Floristic Research of the Biological Reserve “Bragunsky”
Abstract
Flora of the biological reserve “Bragunsky” of republican significance, located on the territory of three districts of the Chechen Republic (area of 17,000 hectares, forest land – 10.2 thousand hectares) is studied. Its boundaries are indicated. Preliminary studies in the summer-autumn flora of the reserve have revealed 237 species from 175 genera and 53 families, among which more than 15 endemics are of different statuses, 25 relict species are of different geological eras. Dominant by the number of family species are indicated (Asteraceae, Lamiaceae, Rosaceae, Poaceae, Fabaceae, Caryophyllaceae, Apiaceae, Brassicaceae, Cyperaceae, Scrophyliaceae, Orchidaceae), Geographic elements are considered. The general-holarctic and boreal nature of the flora is noted with a significant participation of ancient Mediterranean and binding elements. The prevalence of hemicryptophytes in the reserve flora has been noted – 115 (49.78 %) species, 48 therophytes (20.25 %) and 40 phanerophytes (10 %) and a slight presence of cryptophytes – 4.21 %. The economically and scientifically valuable, as well as rare, red book and protected species are listed.
