Résumé : When it comes to improving the woody vegetation cover of a degraded site, the three traditional methods usually considered are: artificial or natural seed germination, plantation establishment, or the pruning of existing trees so as to encourage sprouting. However, there is a fourth alternative, which has not yet been well investigated and to which attention needs to be drawn. In some regions (particularly semi-arid, temperate) before the total disappearance of existing trees, layering and moreover, suckering, allow for the economical propagation of woody plants, particularly benefitting rural people. The present partial study exposes data, in relation to temperate regions, which is selfexplanatory. However, it could be difficult to convince people working in semi-arid regions to use these methods because of the habits which die hard. The amount of work done on Natural Vegetative Propagation study is incomplete, if not insignificant, with regard to some countries and regions. When compared with sexual propagation, the socio-economic advantages of vegetative propagation are very important. The authors conclude with the necessity to record the traditional knowledge on the natural layering and suckering phenomena and to start case studies on pilot local indigenous species which show this ability.
