KOEV, K., A. TASHEV and S. GEORGIEV, 2015. Eco-biological characteristics of the flora in the floodplain forests of the maintained reserve “Dolna Topchiya” (the river Tundzha hilly valley). Bulg. J. Agric. Sci., 21: 523–529

The floristic diversity of the maintained reserve “Dolna Topchiya” was studied for a period of 3 years; the reserve is located in the middle reaches of the river Tundzha near the town of Elhovo (Tundzha hilly valley). The vegetation seasons include the period from February to October, which guarantees tracking the cycles of development of annual and perennial species, as well as the ephemeral and ephemeral-like species. In the present study we made eco-biological characteristics of these plants, and the species are distributed in biological groups, life forms, floral elements and flowering time. Plant species are grouped according to their relation to water, light and heat. We draw conclusions about the influence of hydrodynamics on the changing floristic composition and also on the changes occurring in the cenosis characteristics of the protected area.

Key words: The maintained reserve “Dolna Topchiya“, floristic characteristics, eco-biological characteristics, medicinal plants, conservation significance
