Restoration of plant communities on various dump substrates

Abstract

The results of field studies in 2018 and 2019 at the pilot production site on the territory of the external dump “Zarechny” of JSC SUEK-Kuzbass are presented. The ecological and coenotic characteristics of plant communities formed in the areas with the filling of the fertile soil layer (FSL) (0.5 m thickness), with the application of potentially fertile rocks (PFR) (1 m thickness), in the area with the filling of technogenic eluvium, as well as in the area with the layer-by-layer filling of PFR (0.6 m thickness) and FSL (0.4 m thickness) were studied. Geobotanical descriptions were carried out according to standard methods, taking into account iterations. It is established that in the first years after the end of the formation of the pilot production site, the number of herbaceous plant species increases in all areas. However, the use of lithogenic resources in the frame of reclamation accelerates the development of plant communities on man-made landscapes, but does not allow reaching the stages of zonal formations.
