Scientia  Silvica Extension Series, Number  15, 1998 Height growth curves and site index tables for subalpine fir, Engelmann spruce, and lodgepole pine in the ESSF zone of BC Height growth models of coastal low- and mid-elevation Pacific silver fir, low-elevation white spruce, and low- and mid- elevation lodgepole pine have been used for predicting productivity of subalpine fir, Engelmann spruce, and lodgepole pine, respectively.  These models, however, are biased in predicting height growth of high-elevation subalpine fir, Engelmann spruce, and lodgepole pine. To improve this situation, 329 sample plots (165 for subalpine fir, 90 for Engelmann spruce, and 74 for lodgepole pine) were located throughout the Engelmann Spruce-Subalpine Fir (ESSF) zone.  Stem analysis was carried out on three dominant trees in each 0.04 ha sample plot.  For each study species, a height growth model was developed on the data from two-thirds of the sample plots using the conditioned Chapman-Richards’ function; the model was validated using the remaining one-third of the sample plots. The models developed were used to construct height growth curves and tables.  They are recommended for estimating site index of these three major timber crop species in the ESSF zone. Subalpine fir [ ]    = + − − −              where: ( )   = −     − − − ×                  where: H = top height (m); S = site index (height at 50 year breast-height age); A = breast-height age (year); e = the base of exponential func- tion; and ln = natural logarithm.
