DescriptionThe usefulness of stand density index (SDI) has been limited by lack of a way to partition its nonlinear expression into additive components to describe the relative stocking of a stand by species or quality classes. In this paper, a linear equation is derived to permit such a partition. A closely related expression for grand fir stocking is given that retains the merits of SDI, but is more nearly proportional to growth of individual trees within a stand. Hence, the partitioning of stocking into components will be more meaningful to the forest manager with this revised form.
