JuRASEK Forestry and Game Management Research Institute Opocno Research Station Opocno Czech Republic ABSTRACT Vegetative propagation of forest tree species is of great importance not only for breeding programmes but also for the conservation of valuable populations of tree species. Important is also a possibility of improving the genetic quality of established stands. Beech is a tree species that can substantially increase the stability of forest ecosystems. Minimal information is available about the ontogenesis of rooted cuttings of beech in forest stands for the time being. In our experiments that were gradually established since 1993 we acquired the first significant results of the evaluation of health status phenological phenomena and growth of these plants. Our findings indicate that it is possible to use rooted cuttings as an element stabilising man-made forest stands including the transferred genetic quality. The evaluation of the 2nd generation rooted cuttings of beech also provided positive results. Keywords beech rooted cuttings plantings ecosystem stabilisation Autovegetative techniques of forest tree species propagation will be used on a larger scale in future. These methods may also contribute to the fast reproduction of valuable populations of tree species while their genetic identity is guaranteed and may be a full-value substitute source for forest reproduction when a sufficient quantity of good-quality seed is not available Jurasek et al. 1997 . Important is also a possibility of clone selection in relation to the anthropogenic load of forest stands and to potential climate changes. The plants produced by vegetative propagation may markedly increase the stability of forest ecosystems. In connection with vegetative methods of propagation a risk of narrowing the genetic variability of a .
