Abstract
The aim of the work was to study the adaptation of tree and shrub vegetation during the reclamation of silt ponds, which have a significant impact on the environment. Forest reclamation of the storage pond will reduce the emission of gases into the atmospheric air, as well as reduce the evaporation surface from the pond area. The main indicator of the adaptation of plants to the conditions of the new environment is their safety, which shows the percentage of surviving plants to the number of planted. To create a solid foundation, the surface of the sludge pond was covered with the mineral residue of sand from sand traps, which is formed in the process of wastewater treatment at wastewater treatment plants. The results of determining the content of heavy metals in the soil testifies that all the studied samples meet the requirements of these technical conditions in terms of the content of heavy metals. Zinc, chromium, copper are present in the greatest amount in the analyzed samples, and arsenic, cadmium, and mercury are absent. The surface of the silt pond was subject to forest reclamation with various tree species. Experimental plantings were evaluated for safety, depending on the presence of leaves and viable buds on the trees. As a result of adaptation to extreme growing conditions, some deciduous species had a higher survival rate in the current year compared to the previous year, due to the restoration of foliage and resumption of growth from dormant buds.
