Thirty-eight Sitka spruce stem analysis plots in the Queen Charlotte Islands were sampled and the height growth of the top height trees was reconstructed. A variable growth intercept model was developed for Sitka spruce from these data. This model (or a table) will be used to estimate site index for silviculture planning and other applications. Further research areas are identified that could improve the model.

Keywords: Variable Growth Intercept Model, Sitka Spruce.
