Resumo: The initialization of a growth and yield model is most of the times based on data coming from a forest inventory. However, it is usual that the user carries on a simplified inventory in which not all the variables needed for the initialization of the model are gathered. The additional data, needed for model initialization, will be obtained within the model through simulation of the required tree and stand variables based on the soil and climate characteristics as well as on the values of the tree or stand variables directly obtained in the inventory. The present thesis considers several themes related to the initialization of a growth and yield model, some of them related to the methodologies to be used in the forest inventory itself and others with the simulation of the variables not measured directly during this inventory. The system developed, applicable to any individual tree model for cork oak stands, but specifically developed for the SUBER model, includes: methodologies for the realization of forest inventories for the characterization of the cork and of the trees; a system for the prediction of the evolution of cork caliber over time, essential for the simulation of the cork growth index distribution; methodology for the modeling of such distribution, which allows for the simulation of cork caliber for the trees in which this variable has not been measured.
