Sanitation Harvest
In forestry and silviculture, a sanitation harvest or sanitation cutting is a harvest of trees for the purpose of removing insects or diseases from a stand of trees. Sanitation harvesting is used to prevent the diseases or pests from spreading to other nearby trees. It is a form of intermediate management and is used in order to improve an already existing stand of trees. Sanitation cutting is done when legally required, for example to prevent bark beetle outbreaks. Or, when economic considerations about preventing potential loss or future losses due to inaction may occur.

Forestry
Forestry is the science and craft of creating, managing, planting, using, conserving and repairing forests, woodlands, and associated resources for human and environmental benefits. Forestry is practiced in plantations and natural stands. The science of forestry has elements that belong to the biological, physical, social, political and managerial sciences. Forest management play essential role of creation and modification of habitats and affect ecosystem services provisioning. Modern forestry generally embraces a broad range of concerns, in what is known as multiple-use management, including: the provision of timber, fuel wood, wildlife habitat, natural water quality management, recreation, landscape and community protection, employment, aesthetically appealing landscapes, biodiversity management, watershed management, erosion control, and preserving forests as " sinks" for atmospheric carbon dioxide. Forest ecosystems have come to be seen as the most important componen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silviculture
Silviculture is the practice of controlling the growth, composition/structure, and quality of forests to meet values and needs, specifically timber production. The name comes from the Latin ('forest') and ('growing'). The study of forests and woods is termed ''silvology''. Silviculture also focuses on making sure that the treatment(s) of forest stands are used to conserve and improve their productivity. Generally, silviculture is the science and art of growing and cultivating forest crops, based on a knowledge of silvics (the study of the life-history and general characteristics of forest trees and stands, with particular reference to local/regional factors). The focus of silviculture is the control, establishment and management of forest stands. The distinction between forestry and silviculture is that silviculture is applied at the stand-level, while forestry is a broader concept. Adaptive management is common in silviculture, while forestry can include natural/conserved land ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stand Level Modelling
A forest stand is a contiguous community of trees sufficiently uniform in composition, structure, age, size, class, distribution, spatial arrangement, site quality, condition, or location to distinguish it from adjacent communities. A forest is a "collection of stands" also utilizing the practices of forestry. Stand level modelling is a type of modelling in the forest sciences in which the main unit is a forested stand. Stand description A forest stand is commonly described as in 10ths or 10%s. Thus a ratio could be given of: 3 Ponderosa pines, 2 mangrove trees, 5 silver spruces. If there was a mixed stand that stand mix could be described as mixed up to 10%, mixed 10–40% and a mixed stand over that amount. The form of mixing of the tree types is commonly given as: * individuals – when there are a few unconnected trees of a type. * troop – up to 5 trees connected of one type. * group – when there are more than 5 trees, but they are shorter than a harvestable tree. * ...

Forest Pathology
Forest pathology is the research of both Biotic stress, biotic and Abiotic stress, abiotic maladies affecting the health of a forest ecosystem, primarily Fungal infection in plants, fungal pathogens and their insect vectors. It is a subfield of forestry and plant pathology. Forest pathology is part of the broader approach of forest protection. Insects, diseases and severe weather events damaged about 40 million ha of forests in 2015, mainly in the temperate and boreal domains. Abiotic factors There are a number of Abiotic component, abiotic factors which affect the health of a forest, such as moisture issues like drought, winter-drying, Waterlogging (agriculture), waterlogging resulting from over-abundance or lack of precipitation (meteorology), precipitation such as hail, snow, rain. Wind is also an important abiotic factor as windthrow (the uprooting or breaking of trees due to high winds) causes an obvious and direct loss of stability to a forest or its trees. Often, abio ...

Salvage Logging
Salvage logging is the practice of logging trees in forest areas that have been damaged by wildfire, flood, severe wind, disease, insect infestation, or other natural disturbance in order to recover economic value that would otherwise be lost. Although the primary motivation of salvage logging is economic, it has also been suggested that salvage logging may reduce erosion, reduce intensity of future wildfires, and slow buildup of pest insects. However, there is little evidence to support such claims, and most evidence supports the view that salvage logging is harmful to forest health and function. As with other logging operations, the harvesting may be either by selection, thinning or clearcutting, and a regeneration plan may be put in place after the logging. Salvage logging may include removal of remaining live trees in predominantly dead stands. Examples One highly publicized instance of salvage logging followed the Biscuit Fire in Oregon and California in 2002. After the fire, ...
