 According to the results of the study, we revealed that many tree species growing in dump ecotopes are able to adaptive restructuring of the original life form. It was found that representatives of the genus Populus are pioneer species in technotopes of industrial dumps in Kryvorizhzhia. We determined that structural elements of the anatomical structure of leaf plate of species of the genus Populus are characterized by a certain level of plasticity depending on ecotopic conditions. The vitality structure of Betula pendula’s populations on iron ore dumps was clarified: eight of them belong to prosperous type, and three to depressed one. According to the level of leaf fluctuating asymmetry of B. pendula, it was found that individuals of this species show different stress reactions when growing in technotopes with different quality substrates and microclimates. It was found that certain representatives of the family Rosaceae, which have life form “bush” (Cotoneaster lucidus, Padellus mahaleb and Amelanchier spicata), show better adaptive properties for existence in the conditions of iron ore dumps than some deciduous trees. Populations of herbaceous introducents (Hyssopus officinalis, Crambe pontica, Sedum rupestre) have a high capacity for self-sustainment, despite the ecological incompatibility of growth conditions on dumps with those that are characteristic within their natural range. The successful results of field experiments with using non-traditional representatives of natural and cultural flora for phytoremediation suggest the feasibility to introduce these species into vegetation cover of those dumps, the use of which has a sociological and recreational direction. As a result of improving the technology of phytoremediation of tailings, it was found that Secale cereale goes through a full cycle of life development and forms full-fledged seeds that can self-sow. Sowing of this culture contributes to the spontaneous development of vegetation on tailings.
