| Abstract
| - On the basis of a national forest inventory, made in the years about 1975, the available annual yield of Norway spruce in the north east of France was evaluated by means of a growth and yield model. The main parameters of the growth model were estimated from the survey stand data to represent general field conditions, but the results from a former yield study ot Norway spruce in the same region provided the necessary site curves. A validation of the derived model with stand data not used in the estimation of the model parameters was judged successful. In this paper methodology is emphasized rather than specific results, but useful features of growth and yield for public and private forests, from 1975 to 2005, are given separately. Thus, stand volume, current annual increment, volumes from thinnings and final felling appear each decade, and allow the prediction of the evolution of forest resources and available yield.
