The aim of the work is to develop scientific foundations for revitalizing eroded landscapes for the use of rare plants and valuable introduced species.

The search and development of ways to prevent soil erosion processes when using little-known autochthonous and introduced plant species have been carried out. Woody plants, which are proposed for fixing eroded slopes – the genus Malus Mill., handicraft – plants of the genus Elaeagnus L., multiflorous oak (Elaeagnus multiflora Thunb.), herbal – plants of the species of the genus Astragalus L. Their biochemical composition and alelopathic properties have been established under culture conditions compared to the conditions of the model site. It was determined that all introduced species have a sufficiently high adaptive capacity and good adaptation to conditions with a low level of fertile soil layer, moisture content and a high level of insolation.

For the comprehensive preservation and restoration of the native flora and soil cover, we suggest planting plants of the genus Malus according to the principle of a checkerboard with the addition of representatives of the genus Elaeagnus, creating a continuous grass cover from representatives of the genus Astragalus and autochthonous herbaceous plants. Apple trees and Elaeagnus bushes will infiltrate excess moisture from the soil profile at different depths and anchor the soil profile with a root system. Representatives of the genus Astragalus, due to early regrowth and the ability to form a dense herbage, will reduce the degree of insolation on the soil surface, slowing down the intensity of water evaporation, thanks to a powerful root system, they will increase the density of the soil-root horizon and accumulate nitrogen necessary for the life of other plants. During the entire growing season after each mowing, plants of the species of the genus Astragalus will also serve as an organic fertilizer for the soil, thereby increasing its fertility.

Scientific novelty Recommendations have been developed for the rational use of the ecological potential of risk areas, an assortment of plants promising for the revitalization of eroded landscapes of Ukraine has been established, optimal conditions have been created for rare plants and valuable introduced species that will ensure high decorativeness and durability of plantings, their economic efficiency and expediency of use have been substantiated.
