Résumé : It should be stressed that there are very few comprehensive documents on the results of enrichment planting ln Tropical Forests. This essential fact conveys the general failure of these techniques as well as the researchers' disappointment and loss of interest. As was mentioned above, these failures can be accounted for by their need for financial, material and human investments which make them inapplicable to extensive areas and disproportionate to the low increase in productivity of the forests treated. Finally, the disappearance in some countries of large areas of treated forest, In favour of agricultural clearing, limits the opportunities for the use of extensive techniques of forest production. Highly productive plantations may be, in this case, more easily justified in socio-economic and space utilization terms in relation to the agricultural need for land Nevertheless, for ecological reasons and to preserve the genetic heritage, significant forest areas will have to be kept, part of which may be the object of extensive treatment within the framework of a plan. In the current state of knowledge, the various enrichment planting techniques cannot be adopted, at least for the dense moist forest, as they compete with simpler silvicultural techniques, such as thinning of natural stands, in favour of noble species and at the expense of commercially secondary species.
