soil erosion, improve air quality, and restore habitats for wildlife. When forests are removed due to activities such as logging or land conversion for agriculture, reforestation serves as a way to replenish those lost resources and promote ecological balance.

While other choices touch on various aspects of forestry, they do not capture the essence of reforestation. Clearing land involves removing trees and vegetation, which contrasts with the goal of reforestation. Protecting existing forests pertains to conservation efforts and does not involve the active restoration of deforested areas. The removal of mature trees for timber relates to forestry practices that do not contribute to reforestation efforts, emphasizing the distinction between sustainable practices and those that lead to deforestation. Therefore, the emphasis on planting trees in deforested regions distinctly defines reforestation.
