The bioecological characteristics of tree plantations of some reclaimed coal dumps in Donbass are given. 26 species of woody plants have been recorded in the four studied coal mine dumps. The planting of forest crops made it possible to accelerate succession in landfill sites remote from the sources of seed deposition of woody and shrubby plants. With increasing age of plant communities, there is a deepening of the process of sylvatization, which is characterized by a complication of the structure of phytocenoses. In relation to the humidification regime, the plants are distributed in a heterogeneous way. Under the forest canopy and in the shrub thickets on the edges, mesophytes (fresh type of regime) predominate – 60–80 %. In relation to sunlight, when moving from tree-lined slopes to open plateaus, the leading role from sciophytes passes to heliophytes. In relation to the fertility of embryozems of all edges, mesotrophs predominate (60–80 %).
