Abstract
Equations that predict site index for western hemlock (Tsuga heterophylla (Raf.) Sarg.) from the site index of western redcedar (Thuja plicata Donn ex D. Don) (or vice versa) are needed to make good forest management decisions in the Pacific North West. Site index data for hemlock and redcedar were collected from sample plots located in two major ecological subzones in southern coastal British Columbia. Geometric mean regression was used to estimate the parameters of a linear model relating the site indices of hemlock and redcedar. The correlation between the site indices was high, indicating a good fit to the linear model. In general, the site index of hemlock is higher than the site index of redcedar, indicating that hemlock is more productive than redcedar on a given site. A validation procedure showed that one set of conversion equations was adequate for both ecological subzones. The conversion equations can be applied in mixed species stands or in stand conversion situations, although caution is required for both applications
