(2007): Distribution, cenotic characteristic and protection of habitats of plants of the Bern Convention in East Polesye. – Thaiszia – J. Bot. 17: 33-58. – ISSN 1210-0420. Abstract: The author reports on the results of the studies on distribution, cenotic characteristic and analysis of protection of habitats of plants of the Bern Convention in East Polesye. In 1995– 2006 the species of plants, which are given in the list of Appendix I of “Convention on the Conservation of European Wildlife and Natural Habitats” were identified in this region. On quantity of sites in the studied region and geographical distribution the Bern Convention plants of East Polesye are divided in very rare (forest species Botrychium multifidum and Cypripedium calceolus ), rare (forest-marsh species Ostericum palustre ) and rather rare (forest species Pulsatilla patens , water species Salvinia natans and Trapa natans ). The maps of distribution of rare species are represented. The floristic structure of the plant communities with participation of these species is documented. Keywords: plants, distribution, cenotic characteristic, East Polesye, nature protection, Bern convention. Introduction With the purpose of development of strategy of protection of habitats of plants of wild flora, in especially disappearing and vulnerable, which are given in the list of Appendix I of “Convention on the Conservation of European Wildlife and 33 Natural Habitats” (1979) the systematization of information about all known habitats of these species in natural regions of Europe is necessary. With the purpose of development of strategy of protection of habitats of plants of wild flora, in especially disappearing and vulnerable, which are given in the list of Appendix I of “Convention on the Conservation of European Wildlife and Natural Habitats” (1979) the systematization of information about all known habitats of these species in natural regions of Europe is necessary. The object of our research is the subprovince East Polesye of province Polesye , which include Left-Bank of Dnieper in the borders of Byelorussia, Russia and Ukraine. In comparison with Northern and Southern Polesye the territory differs in more continental climate and less humidity, presence of loamy “islands” (MARYNYCH 1963) and also large anthropogenous loading. Subjects of research are the species of vascular plants, included „Application 1. Stricly protected flora species” of the Bern convention, in particular Botrychium multifidum (S.G. Gmel.) Rupr, Salvinia natans (L). All., Dracocephalum ruyschiana L., Cypripedium calceolus L., Pulsatilla patens (L) Miller, Trapa natans L., Ostericum palustre (Ben). Bess. The aims of the current studies were the following ones: 1) to establish recent distribution of plants of the Bern Convention in East Polesye, 2) to document the floristic structure of the plant communities with participation of these species. 3) to carry out the analysis of the provision of protection of Bern Convention plants in East Polesye Materials and methods There were used materials of N. Kholodny Institute of Botany of National Academy of Science ( KW ), T. Shevchenko Chernihiv State Pedagogical University (Ukraine) and F. Scorina Gomel State University (Byelorussia), data about distribution of rare species in Bryansk region (Russia). The geobotanical descriptions of habitats of Cypripedium calceolus has given O. Evstigneev (Bryansk Forest Reserve). The field researches were carried out during 1997 - 2006 at itinerary and demistationary study of flora and vegetation of East Polesye. The nomenclature of taxons is reduced on MOSYAKIN & FEDORONCHUK (1999). The description of discount areas was carried out in natural borders of phytocenosis. 44 geobotanical descriptions were executed. In identification of syntaxsons was used the syntaxsonomic schemes BULOKCHOV & SOLOMESHCH (2003), MATUSZKIEWICZ (2001), ONYSHCHENKO (2006): Results and discussion The natural habitat of Botrychium multifidum (S.G. Gmel.) Rupr covers Europe, Western Asia, Himalayas, Northern and Southern America, Australia. KLEOPOV (1990) refers this species to boreal geoelement of flora. On territory of 34 Ukraine B. multifidum is in southern border of distribution. It was known only single habitat of this species, which was found in 1882-1905 ( KW ) by A. Rogovich, V. Montrezor, I. Selejinsky on the territory of modern Ripky rayon (Chernihiv region) and Brovary rayon (Kyiv region). The recent locations of B. multifidum in East Polesye (Fig. 1). Fig. 1.
