Clear-cutting impacts the water cycle, as trees hold water and topsoil. Clear-cutting in forests removes the trees which would otherwise have been transpiring large volumes of water and also physically damages the grasses, mosses, lichens, and ferns populating the understory.
Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period. Net change, therefore, can be positive or negative, depending on whether gains exceed losses, or vice versa.
Clear cut in the Gordon River Valley near Port Renfrew, BC. British Columbia is one of the world's largest exporters of wood fibre. [19] In 2015 it was reported that British Columbia forestry supports 145,800 jobs and 7000 businesses, with an annual revenue of 15.7 billion dollars. [19]
Clear cutting areas for even-aged timber management can also benefit many wildlife species. The abundance of coarse woody debris added to the forest floor is beneficial to salamander and snake species, while the release of understory shrubs provides an increase of berry-foraging opportunities for bear and songbirds.

Group shelterwood organizes cutting into concentric circles originating from the first cuts in the patch in the center of the circle. [3] Eventually these concentric circles meet at which point the entire stand has been cut. [5] Sometimes the first cut will simply release a patch of advanced regeneration that will serve as the center of the ...
Restoring global forests could sequester 22 times as much carbon as the world emits in a year, according to a scientific study published on Monday, making the case that trees are a key tool in ...
The forest resources of the United States remained relatively constant through the 20th century. [3] The Forest Service reported total forestation as 766,000,000 acres (3,100,000 km 2) in 2012. [4] [5] [3] A 2017 study estimated 3 percent loss of forest between 1992 and 2001. [6]
