Forestry – science and craft of creating, managing, using, conserving, and repairing forests and associated resources to meet desired goals, needs, and values for human and environment benefits.[1] Forestry is practiced in plantations and natural stands. Forestry accommodates a broad range of concerns, through what is known as multiple-use management, striving for sustainability in 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.

Focus of forestry
  • Tree – organism, whose species, age, vitality, growth, health, and size, are considered individually or more often, as part of a whole;
  • Forest – defined as either a geographic area or delineated by the general composition of individuals;
  • Biome – ecologically defined by its forest structure, leaf types, tree spacing, and climate

Branches of forestry
  • Agroforestry – integration of forests into agricultural systems in order to optimize the production and positive effects within the system and minimize negative side effects of farming
  • Boreal forestry – analyzes the particular challenges of forestry in the world's boreal regions
  • Close to nature forestry – theory and practice that takes the forest as an ecosystem and manages it as such. It is based on reduced human intervention, that should be directed to accelerate the processes that nature would do by itself more slowly.
  • Dendrology – involves the study and identification of economically useful tree species
  • Energy forestry – includes specifically managing for the production of energy from biomass or biofuel derived from a fast-growing species of tree or woody shrub
  • Forest ecology – studies the patterns and processes of a forest ecosystem
  • Forest economics – studies the impact of economics on forest management decisions
  • Forest hydrology – embodies the effects of changes in forest land use on the movement, distribution, and quality of water in the ecosystem
  • Forest mensuration – incorporates quantitative measurements of the forest stand to determine stand timber volume and productivity/health, and provides a basis off which management decisions can be made
  • Forest pathology – research of both biotic and abiotic maladies affecting the health of the forest or tree, primarily fungal pathogens and their insect vectors
  • Silviculture – is the art and science of controlling the establishment, growth, composition, health, and quality of forests to meet specific objectives
  • Social forestry – addresses human-forest interactions, and the importance of community-based natural resource management
  • Sustainable forestry – emphasizes forest management for long-term environmental, social, and economic sustainability
  • Tropical forestry – is particularly concerned with management and conservation of forests in the tropics
  • Urban forestry – entails the care and management of urban tree populations for the purpose of improving the urban environment
  • World forestry – examines forest conservation at a global level

Forest management

Forest management – comprises the overall administrative, economic, legal, and social aspects of forest regulation

  • Analog forestry – a management focus that seeks to establish a tree-dominated ecosystem that is similar in architectural structure and ecological function to the naturally occurring climax and sub-climax vegetation community
  • Bamboo cultivation – farming and harvesting bamboo for commercial purposes such as construction.
  • Community forestry – combination of forest conservation with rural development and poverty reduction objectives, accomplished through instating a legal framework that favors profitable and sustainable forest management
  • Ecoforestry – emphasizes practices which strive to protect and restore ecosystems
  • Hardwood timber production – process of managing stands of deciduous trees to maximize woody output
  • Tree breeding – method of genetically modifying/selecting forest stock for improved growth or vigor characteristics
  • Mycoforestry – ecological forest management system implemented to enhance forest ecosystems and plant communities through the introduction of mycorrhizal and saprotrophic fungi
  • Permaforestry – approach to the wildcrafting and harvesting of the forest biomass that uses cultivation to improve the natural harmonious systems. It is a relationship of interdependence between humans and the natural systems in which the amount of biomass available from the forest increases with the health of its natural systems.
  • Plantation forestry – industrial plantations are established to produce a high volume of wood in a short period of time. Some plantations are managed by state forestry authorities (for example, the Forestry Commission in Britain) and others by paper and wood companies (such as Weyerhaeuser, Rayonier and Plum Creek Timber in the United States, Asia Pulp & Paper in Indonesia).
  • Short rotation forestry – managing a forest that utilizes fast-growing species as a bio-based energy crop for use in power stations, alone or in combination with other fuels such as coal
  • Sustainable forest management – emphasizes practices that maintain forest biodiversity, productivity, regeneration capacity, and vitality, while continuing to fulfill relevant ecological, economic and social functions
  • Tree farm – a forest or woodland owned privately where timber crop production is a major management goal

