Abstract
Trembling aspen (Populus tremuloides), a common hardwood species in the interior of British Columbia, Canada is becoming an increasingly important timber crop species, especially in the northeast corner of the province. Better growth and yield information for aspen is required to manage this species properly. Height-age models for estimating site height and site index are provided in this paper. One-hundred and thirty-five stem analysis plots were established in six biogeoclimatic zones. Three trees in the 0.04 ha plots were selected and stem analysed, and ecological data were collected at each plot. The stem analysis data were split into a model calibration and test data set. Two models were fit to the calibration data: a base model and an extended model that is calibrated for the six biogeoclimatic zones. Both models adequately estimate the height of trembling aspen in British Columbia. The base model was compared to two models for aspen in Alberta, which showed that there were no large differences in the height growth of aspen, except on lower productivity sites.
