Over a period of 3 years, medicinal plants were investigated in the reserve Gorna Topchiya, situated in the middle course of the river Toundzha near the village of Konevets, Yambol, Municipality Tundzha (Tundzha hilly valley). Vegetation seasons included the period from February to October, which guarantees the traceability of growing cycles of both annual and perennial species, as well as ephemeral and ephemeral-like species. In the present study we did eco-biological characteristics of these plants, as the species are divided into biological groups according to their life forms, floral elements and flowering time. Medicinal plants are also classified according to their relation to water, light and heat. We have made conclusions about the influence of hydrodynamics on the change of floristic composition and the changes that occur in cenosis characteristics of the protected area.

Key words: reserve Gorna Topchiya, River Tundzha hilly valley, floristic characteristics, environmental features, medicinal plants, conservation significance
