Раритетне фіторізноманіття ключових територій екологічної мережі Центрального Придніпров’я

The article provides information about the rare phytodiversity of key areas of the ecological network of the Central Dnipro region. The basis of the key territories was such protected areas as reserves of national importance. The Law of Ukraine “On the Nature Reserve Fund of Ukraine” stipulates that nature reserves are created to preserve natural complexes. The aim of the work is to provide information on the location of rare phytodiversity in the reserves of national importance in the Central Prydniprovia; to carry out a systematic, biomorphological and ecological-morphological analysis of rare flora species; to characterise the lists of rare flora species according to sozological lists of different levels: international (IUCN), World Red List, European Red List, Bern Convention, CITES, national (Red Book of Ukraine). There are 26 reserves of national importance in the Central Prydniprovia region (Cherkasy oblast — 4 sites, Kirovohrad oblast — 22 sites), including 10 botanical reserves, 9 landscape reserves, 3 ornithological reserves, 2 hydrological reserves, and 1 forest and 1 general zoological reserve, respectively. The location of the reserves of national importance in the Central Prydniprovia is rather uneven. The results of the distribution of rare phytodiversity in the reserves of national importance are presented, and an analysis of the systematic and biomorphological structure is presented. Families: Orchidaceae has 9 genera and 12 species; Fabaceae –2 genera and 5 species; Liliaceae — 3 genera and 4 species; Iridaceae and Ranunculaceae — 2 genera and 4 species; Poaceae — 1 genus and 4 species, Asteraceae — 2 genera and 2 species. These families account for 66.0% of the species and 57.6% of the genus diversity of the rare flora, while the remaining 10 families have from one to two species and genera. The largest number of locations on the territory of the reserves was recorded for the species: Pulsatilla pratensis (L.) Mill. s.l. — 13 specimens; Astragalus dasyanthus Pall. — 9 specimens and Adonis vernalis L. — 8 specimens. The distribution of rare phytodiversity by the level of protection (interstate and national) was made. Thus, reserves of national importance are important key areas for the ecological network and have a rare floristic core of species.
