Introduction : Fagacées is a growth model that has been developed for pure Oak or Beech stand management in even-aged high forests and coppice with standards forests. It has been calibrated for the plain forests of northern France. * Objectives : This paper presents all the characteristics of this model: general structure, equations, and parameters. It can be classified as a distance-independent tree-centered model. Its main originality is that tree growth is organised according to a top-down organisation. * Result : At first, the growth is computed at the stand level. Then it is allocated between the individual trees. The paper presents and discusses successively these two parts. In addition, the model delivers the stem profile of each tree: rings and compartments within the stem. Some other additional modelling that have been defined for batch mode purposes are also briefly presented.
