Abstract
The article presents the results of phytosozological assessment of the «Drabynivka» Botanical Reserve territory (Kobeliaky district, Poltava oblast). The flora of the Nature Reserve includes 488 species from 294 genera, 80 families, 44 orders, three classes and two divisions. The rarity is made up of 38 species, 37 of which have sozological status, and one (Stachys germanica) requires its assignment. Nine species are included into the Red Book of Ukraine (Adonis vernalis, Adonis wolgensis, Anacamptis palustris, Bulbocodium versicolor, Fritillaria ruthenica, Tulipa quercetorum, Ornithogalum boucheanum, Crocus reticulatus, Stipa capillata). 27 species are regionally rare and are therefore protected within Poltava oblast limits. One of the species is included in the CITES Convention Annex (Adonis vernalis), another one is in the World Red List (Trinia kitaibelii), one species requires preservation at the regional level (Stachys germanica).Stipa capillata groups are included in the Green Book of Ukraine. The article presents the state of distribution and general characteristics of rare flora species coenopopulations state in the Reserve. Ecological risks for phytodiversity preservation have been identified. The directions of the Reserve territory optimization and expansion of its area for full-rate functioning as a key territory of the regional ecological network local eco-corridor are outlined.
