Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Selective cutting differs from clear cutting in that selective cutting:
A
Increases surface runoff and erosion
B
Only removes a few trees
C
Takes out all the trees
D
Reduces the risk of forest fires
Explanation: 

Detailed explanation-1: -Clear-cutting is the removal of all or nearly all trees in the stand. In selective harvest logging, most trees remain. Regeneration after clear-cuts is the growth of trees of nearly the same age, which is an even-aged forest management practice.

Detailed explanation-2: -Selective logging is the removal of selected trees within a forest based on criteria such as diameter, height or species. Remaining trees are left in the stand, as opposed to clearcutting where all trees are felled. This intervention is similar to several others that involve harvesting some, but not all, trees.

Detailed explanation-3: -Selection cutting, also known as selection system, is the silvicultural practice of harvesting trees in a way that moves a forest stand towards an uneven-aged or all-aged condition, or ‘structure’.

Detailed explanation-4: -What Is Clear-Cutting? Clear-cuts are forest-felling when all or most of the trees are removed in the selected area at the same time. The method is the most commercially attractive and thus the most typical one. Commonly, trees are cut uniformly.

Detailed explanation-5: -Selection cutting is a harvesting method designed to create an uneven-aged or all-aged stand structure by harvesting single trees or small groups of trees. It is believed that this has ecological benefits, including increased carbon sequestration, as well as producing a more constant flow of marketable timber.
