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.
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.

The Bowron clearcut or the Bowron River clearcut was a forest clearcut near the Bowron River in British Columbia, Canada. It was once considered the largest clearcut in the world. A large timber salvage operation took place in the 1980s in response to a spruce beetle infestation. 15 million cubic meters of wood were harvested. [1]
clear-cutting involves removal of all trees from a tract of land within a 20-acre area followed by replanting if the new ingrowth of seedlings does not meet stocking levels outlined by the Forest Practice Rules. This can result in disturbances in the Sierra Nevada environment by creating patches of densely packed, single-species, same-aged ...
The main aim of this process is to clear areas of forest, woodland or scrub in order to use the soil for another purpose, such as pasture land, arable farming, human settlement or the construction of roads or railways. Many of the world's most prominent forests have suffered significant levels of clearing in recent years, including the Amazon.

Various cutting techniques are used, from cutting single trees to clearcutting blocks up to 25 acres (100,000 m 2) in size. Regeneration cuts (clear-cuts or other treatments designed to start a new timber stand) occur on approximately 1,300 acres (5.3 km 2) yearly out of the more than 909,000 acres (3,680 km 2) forest total.
