A Method of Constructing Site-Index Curves from Stem Analyses

Site-index curves were constructed from stem-analyses data with the help of linear regressions derived for relationships between site index (total height at BH age of 50 years, the independent variable) and total heights attained at the end of the previous nine 5-year periods. The method was tested for white spruce, black spruce, lodgepole pine and jack pine.
