Mulching as a restoration method of revegetation at ash and slag dumps of Burshtyn TPP

Abstract

The study of the effect of mulching to establish vegetation cover at industrial sites is promising and relevant in terms of environmental restoration and reduction of environmental risks in the area of influence of industrial facilities. The study aims to investigate and evaluate the effectiveness of mulching and sowing seed mixtures as a method of establishing vegetation cover at ash and slag dumps of thermal power plants. To conduct the study, the soil cover of ash and slag dumps was assessed, and experimental plots were laid out for mulching and sowing seed mixtures. The study revealed that ash and slag dumps ecotopes are characterised by a high concentration of pollutants, namely heavy metals, which makes it difficult for vegetation to grow there. In the course of studying the ecological features of the ecotopes and phytodiversity of the territory, a list of species of native flora for seed mixtures was proposed. Mulching was done on the experimental plots and seed mixtures were sown. Mulching has proven to be an effective method for accelerating the processes of natural regeneration of vegetation in areas affected by anthropogenic impact. The results of the study can be used in practice by ecologists, environmental organisations, and a wide range of specialists to develop and implement measures to restore the ecological balance of degraded and technologically transformed ecosystems
