Scientia Silvica Extension Series, Number  19, 1999New Height Growth and Site Index Models for Pacific Silver Fir inSouthwestern British ColumbiaIntroductionPacific silver fir (fAbies amabilis (fDougl. ex Loud.) Forbes) is an important timber crop species in coastal forests of B.C. Its rangeextends from  sea-level  to  almost timberline,  and from  the  hypermaritime region  on the  west coast of Vancouver Island  to  thesubcontinental region on the leeward side of the Coast Mountains. With this relatively wide climatic amplitude, a large variabilityin the height growth pattern of Pacific silver fir can be expected, since climate is considered to be the most influential determinantof the trajectory of height over age of forest trees. This variability, however, is not reflected in the height growth curves and siteindex tables used to estimate Pacific silver fir site index, since the curves and tables were developed from low-elevation stands onVancouver Island. Consequently, when these curves and tables are applied to high-elevation or submaritime stands, we get biasedestimates of  site  index. Accurate estimates of  site  index are necessary for accurate yield  predictions.  Furthermore, they areessential for making rational decisions about whether to cut the forest in situations where potential tree growth is marginal, suchas in high-elevation forests.Study Stands and ProcedureTo account for climatic variability, the coastal forest was stratified into two continentality strata: (f1) maritime and less-maritime(fMLM) (fincluding west Vancouver Island, east Vancouver Island and the windward side of the Coastal Mountains, respectively),and (f2) submaritime and subcontinental (fSS) (fincluding the leeward side of the Coastal Mountains). Dominant, non-suppressedtrees were sampled in relatively even-aged second-growth stands across the entire elevation range on Vancouver Island and southof the line extending from Port McNeill to Lillooet. Three trees were felled and sectioned in each of 98 stem analysis plots.Average height growth curves, height-age data at 5-year intervals, and site indices were determined for every plot. We used datafrom 67 of the plots for calibration, and from 31 of the plots for testing. Since there was a negative correlation between age andsite index, the calibration range was restricted to 100 years to provide for a more balanced data set. The test data set containedtrees  up to  160 years breast height age. To obtain climate-specific curves, the  MLM and SS continentality strata were used asadditional variables in polymorphic height and site index functions, allowing different curve shapes for different site indices aswell as for the continentality strata.Results and DiscussionThe climate-specific models developed showed differences in  height growth pattern between the  continentality strata as well asbetween site index classes (fFigure 1). When tested against the independent data, these models improved estimates of height growth(fEquation 1, Figure 1) and site index (fEquation [2], Tables 1 and  Table 2), when compared to conventional polymorphic models.Application of the models is recommended in stands within the breast height age range of 15 to 160 years in southwestern BC.Height growth model  (Equation 1)bracerightbtbracerightmidbracerighttpbraceleftbtbraceleftmidbracelefttp++-+bracerightbtbracerightmidbracerighttpbraceleftbtbraceleftmidbracelefttp++-+=----GcG40GcG40GcG40GcG40G14G14GcG16G11G14GbG14G14GcG16G11G14GbG16G11G14G36G36G36G36G48G48G36G36G36G48G48G36G30G2fG30G2bSite index mode (Equation 2)() ( ) ( )() ( ) ( )G14G18G1aG1bG11G13G14G16G16---+G24G24where: H  =  top height (fm); S  =  site index (ftop height at 50 years breast height age); A  =breast height age (fyears); e = the base of ln;    ln= natural logarithm; MLM (fmaritimeand less maritime) and SS (fsubmaritime and subcontinental) = 0 and 1, respectively.Table 1.
