Central African rain forests contain a wide diversity of tree species but logging focusses on a restricted range of valuable timber species. We assume that forest management mainly consists in the management of timber tree populations living in their natural environment. This approach is illustrated with the example of moabi, a timber species from Cameroon. For two and a half years, we measured survival, growth, fecundity and spatial distribution of every class of seedlings and trees of this species in permanent plots located in the "Réserve de Faune du Dja" and in the adjoining concession. After an introduction chapter, we study phenology and germination of moabi, seed dispersal by mammals, seedling growth in the understorey and demographic parameters of the adult population. On the basis of these values, we build a matrix model which reproduces the evolution of class sizes of moabi over a period of time. This demographic model enables on the one hand to quantify the impact of the present logging practices on tree population dynamics and on the other to assess the impact of various management scenarios designed by changing parameters such as limit diameter and rotation time. Based on ecological data, this thesis provides a quantitative decision tool for the management of natural tropical forests.
