Question

Which is the most common method of tree harvesting for an even aged forest stand?

A.clear-cutting
B.selective cutting of groups of trees
C.shelterwood cutting
D.Selective cutting of single trees

Answer 1

Clear-cutting is the most common method of tree harvesting for even-aged forest stands, but it poses significant ecological risks. Strip cutting offers a more sustainable alternative, allowing for forest regeneration. Sustainable forest management is essential for balancing economic and ecological needs.

Step-by-step explanation:

The most common method of tree harvesting for an even-aged forest stand is clear-cutting. This method involves the removal of all trees in an area, which can create large openings for new stands of a uniform age. Despite its efficiency for timber production, clear-cutting has significant ecological impacts, such as habitat destruction, soil erosion, and reduced biodiversity. It can lead to a devastated area for an extended period. Strip cutting is suggested as an alternative, which involves harvesting trees in narrow strips, leaving rows of trees standing that can aid in the recovery and replenishment of the forest.

Deforestation from clear-cutting and selective logging has increased globally, particularly in tropical regions for timber and agricultural land use, contributing to environmental and economic challenges. Sustainable management practices and regulations are vital to balance economic needs and environmental conservation, ensuring that forests can continue to provide resources and ecological services for future generations.

Answer 2

Selective cutting of groups of trees is the most common method of tree harvesting for an even aged forest stand

Step-by-step explanation:

Selection cutting is the other name given for the selective cutting method.It is also called as "selection silviculture". It is a method of cutting down the trees that are grown in the way of forest and ends up in cutting those trees that are aged and uneven or all old aged trees.

It is the process of cutting down a set of trees which can be either 3 or 5 or 10 together that are of olden age. The age of the trees can be learnt with the help of stocking models that are obtained form the old growth trees study. Using stocking models derived from the study of old growth forests. The implementation of this process is difficult but it has various economic benefits associated with it.
