Coppice forests are degraded, low output forests. They fulfill poorly their environmental, social and productive functions, and conversion into high forests will improve them. Quercus frainetto (Ten.) is the most important oak in Greece, representing 13\,% of the standing volume. The objective of this chapter is to introduce the new modeling technology in Greece and to adapt the Austrian individual-tree, distance-dependent simulator MOSES for modeling the development of Qu. frainetto. The data for this study came from 25 permanent experimental plots across Greece. Four models driving the growth of Qu. frainetto were considered: diameter and height increment, crown recession and mortality models. Non-linear regression methodology was used for parameter estimation. The development of diameter and height increment models was based on the assumption that the potential increment for a given tree is reduced by a function of the crown ratio as an allometric multiplier representing the past growing conditions and an overstocking multiplier representing the current competition conditions. The crown model predicts future crown length depending on tree height, crown ratio and the competition index. Finally, in the mortality model, trees are stated to be either alive or dead, and the respective predicted probability of mortality in the next growing period is bound between 0 and 1. Therefore, a logistic equation was fitted using the crown ratio, competition index and diameter as independent variables. The simulator DRYMOS, a derivative software program of the Austrian simulator MOSES, incorporates the developed models for Qu. frainetto in a user-friendly interface. After the selection of a stand, the user has the opportunity to project the stand in two- or three-dimensional form, apply silvicultural treatments and produce results in tabular or graphical form. Qu. frainetto stands can be efficiently modelled with distance-dependent and site-potential approaches. Tree size, growth and competition are the main driving variables in predicting growth and development of Qu. frainetto. The simulator DRYMOS is capable of describing the evolution and future stand dynamics of Qu. frainetto under different stand densities and silvicultural scenarios.
