Explanation: 

Detailed explanation-1: -Thinning increases the size of individual trees through redistribution and concentration of a site’s growth potential on fewer stems (Shepard 1973).

Detailed explanation-2: -Thinning has been defined as a felling made in an immature crop or stand so as primarily to accelerate diameter increment but also, by suitable selection, to improve the average form of the trees that remain.

Detailed explanation-3: -Forest thinning: Partial removal of trees is used for a variety of commercial and non-commercial purposes, including reducing competition among closely spaced stems in young stands to accelerate growth of remaining trees and reduce flammable vegetation (“fuels”).

Detailed explanation-4: -Thinning creates openings in the forest canopy allowing sunlight to reach the understory, which stimulate growth of more grasses, forbs, and shrubs. The greater abundance of native plants species closely resembles historical forest conditions.
