Rare Plant Species

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.

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.

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.

Identification of valuable biotopes was carried out on the example of a small territory —the “Gagarka” forest park, located on the Northern coast of the Gulf of Finland within the borders of St. Petersburg (Fig. 1). Field data on landscapes, vegetation, flora and fauna were collected in 2018 to proof the need to create a specially protected natural territory of regional significance. The study area of 58.7 ha is an accumulative sea terrace with absolute elevations not exceeding 2.5 m above sea level. Despite of small area size, the vegetation is quite diverse and it is represented by the coniferous (spruce and pine) forests, several types of black alder forests, tree and shrub fens, littoral meadows, coastal and aquatic vegetation. Rare species of herbaceous plants and shrubs listed in the Red books of the Russian Federation (Krasnaya…, 2008) and St. Petersburg (Krasnaya…, 2018) are recorded and they often dominate in the plant communities. The preservation of biological diversity may be successful only if the landscapes and the biotopes hosting plant and animal species, including rare ones, are protected. Objects of protection can be both rare and typical ones for the regional biotopes. The environmental value of biotopes of the “Gagarka” forest park was assessed according to the following criteria: ecotopic (areas with rare and specific landforms, soils, hydrochemical regime), geobotanical (the presence of primary plant communities, rare plant communities; widespread, but with a tendency to reduce the area as a result of natural or anthropogenic impacts), floristic (the presence of rare species and species located on the border of their ranges), faunistic (the pre­sence of rare animal species, the species richness of fauna, the presence of permanent habitats of animals and birds, as well as biotopes used in certain seasons: during breeding, nesting, molting and migration). In addition, the compliance of biotopes with the European habitat classification EUNIS (European Nature Information System) was taken into account (Davies et al., 2004, EUNIS, 2018). Plant communities are the main indicator of habitats, and their borders mark the boundaries of habitats. In this regard, the geobotanical map (Fig. 2) is the basis for creating a map of biotopes. In addition to the geobotanical map, the map of actual landscapes, the map of the locations of rare plant species, and faunistic materials were used to create a map of valuable biotopes (Materialy…, 2018). It shows 6 types of habitats, that are particularly important for the conservation of biological and biotopic diversity (Fig. 3). All valuable habitats of the “Gagarka” forest park are located in the littoral zone of the Gulf of Finland and near its coast. They are grouped into 4 categories: black alder forests as a model of natural tree communities of the Littorina terrace and habitats of rare plant and animal species, coastal fens as rare plant communities on the territory of St. Petersburg and habitats of rare plant species, littoral meadows as rare plant communities on the territory of St. Petersburg and habitats of rare plant and animal species, shallow waters of the Gulf of Finland as habitats with highly productive communities of macrophytes, rare plant species, with a large species diversity and a high number of birds, including rare ones. The creation of new protected area “Gagarka” is necessary to preserve the habitats and rare species that grow and live here.

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.

As a result of long-term studies of natural forests in the Rostov region, more than 450 geobotanical descriptions of natural forest vegetation were performed, an inventory of forest flora and an ecological and floral classification of vegetation was carried out. Forest communities are described, represented by 6 classes (Carpino-Fagetea, Quercetea pubescentis, Alno glutinosae-Populetea albae, Alnetea glutinosae, Salicetea purpureae and Crataego-Prunetea), 7 unions (Scillo siberica-Quercion roboris, Aceri tatarici-Quercion, Alnion incanae, Alnion glutinosae, Salicion albae, berberidion vulgaris, Prunion Fruticosae) and 18 associations, 9 subassociations and more than 40 variants, 10 un-ranked communities. Plant species listed in the Red Book of the Rostov region (2014) were noted, including 9 species of Federal protection status, 8 species listed in the IUCN Red List (2014), and 11 species listed in the European Red List (2011). 75 rare species of plants were found in the natural forests of the region. After analyzing the geobotanical descriptions, the rare species were divided into 6 groups, relative to the topographical and historical characteristics of the forest. Key areas in forest areas for monitoring rare plant species are proposed and justified. A list of species recommended for inclusion in the new edition of the Red Book of the Rostov region has been compiled.

Efforts to conserve rare plant species can be limited by a lack of time and funding for monitoring. Understanding species occurrence and distribution patterns within existing protected habitat and throughout the entire species range can help stewards prioritize rare plant monitoring. We created a database of rare plant occurrences from public, private, and research sources to analyze the distribution of rare plant species throughout the existing protected area within the Nature Reserve of Orange County in California, USA. We analyzed species occurrence relative to the urban edge, roads, trails, and mean high tide line. We also determined the vegetation community with the highest number of rare plant species to help prioritize habitats for conservation and restoration. We found that some parts of protected areas have more rare plant species and we also found sampling biases on the location of occurrence data. We found that rare species occur close to roads and trails and the mean high tide line. Rare species were in all vegetation communities within the reserve, including degraded areas. Using patterns of distribution and considering the immediate threats to a rare species population can help land managers and stewards prioritize monitoring toward the most threatened species.

Rare Plant Species

The presence of numerous publications on populations is explained by the exceptional value of this branch of knowledge for understanding of the structural and functional organization of wildlife, natural resource exploitation, management and conservation of them for future generations. A short list of scientific directions in the study of the role and place of a population shows that in the scientific literature there are no studies of rare plant species populations, development of theoretical principles and methodology of their study. The experienced team of the Botany Department of Sumy National Agrarian University has started this work. Not regard to the objective of comparison and disclosure of several publications on this topic, you must immediately emphasize its originality, depth of knowledge of the problem, innovation, and the importance and need for conservation of biological diversity of vegetation, which is often in a state of crisis and requires urgent measures to save it. The book was published by the editorship of the well-known biogeocenologist and ecologist, Doctor of Biological Sciences, Professor, Honored Scientist of Ukraine Julian A. Zlobin together with well-known scientists in the filed of ecology and biogeocenology of Yu. A. Zlobin scientific school Victoria G. Sklar and Anna A. Klimenko. Structurally, the monograph consists of thirteen chapters, conclusion, bibliography and applications. A special place is occupied by the section "Methodological blocks", which is a kind of satellite for each section and which equip the reader with modern methodological approaches to complex problems solution of the population structure of the plant world. Here the authors examine the current level of rare species research organization, complexity and pivotal scientific idea, which is an organizing and centripetal force of varied complex research. There are four scenarios, which aim the saving, restoration, protection and rational use of the planet's vegetation. The book summarizes the collective work for one of the most important problems of modern biological science - conservation of rare plant species. Helpful tips for the organization of similar research in scientific institutions, biogeocenological stations by well-organized scientifically based plan at the level of the modern achievements of environmental science are given. In general, we believe that the reviewed scientific work of Yu. A. Zlobin, V. G. Sklar, A. A. Klimenko "Populations of rare species of plants, theoretical principles and methods of the study" is a major contribution to the scientific literature on ecological populations of rare species, their functions, complex relationship in vegetation cover. It will undoubtedly find a positive response in the wide circles of geobotanists, ecologists, biogeocenologists in our country and abroad.
