context_page_description: The following outline is provided as an overview of and guide to forestry:
  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. 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.
context_section_description: 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
  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
  Units of measurement
  Cord – very common measure, equivalent to 128 cubic feet (3.62 m³), corresponding to a pile of wood, bark, and air 4 feet wide by 4 feet high and 8 feet long
  Stère – invented in France, equivalent to a cubic meter of cut wood with space for air
  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
