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.
In 2020, the world had a total forest area of 4.06 billion ha, which was 31 percent of the total land area. This area is equivalent to 0.52 ha per person [2] – although forests are not distributed equally among the world's people or geographically. The tropical domain has the largest proportion of the world's forests (45 percent), followed by ...

While forests managed for wood production commonly yield between 1 and 3 cubic meters per hectare per year, plantations of fast-growing species commonly yield between 20 and 30 cubic meters or more per hectare annually; a Grand Fir plantation in Scotland has a growth rate of 34 cubic meters per hectare per year, [1] and Monterey Pine ...
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 ...
