The biodiversity of mountain vegetation is of high value not only for the animal and plant world but also as a factor in preserving the biosphere. In order to preserve biodiversity, the preserved biological objects were monitored, valuable forage grasses were sown, and after spring regrowth, the biological product NIKFAN was introduced in a concentration of 0.1% aqueous solution. The results of the experiments showed a more intensive growth of plants, an increase in both feed and seed productivity. Leguminous grasses were sown in degraded areas with the preliminary introduction of clay deposits of rocks. The results obtained are indicators of positive results for biodiversity conservation and reintroduction of mountain plant communities.
