The purpose of this project was to develop growth intercept and height-age models for amabilis fir (Abies amabilis Dougl. ex Forbes) on the coast of British Columbia. Twenty-eight stem analysis plots were established on Vancouver Island. These data were combined with data from 46 previously established stem analysis plots. The stem analysis data were converted into height-breast height age data and the site index was obtained from the data. A suite of 50 growth intercept models was developed, one model for each breast height age from one to 50. A height-age model based on the Hossfeld IV function was also developed. There were minor differences between the new height-age model and the height-age model currently in use. Therefore, implementation of the new height-age models should have minimal consequences on timber supply analyses and forest management decision making. Funding for this project was provided by FIA-FSP.
