Features of the islands' flora of the Zabaikalsky National Park
Flora species diversity is very high due to the variety of ecological conditions on the seven islands ofChivyrkuysky Bay. It is presented by 314 species of vascular plants (178 are mentioned for the islands for the first time and18 species for the National Park), referring to 186 genus and 60 families. Floristic abundance of the islands has positivecorrelation with their sizes. Composition and structure of islands' flora let us consider it almost entirely successively andinseparably linked to flora of the Barguzinsky Ridge and Svyatoy Nos Peninsula surrounded by Chivyrkuysky Bay. Atthe same time, they reflect main structural features of flora of Lake Baikal Siberia. In general, our analysis characterizesislands' flora as boreal semihubid, and floristic wealth is contingent on biotopical diversity
