What is the main objective of thinning in forestry?

The main objective of thinning in forestry is to promote growth by reducing competition among trees. Thinning involves selectively removing some trees within a stand, which helps the remaining trees access more sunlight, water, and nutrients. This practice reduces crowding and allows healthier, more robust trees to grow, ultimately improving the overall stand's health and economic value. It can lead to better quality timber and enhanced forest resilience against pests and diseases.

While clearing all trees in an area is more akin to clear-cutting, which is not a selective process, only harvesting dead trees is not the primary purpose of thinning, as it focuses on enhancing the growth of live trees instead. Establishing a new forest would generally involve different practices such as planting and is not the goal of thinning, which focuses on managing existing tree populations.
