NEW VASCULAR PLANT SPECIES PROPOSED FOR THE REGIONAL CONSERVATION IN POLTAVA REGION

Abstract

During field expeditions in 2005–2018 in Poltava region author found 12 vascular plant species which are very rare on this territory and need conservation. He proposes to include them in the List of regionally rare plant species within Poltava region. These plant species are: Carex brevicollis DC. (relict nemoral Submediterranean species with isolated localities near Poltava town), C. remota L. (mostly Central European nemoral plant on the eastern border of range), Brachypodium pinnatum (L.) P. Beauv. (rare species on the southern border of the flat part of range), Corydalis intermedia (L.) Pers. (rare nemoral ephemeroid plant on the southern border of range), Arabis pendula L. (locally distributed Eastern European-Asiatic species on the western border of range), A. turrita L. (relict nemoral Submediterranean species with isolated locality in Dykanka district), Rubus nessensis W. Hall (boreal shrub species on the southern part of range), Cirsium rivulare (Jacq.) All. (locally distributed European swampy species), Rhaponticum serratuloides (Georgi) Bobrov (rare Eurosiberian halophyte species on the western border of range), Saussurea amara (L.) DC. (rare Eastern European-Asiatic halophyte species on the southern part of range), Senecio czernjaewii Minder. (locally distributed in oak-pine forests Euro-Siberian species on the southern part of range), S. paucifolius S.G. Gmel. (locally distributed Euro-Siberian species on the western part of range found in steppes and salt meadows). For all these species proposed conservation category, data about distribution (with full list of known localities), ecological and coenotic conditions, quantity of populations, conservation proposals and literatural sources has been also indicated.
