The simulation model PLANT-PC was developed to aid forest managers in Ontario with their forest renewal problems. The model treats the regeneration process as three separate but interdependent phases of stock production, stock storage, and plantation establishment. During each phase, growth and/or survival of seedlings are simulated according to empirical submodels reflecting the effects of various biological factors as well as management options. The model was calibrated for black spruce, white spruce, and jack pine plantations from the Nipigon, Geraldton, Hearst, Kapuskasing, Timmins, and Wawa districts of Ontario. Application of the model is demonstrated by presenting a detailed example. A simple procedure for calibrating the model to account for local or regional conditions is also provided.
