Stocking is a quantitative measure of the area occupied by trees, usually measured in terms of well-spaced trees or basal area per hectare, relative to an optimum or desired level of density. [1] It is also used as a measure of the growth potential of a site that may be affected by vegetation in the area along with other nearby trees.
The above equation is an expression for computing the stand density index from the number of trees per acre and the diameter of the tree of average basal area. Assume that a stand with basal area of 150 square feet (14 m 2) and 400 trees per acre is measured. The dbh of the tree of average basal area D is:
Basal area is the cross-sectional area of trees at breast height (1.3m or 4.5 ft above ground). It is a common way to describe stand density. In forest management, basal area usually refers to merchantable timber and is given on a per hectare or per acre basis. If one cut down all the merchantable trees on an acre at 4.5 feet (1.4 m) off the ...
Farm Forestry is defined as 'establishment and/or management of trees or forests on agricultural landscapes for commercial, aesthetic and/or environmental reasons [1] The term 'Farm Forestry', as used in Australia, encompasses Afforestation, Agroforestry, Analog forestry, Buffer strip, Plantation, Reforestation, Riparian-zone restoration ...
Forest inventory is the systematic collection of data and forest information for assessment or analysis. An estimate of the value and possible uses of timber is an important part of the broader information required to sustain ecosystems. [1]
In forestry, normal densities are less than 0.1 plants per square meter. Not only the biomass per square meter increases with density, but also the Leaf Area Index (LAI, leaf area per ground area). The higher the Leaf Area Index, the higher the fraction of intercepted sunlight will be, but the gain in light interception and photosynthesis will ...
In this giant tree the branch volume was only 16.7% that of the trunk volume. In many trees with smaller or fewer large branches the branch volume may average as low as 5–10% of the trunk volume. [citation needed] Detailed three dimensional mapping of the trunk and major branches of trees can be done for significant specimens.
It is paid to the current owner of the land. Historically, the price was determined on a basis of the number of trees harvested, or "per stump". Currently it is dictated by more standard measurements such as cubic metres, board feet, or tons. To determine stumpage, any stand that will be harvested by the firm is first assessed and appraised ...
