Along with shelterwood and seed tree harvests, it is used by foresters to create certain types of forest ecosystems and to promote select species that require an abundance of sunlight or grow in large, even-age stands. Clearcutting is a forestry practice that mimics the stand initiation stage of forest succession after a natural disturbance such as stand replacing fire or windthrow, and is successful for regeneration of fast growing, sun tolerant tree species and wildlife species that readily regenerate in post-stand replacing sites. Logging companies and forest-worker unions in some countries support the practice for scientific, safety and economic reasons, while detractors consider it a form of deforestation that destroys natural habitats and contributes to climate change. Environmentalists, traditional owners, local residents and others have regularly campaigned against clearcutting, including through the use of blockades and nonviolent direct action.

Clearcutting is the most economically efficient method of logging. It also may create detrimental side effects, such as the loss of topsoil, the costs of which are intensely debated by economic, environmental and other interests. In addition to the purpose of harvesting wood, clearcutting is used to create land for farming. Ultimately, the effects of clearcutting on the land will depend on how well or poorly the forest is managed, and whether it is converted to non-forest land uses after clearcuts.
