Stocking (forestry)

From Wikipedia, the free encyclopedia

In forestry, 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] A desirable level of stocking is often considered that which maximizes timber production, or other management objectives.

Stocking can be expressed in either absolute or relative terms. Absolute terms include the basal area or trees per acre. Relative terms measure the density against a reference level, which is determined by dominant tree species, the plant community, and site index.[2]

Stand density is not the same as stocking. See stand density index for the difference.
