Trees that have been felled.
A patch cut is a forestry or forest regeneration practice that involves the removal of all trees in a block or patch less than 2.5 acres (1 hectare) of a forest system. Patch cutting is a variation of the larger, more controversial, clearcut practice with several distinct advantages. A patch cut creates less visual and environmental impact in forested areas, is easier to manage, and has several regeneration benefits common to other less flexible cutting practices. Patch cuts are usually carried out in stands of trees of equal age and, although they usually form a group of harvested areas, they are managed individually as separate openings or cuts.
Forestry is a forest industry practice focused on renewing harvested forest resources. The basic principles involve controlling tree densities, growth rates and overall stand health, as well as the composition of tree stocks in any given area. An essential part of forestry from a forest standpoint is how tree stocks are harvested.
Clear cutting is one of the silvicultural practices that has become a subject of debate due to the large deforestation involved. It involves the non-selective felling of all, or at least most, trees in a forested area. This has obvious effects on local ecosystems because of the mass destruction of natural habitats, in addition to the inescapable aesthetic effect of large-scale landscape denudation. Patch cutting, while technically a variation of clearcutting, is a much less invasive method of harvesting wood with very low latency for forests as a whole.
Patch cutting involves the complete removal of all trees from an area of forest that are 1 hectare or older. Not only does this create less visual disturbance, it can also preserve the habitat as a whole. After the trees have been cut down, the rejuvenation process can be managed using natural or artificial methods such as seeding or planting new trees. A patch cut also allows the regeneration process to focus on shade-tolerant tree species, which is usually only possible with selective cutting systems. However, patch cuts are easier to clean and rejuvenate than selective cuts, due to the complete removal of trees, which creates new growth of equal ages.
Individual patch areas will normally be part of a series of clean areas at the same time. Each of them is treated, however, as an individual cut or deforestation, thus enabling a better overall control of different forest areas. Patch harvesting has the added benefit of having minimal impact on the overall biodiversity of any forest area. As a logging practice, it also creates less potential for soil erosion and flooding.
