The results of the study of the species composition dynamics in successive plant communities developing on the northern slopes of the coal mining spoils dating back to the 70s, 80s, 90s and 2000s years in the arid areas of Khakassia, are presented for the first time. During the first 10-15 years of revegetation there was an increase in taxonomic diversity in the successive plant assemblages. Endemic species of the Fabaceae family, common for the bunch grasses steppes and stony steppes of Khakassia, were not found on the northern spoil slopes. Mesoxerophytes were the most abundant ecological group. Drastic increase in the complexity of the successive plant assemblages in the arid areas of Khakassia was found to take place after 25-30 years of revegetation.

The article presents results of the long-term studies of the structure and production of agrophytocenoses, established on the coal mining dumps in the Kuznetsk basin forest steppe zone. Agrophytocenoses were established on the leveled dumps by seeding grasses and legumes. Another set of control agrophytocenoses was established by the same technic on zonal soil. Seeds were provided by the laboratories of the Central Siberian Botanical Garden SB RAS, Novosibirsk. After 30 yrs of observations it was found that agrophytocenoses on the coal mining dumps did not have initial stage, as well as stage of spontaneous species invasion. Elimination of Trifolium pratense and Arrhenatherum elatius from coal mining dumps phytocenoses took place 3-4 yrs later than from agrophytocenoses on zonal soils. Species did not eliminate totally, but remained in communities with increased or decreased relative abundances. Significant number of species displayed fluctuation, rather than succession in course of 30 yrs development on the coal mining dumps. These phytocenoses It was also found that agrophytocenoses on the coal mining dumps have high long-term production potential.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
