Revision as of 01:54, 19 February 2013

The following outline is provided as an overview of and guide to forestry:

Forestry – the art and science of managing forests, tree plantations, and related natural resources. Forest ecosystems have come to be seen as the most important component of the biosphere,[1] and forestry has emerged as a vital field of science, natural resource management, applied art, and technology. The main goal of forestry is to create and implement socio-environmental systems that allow forests to continue a sustainable continuation of environmental supplies and services. The challenge of forestry is to create systems that are socially accepted while sustaining the resource and any other resources that might be affected.[2]

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
General Forested Biomes
Boreal
Taiga
Temperate
Coniferous Broadleaf and mixed Mediterranean
Tropical/Subtropical
Coniferous Moist broadleaf Dry broadleaf
Wetlands
Mangroves Bogs Swamps
Other
Urban Riparian

  • Selection – harvesting of selected trees in a stand, removing either merchantable timber or to favor the growth of desirable individuals (a thinning)
  • Shelterwood – removal of merchantable trees in succession, establishing a multiaged stand
  • Variable retention – removal of trees of varying density across a landscape, in order to retain structural diversity
  • Other
  • Salvage logging – harvesting of trees killed by natural disturbances in order to maximize economic returns that would otherwise be lost
  • Sanitation harvest – removal of individual trees affected by a pathogen in order to diminish the possibility the entire stand being affected

  • Flood control – addresses forests ecological role in natural regulation of rainfall
  • Forest dieback – where trees on the periphery of a stand are killed by acid rain or parasites
  • Forest fragmentation – occurring when forests are cut down in a manner that leaves relatively small, isolated patches of forest, resulting in high amounts of edges and subsequent loss in wildlife habitat and biodiversity
  • Forest transition – shift from a period of net forest area loss (deforestation) to a period of net forest area gain (afforestation) for a given region or country
  • High grading – type of selective logging that removes the highest timber quality trees, resulting in poor genetic stock for subsequent generations

  • Basal area – defines the area of a given section of land that is occupied by the cross-section of tree trunks and stems at their base
  • Tree taper – the degree to which a tree's stem or bole decreases in diameter as a function of height above ground
  • Girard form class – an expression of tree taper calculated as the ratio of diameter inside the bark at 16 feet above ground to the to that outside bark at DBH, primary expression of tree form used in the United States
  • Quadratic mean diameter – diameter of the tree that coordinates to the stand's basal area
  • Leaf Area Index – the ratio of total upper leaf surface of the forest canopy divided by the surface area of the land on which the vegetation grows
  • Tools
  • Biltmore stick – utilizes ocular trigonometry to quickly measure diameter and height

  • Line plot survey – plots taken at a regular predetermined distance along the traverse path
  • Tools
  • Pacing – quick method used to survey in the field, requiring calibration of one's "paces" (pair of footsteps) to a known distance (oftentimes a chain)
  • Hand compass – a compact magnetic compass with a sighting device used to determine the location of plots for a given bearing
  • Wedge prism – optical instrument typically made of glass ground at slight angles to refract light passing through it from the smaller width side of the prism to the thicker width side of the prism, calibrated to a desired plot size (basal area factor)

  • GPS – global satellite navigation systems used to determine the position of oneself and plots
  • GIS – an information system capable of integrating, storing, analyzing, and displaying forest geographic information collected in the field

Timber volume determination

  • Site index – a species specific measure of site productivity and management options, reported as the height of dominant and co-dominant trees (site trees)in a stand at a base age such as 25, 50 and 100 years
    An increment borer with common drinking straws, a cost-effective manner often used to hold derived cores.

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

  • 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
    The boom of a cut-to-length harvester with attached chainsaw cutting Pinus sylvestris in Finland.
  • 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
  • Log driving – transportation of individual logs on a waterway to a mill or port downstream
  • Timber rafting – transportation downstream of multiple logs bundled together into a raft, considered less dangerous than log driving

Harvesting tools

  • Timber felling
  • Hand
