Summary:Based on stem analyses, national site-index equations and height-growth equations for white spruce (Picea glauca (Moench) Voss) were developed covering an area from the Yukon to Newfoundland. The objective was to construct a single set of curves for each relationship by combining all regions, instead of separate curves for individual provinces or regions. The results of these tests indicated that the objective could be reached without any significant loss of accuracy. In developing the equations a modified form of the Chapman-Richards function was employed, and results are presented in tabular and graphical forms.
