Clearcutting, clearfelling or clearcut logging is a forestry/logging practice in which most or all trees in an area are uniformly cut down. Along with shelterwood and seed tree harvests , it is used by foresters to create certain types of forest ecosystems and to promote select species [ 1 ] that require an abundance of sunlight or grow in ...
Cutting trees with the highest value and leaving those with lower value, often diseased or malformed trees, is referred to as high grading. It is sometimes called selective logging, and confused with selection cutting, the practice of managing stands by harvesting a proportion of trees. [9] Logging usually refers to above-ground forestry logging.
Selective logging is often considered a better alternative to clear cutting. [1] Selective logging in the Brazilian Amazon Rainforest was recently shown in analyses of Landsat Enhanced Thematic Mapper Plus data at high spatial resolution to be occurring at rates of about 12,000–20,000 km 2 per year, [2] thus indicating the central role of ...
Selection cutting is often (sometimes deliberately) confused with "selective" cutting, a term synonymous with the practice of highgrading (the removal of the most economically profitable trees in a forest, often with a disregard for the future of the residual stand). Often the latter term is used by foresters or loggers to imply the former ...
“Forest management is the best way to halt environmental crime, from land-grabbing to illegal logging,” Frank Almeida, president of the National Forum, told the AP. “But there is no use in creating a project that won´t become a reality,” he said, referencing recent government actions related to exports that have generated business ...
In forestry, high grading, also sometimes referred to as selective logging, is a selective type of timber harvesting that removes the highest grade of timber (i.e. the most merchantable stems) in an area of forest. It is sometimes described by the phrase “cut the best and leave the rest”, and should not be confused with selection cutting.
Selective logging is another method used to meet the needs of both the forests and humans seeking economic resources. Selective logging is the removal of trees within a stand based on size limitations. This technique allows for forest regeneration to occur between and after the selective harvest cycles. [31]
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.
