OBJECTIVE FORESTRY

Detailed explanation-1: -Removal of old trees is beneficial for forest health because they are less immune to pathogens and diseases. Besides, clear-cuts allow more sunlight for younger trees that do not tolerate shade. As a result, saplings grow in even-aged stands.

Detailed explanation-2: -The loss of adequate tree canopy cover exposes the land to increased sunlight, making it hotter and drier. Hotter and drier air from clearcuts can raise temperatures and lessen humidity in adjacent forest areas as well, creating a significant fire hazard.

Detailed explanation-3: -Forests are often managed in an even-aged or an uneven-aged system. An even-aged system is one where the dominant trees in the forest are all about the same age. An uneven-aged system is one where there is a greater diversity of tree age classes in the forest.

Detailed explanation-4: -A clearcut is an area of forestland where most of the standing trees are logged at the same time and a few trees remain post-harvest. Forested buffers are left around streams and lakes, and the area is replanted within two years of harvest.
