Introduction. The Sinyukha river basin, in particular its southern part, is an area with a high level of anthropogenic pressure and a significant level of agricultural development (the proportion of agricultural land is more than 80%), with fragmented natural habitats. Detailed chorological study is needed to supplement the pattern of the distribution of rare plant species, to develop measures for their conservation, to optimize the existing network of protected areas in the region.Рurpose of the study isto analyze the current distribution and describe new finds of some rare plant species in the southern part of the Sinyukha river basin.Methods. The research was conducted in April-June 2021. We surveyed the area of the Sinyukha river valley from the village of Kalamazovo (Vilshansky district, Kirovohrad region) to its confluence with the Southern Bug River in Pervomaisk (Mykolayiv region), as well as – the valleys of its tributaries – Chorny Tashlyk, Malyi Tashlyk and Sukhyi Tashlyk. When locating a rare species, the plants were photographed and georeferenced at a point with GPS-navigator. Species cover is given according to the Broun-Blanquet scale. The distribution maps were performed by free QGIS software.Results.We revealed new and confirmed known localities of 20 rare species:Adonis vernalis, Asplenium septentrionale, Astragalus dasyanthus, A. odessanus, Bellevalia sarmatica, Clematis integrifolia, Crocus reticulatus, Dianthus hypanicus, Ephedra distachya, Hyacinthella leucophaea, Iris pontica, Iris pumila, Ornithogalum boucheanum, Pulsatilla pratensis, Primula veris, Sedum borissovae, Stipa capillata, S. lessingiana, S. pennata, Tulipa hypanica. Among the 20 identified rare species one has the category VU (Vulnerable) in the IUCN red list and belongs to the list of Resolution 6 of the Berne Convention; three species are narrowly local endemics of the Dnieper Upland; 11 are listed in the Red Book of Ukraine (5 of them have the status vulnerable, 1 – rare, 5 – insufficiently known); 5 species are regionally rare in Kirovohrad and 8 – in Mykolayiv regions. Most of the revealed species have a cover less than 5%. Only 9 of the 20 registered rare species characterized by more than five localities within the studied area. Originality. New localities of 20 rare species of plants of different levels of protection have been revealed. Prospects for conservation valuableof their habitats are offered.Conclusion. We have identified a significant number of new localities of rare plant species that are not covered by proper protection. This indicates the need for more detailed chorological research to elucidate the current distribution of rare species and the creation of new protected areas. Key words:rare species; threat category; red lists; natural habitats; chorology.

Pasture Digression

Degradation of natural habitats causes rapid extinction of rare plant populations. The diversity of rare plant species in the meadow steppes of Southern Opillya (Western Ukraine) depends strongly on patch area, pasture digression of vegetation and a variety of eco-coenotical conditions. The main threats for the rare components of the meadow steppe flora are reduction of habitat and overgrazing. Spatial connections between sites are unable to support a constant rare plant population. The analysis of the composition of rare plant meadow-steppe species indicated that habitats with similar rare species composition usually have similar parameters of area, stages of pasture digression and eco-coenotical conditions. Spatial connectivity of patches does not ensure species similarity of rare components of the flora. Rare plant species were grouped according to their preferences for habitat , area and condition. In small patches subject to any stage of pasture digression grow populations of Adonis vernalis L., Pulsatilla patens (L.) Mill., P. grandis Wender., Stipa capillata L., S. рennata L., Chamaecytisus blockianus (Pawł.) Klásková etc. On the contrary, populations of other species (Carlina onopordifolia Besser. ex Szafer., Kuecz. et Pawł., Adenophora liliifolia (L.) Ledeb. ex A. DC., Crambe tataria Sebeók, Euphorbia volhynica Besser ex Racib., Stipa tirsa Stev. etc.) prefer large habitats, not changed by pasture digression. Prevention of reduction of rare species diversity requires preservation (also extension) of patch area and regulation of grazing intensity.

Gagea minima (L.) Ker Gawl. is a rare species characteristic of meso- and eutrophic deciduous forest communities of the Fagetalia sylvaticae order. It is an inconspicuous spring geophyte easily overlooked in the field, occurring in oak-hornbeam and oak-beech forests, thickets, mountain glades and meadows. The paper gives information about the historical and present occurrence of G. minima within the administrative boundaries of the city of Kraków. Eight historical (6 published and 2 found in KRA herbarium material) and 4 new localities are described. The study demonstrates that rare plant species associated with natural forest communities may still occur in remaining fragments of these biotopes even within such a heavily urbanized area as the city of Kraków.

Rare Plant Species

Increasing anthropogenic pressure, global climate change, and the lack of large introduction centers in the Chernihiv region makes it important to preserve rare species of flora ex situ outside this administrative region. The article presents the results of the study of taxonomic composition and evaluation of the success of the introduction of rare plant species of Chernihiv region in the M. M. Gryshko National Botanical Garden of National Academy of Sciences of Ukraine. The study of rare plant species and the development of methods for their effective reproduction was initiated in the NBG in 1970 in a separate section “Rare plants of the flora of Ukraine.” It is established that the collection grows and protects 57 phythorarites of Chernihiv region, of which 29 species are listed in the Red Book of Ukraine (III edition), and 28 species – in the “List of regionally rare plant species of Chernihiv region”. Most plants successfully recover ex situ with moderate care or without additional human intervention. The biomorphological spectrum of introduced plants is dominated by cryptophytes (50.88 %) and hemicryptophytes (42.11 %), the shares of phanerophytes, hamephytes and therophytes are insignificant. 17 species of phythorarites formed stable homeostatic populations. Of these: 5 species are listed in the Red Book of Ukraine (Allium ursinum, Crocus reticulatus, Epipactis helleborine, Galanthus nivalis, Pulsatilla pratensis) and 12 species – in the “List of regionally rare plant species of Chernihiv region” (Aster amellus, Corydalis intermedia, C. marschal, Daphne mesereum, Equisetum hyemale, Iris hungarica, Phlomis tuberosa, Primula veris, Pteridium aquilinum, Scilla bifolia, S. sibirica, Vinca minor). Thus, the cultivation of almost a third of the phythorarites of Chernihiv region in the M. M. Gryshko National Botanical Garden testifies to the effectiveness of their preservation ex situ.

This report includes data on rare plant species of steppe and forest-steppe pine forests. We have identified the proportion of rare species that live in the studied forests for the regions where they are located, and for Russia as a whole. We have identified regional species found only in pine forests. The article shows that pine forests play an important role in the conservation of forest (boreal, boreonemoral, nemoral and boreonemoral forest-steppe) species and in the conservation of regional phytodiversity.
