This extension note summarizes a project that examined which ecological variables can be used to modify the Site Index - Biogeoclimatic Ecosystem Classification (SIBEC) model (BCMFR 2008) to provide more accurate estimates of site index. The data also provide the opportunity to compare SIBEC site index estimates based on two different methods of obtaining site index: through stem analysis and by estimating site index from a height-age model.
