Lemoine s growth and yield model has been successfully utilized to predict future timber resources from existing data collected in two successive surveys 1977 and 1988 conducted by the National Forest Inventory NFI . Lemoine s model was calibrated by analysing the error in estimation of stand features between the NFI plots and experimental plots originally used to built Lemoine s model. The proposed corrected term is based on the best linear unbiased predictor of the error. The calibrated model exhibited a better accuracy than the original model version. We suggest that coupling the calibrated Lemoine s model with NFI data is a useful method for predicting timber resources at a regional level. wood resource national forest inventory growth model model calibration maritime pine Résumé - Prediction des ressources futures en bois à partir des données d inventaire forestier national.