  • Stocking – a quantitative measure of the area occupied by trees relative to an optimum or desired level of density which varies according to management purpose even on the same site
  • Stand Density Index – a measure of the stocking of a stand of trees based on the number of trees per unit area and DBH of the tree of average basal area
  • Volume table – a chart based on volume equations that uses correlations between certain aspects of a tree to estimate the standing volume
  • Stand density management diagram – model that uses current stand density to project future stand composition

  • Board foot – specialized unit of measure for lumber in North America, equivalent to the volume of a one foot length of a board one foot wide and one inch thick

Stand growth assessment
  • Increment borer – specialized tool used to extract a section of wood tissue from a living tree with relatively minor injury to the tree, used often for tree growth analysis
  • Mean annual increment (MAI) – refers to the average growth per year a tree or stand of trees has exhibited at a specific age
  • Periodic annual increment (PAI) – describes the average annual change in tree diameter between the beginning and ending of a growth period, used more often than MAI for percental growth
  • Ecological yield -the amount of wood volume in any given year whose harvesting would be considered sustainable
  • Growth and yield modelling – entails the creation of models of prospective tree growth and harvest yield for management purposes
  • Economics
  • Stumpage – the price charged by a land owner to loggers for the right to harvest standing timber on that land
  • Optimal rotation age – the age at which the harvesting of stumpage will generate the maximum revenue or economic yield

Harvesting
A cable logging setup in Germany (1988).

Logging – cutting, skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. The term is sometimes used in a narrow sense to mean moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. However, in common usage, the term may be used to indicate a range of forestry or silviculture activities...

Harvesting methods

  • Scaling – measurement of felled trees to determine the volume of merchantable wood
  • Skidding – transportation of logs from the site of felling to the landing along the ground
  • Forwarding – transportation of logs from the site of felling to the landing above the ground, usually to minimize soil disturbance but limits the size or amount of logs that can be moved at once
  • Hauling – long-distance transportation of logs from the landing to their final destination, usually with a semi-truck but occasionally with a train
  • Woodchipping – grinding of logs into chips for engineered wood, mulch, paper, or fuel
  • Cut-to-length logging (CTL) – an expensive but efficient system where trees are felled, delimbed, and bucked to scale directly at the felling site
  • Cable logging – skidding using a wire cable attached to the felled trees, most common in areas with steep topographic relief, variations include
  • Shovel logging – transport of multiple logs close to the logging road using a stationary loader, often used to minimize soil disturbance
  • Heli-logging – transport of logs from the forest to the landing via helicopter, most commonly used in inaccessible areas or to minimize impact on the soil

Forest product – any material derived from a forest for direct consumption or commercial use, such as lumber, paper, or forage for livestock. Wood is by far the dominant forest product, used for fuel (as firewood or charcoal), structural materials in the construction of buildings, or as a raw material, such as wood pulp used in the production of paper. All non-wood products derived from forest resources are called non-timber forest products.

  • Lumber (also "timber") – structural material for the construction of buildings or furniture making
  • Paper – made from wood pulp derived from the timber stock pulpwood
  • Paperboard – a thick packaging material derived from paper, cardboard is the generic term
  • Veneer – thin layers of high-quality wood, often decorative but also the primary product in plywood
  • Multilaminar veneer – like veneer, but utilizes plantation wood in accordance with the principles of sustainable forest management
  • Oriented strand board – mainly used in structural insulated panels, has largely replaced plywood
  • Fiberboard – a cheaper and denser form of plywood, used when cost is considered most important. Often used as the underlying structure in car dashboards
  • Drywall – a gypsum plaster placed inside two sheets of paper, used commonly as the finishing step in construction of interior walls and ceilings
