Potential site productivity (site index) functions have generally been developed from data where stands are 20 years of age or more. A segmented regression technique was applied to existing site index curves to aid in predicting heights at ages less than 20 years. This approach is illustrated with young red pine data from the Lake States and shows improvement in height prediction at young ages. With this approach, existing site curves for older trees are not changed and can continue to be used without altering their results for older stands. North. J. Appl. For. 8(2):59-63
