Cutting down only mature trees allows more resources to be available for the younger growing trees and extends the life of the forest.
Explanation:
- Older an taller trees grow to a height and forms a canopy over the forest floor.
- This cuts the maximum amount of sunlight from reaching the under growths.
- Thus the shorter and younger trees lie in shade and cannot grow properly due to lack of sunlight.
- On the other hand the trees could penetrate deeper into the soil consuming up a lot of nutrient and the competition for resources becomes maximum.
- When taller and older trees are cut, the canopy is removed and sunlight couldl penetrate to the forest floor and the stress on soil is also reduced , thus allows the growth of younger trees which in turn extends the life of the forest.
