Abstract

This research presents the results of long-term studies into the vegetation of technogenic landscapes of Yakutia using the method of the ordination of species along successional time. The objects of the research are refuse heaps of gold deposits in South Yakutia; chronoclines, arranged by mode values from the earliest intruders into succession on young heaps to the established species on older heaps (over 20 years). The research discovered a general pattern in changes of species and time of appearance of various species in the succession, the duration of their presence as part of seral communities. 5 groups of species were identified: 1) the group of species of "flow-through" spread; 2) the group of species gravitating towards early stages of succession; 3) the group of species gravitating towards middle stages; 4) the group of species gravitating towards later stages; 5) the group with bimodal distribution. Groups of species selected by age of refuse heaps on mineral deposits determine the degree of vegetation overgrowth because of the climate of a region and mining technology. The authors identified patterns in revegetation of gold deposits heaps in South Yakutia in order to determine the reclamation potential of disturbed lands.
