THE ROLE OF NATURAL RESERVE FUND OF POKUTSKA PART OF PRUTDNIESTER AREA IN THE PRESERVATION OF PLANTS FROM THE RED BOOK OF UKRAINE

Prut-Dniester watershed is a natural unit with distinct natural boundaries where favorable climatic and orographic factors caused its strong but uneven human transformation. Today natural vegetation between rivers Prut-Dniester due to the strong dismemberment and uneven distribution of the territory is insular by its nature except for Khotyn hills and steep banks of the river Dniester. Moreover, the presence in the territory between Prut-Dniester special karst topography, promotes local groups and isolated populations that can be considered as centers of conservation and "conservation" phytodiversity. Pokuttya Territory (eastern part of Ivano-Frankivsk region, including the territory of Horodenka, Kolomyya, Snyatyn and Kosiv districts) is a part of the territory between the Prut-Dniester, occupying almost a third of its area. At the Pokutska of the Prut-Dniester interfluve there are 112 protected areas, representing nearly 46% of protected areas between the rivers Prut-Dniester and covers more than 56% of protected areas. Area of 80% of these areas does not exceed 5 ha. In the flora of the studied region 56 species are growing and listed in the third edition of the Red Book of Ukraine. Rare flora Pokutska component of the Prut-Dniester interfluve represented 21 family. The most numerous among the rare species is a family Orchidaceae, which accounts for 32% of the rarity phytodiversity Pokutsko Prut-Dniester rivers. In the research in the natural reserve fund 37 rare protected species is 66% Red Book Pokutska of the Prut-Dniester rivers. It is established that 19 species of the families Euphorbiaceae, Cabbage, sedge, onion and moss grow outside the protected areas and are not currently equipped with proper protection. Of the 112 protected areas in the region only in the research discovered 36 rare species of flora. Most of these facilities provides safety from 1 to 5 of rare species, due to their small area
