Abstract: The results of studies of the condition of reforestation stands and canopies of artificial and natural origin growing on dumps of coal mines of Mezhdurechensk are presented. The assessment of a possibility to restore taiga species composition of stand on the pit dumps is carried out. It is established that the closed cultures of a common pine forest created according to classical forest schemes, with density of landing over 4 thousand copies/hectare, impede the settlement of species of a zone arboriflora and own renewal. Creation of the mixed forest cultures creates prerequisites for formation of multispecific plantings, and the spaced planting of a pine promotes the active settlement of a Siberian cedar, Siberian firs, aspens and the underbrush species. Optimum conditions for recovery successions on taiga species develop in the middle-close plantings of birch where the developed reforestation canopy consisting of the uneven-age subgrowth of taiga species and an underbrush is formed. On elevated ele-ments of a dump-site relief, the seeding by forest types occurs at the expense of own seeds. In the xeromorphic conditions of slope surfaces, intrazonal succession is noted, in which pine stands play an important role, thanks to which the formation of renewable mono-type communities is possible in the future. Based on the conclusions of this study, the schemes of forest reclamation can be proposed aimed at formation of steady self-sustaining forest ecosystems in the sub-zone of taiga.
