Research work report: 51 p., 25 sources. Research object: vegetative mobility of common sea-buckthorn (Hippophae rhamnoides L.), white poplar (Populs alba L.) and Italian or pyramidal poplar (P. italica Moench) at the iron ore dumps in Kryvyi Rih area as well possibility to use biological peculiarities of these species for dump recultivation. Research aim: using of adaptive capabilities to vegetative mobility of some stable arboreal plant species under extreme conditions of iron ore dumps in Kryvyi Rih area as method of stable reforestation at these radically changed technogenous territories. We used botanical and dendrological methods to estimate the state of tree groups of these three species at iron ore dumps in Kryvyi Rih area. Theoretical results concern with ascertaining Hippophae rhamnoides, Populs alba and P. italica adaptive capabilities to form such live-form as group-forming tree by yearly growing of stool shoots around maternal plant. Practical results: all three species grow at five investigated dumps due to natural anemochoric or zoochoric penetration. Tree groups form around maternal plant by stool shoot distribution; size of these groups consists from 5 till 500 m2 (according to maternal plant age). Under dump condtition the most vegetative-movable species is H. rhamnoides, forming very dense shrubbery. Vital state of different age plants and their stool shoots is high-leveled even in droughty years, such as second half-year of 2015. It is experimentally proved that isolated from maternal plant stool shoots form own root system; these isolated individuals are potential new sources of H. rhamnoides, P. alba and P. italica distribution at the dumps. We transplanted seedlings of these species at the dumps in spring and in autumn. We devised and got patents for utility models "The method of using common sea-buckthorn for recultivation of iron ore dumps in Kryvyi Rih area" and "The method of using white poplar for recultivation of iron ore dumps in Kryvyi Rih area". Scientific novelty and technological advantage of project: transplanting of seedlings of vegetative-movable species at the iron ore dumps does not require financially expensive technical stage of recultivation; surface of dumps is not covered by soil for next transplanting of seedlings. For the first time in Ukraine we proposed common sea-buckthorn and white poplar to mass use for greenery planting at the iron ore dumps. The elimination of financially expensive technical stage of recultivation by using vegetative movable species H. rhamnoides, P. alba і P. italica (these species recrudesce at the dumps every year) reduces several times the expenses for greenery planting of 1 ha of dump area. It is advisable to use stool shoots of mentioned species growing at the dumps, if these stool shoots have own root system. This method allows not to transplant seedlings in the whole surface of dump, thus nurture of large number of seedlings is not required too. Key words: VEGETATIVE MOVABLE ARBOREAL SPECIES, IRON ORE DUMPS OF KRYVYI RIH AREA, GREENENERY PLANTING METHODS.
