Explanation:
Detailed explanation-1: -Shelterwood cutting is the progression of forest cuttings leading to the establishment of a new generation of seedlings of a particular species or group of species without planting. This silvicultural system is normally implemented in forests that are considered mature, often after several thinnings.
Detailed explanation-2: -There are three major groups of timber harvest practices; clearcutting, shelterwood and selection systems.
Detailed explanation-3: -Shelterwood harvesting is an even-aged system used to establish and develop desirable natural regeneration. By removing a mature stand in two to three cuts over five to 20 years, more sunlight reaches the forest floor to stimulate seedling development.
