According to the goals and objectives of the Global Strategy for Plant Conservation for 2011–2020 studying and monitoring the rare component of regional floras is highly relevant. This article presents the results of a nature conservation study of the flora of the Desna Plateau (Кrolevets’ and Hlukhiv geobotanic region), situated in the northeast part of Ukraine at the border line of two geomorphological regions (the Central Russian Upland and the Polesia-Dnipro lowland) and of two physical-geographical zones (Novhorod-Sivers`ke Polesia and the Sums`ky forest-steppe. In the orographic aspect, the territory is made up of the western spurs of the Central Russian Upland with the dissectioned forms of the relief. The studied area consists of about 4000 km2. Field route studies aimed at compiling floral lists, geobotanical description and herbarizing were conducted in the period 2002–2016. Separate sites of nature conservation interest were re-examined in different seasonal periods. The basis of the annotated summary of the rare species of vascular plant flora is made up by the materials of original research, as well as herbarium (KW) and literary reviews. The complex floristic analysis of the rare component of the regional flora was carried out in cameral conditions, which made it possible to identify the systematic, geographical, ecological, phytocenological and nature conservation structures of the rare species of vascular plant flora in the investigated area. According to the data received, the total number of species of vascular plants endangered by anthropogenic impact is composed of 85 species belonging to 32 families, 54 genera. Among the families, the following predominate: Orchidaceae (14 genera), Asteraceae, Ranunculaceae (8 genera in each), Iridaceae (5), Aspidiaceae, Cyperaceae (4 genera in each). Among the genera, the following predominate – Carex (4 species); Dryopteris, Orchis, Iris, Jurinea – 3 species in each. It was concluded that among the rare species there are plant species of different physical and geographical zones and this corresponds to the ecotone location of the region. Among species at the edge of their range, 14 are on the extreme northern border of their typical range (Linum flavum L., Carex rhizina Blytt ex Lindb., Centaurea ruthenica Lam., Trinia multicaulis Schishk, Aster amellus L., Galatella linosyris (L.) Rchb. f., Stipa tirsa Steven), 7 species are found on the southern border of their range (Cypripedium calceolus L., Pedicularis sceptrum-carolinum L., Parnassia palustris L., Lycopodium annotinum L., 4 species (Anemone nemorosa L., Salix myrsinifolia Salisb., Galanthus nivalis L., Gladiolus imbricatus L. are found on the eastern border of their distribution. The nature conservation structure includes 4 species from the Bern Convention on the Conservation of European Wildlife and Natural Habitats (Dracocephalum ruyschiana L., Pulsatilla patens (L.) Mill s.l., Salvinia natans L., Ostericum palustre (Bess) Bess); 3 species from the supplement to the CITES Convention (Adonis vernalis L., Cypripedium calceolus L., Orchis militaris L.), 27 species from the Red Book of Ukraine (Lilium martagon L., Allium ursinum L., Neottia nidus-avis (L.) Rich, Stipa pennata L.), 49 species from Sumy region rare species list (Clematis recta L., Pulsatilla patens (L.) Mill., Eremogone saxatilis (L.) Ikonn., Drosera rotundifolia L., Pedicularis kaufmannii Pinzg., Carex limosa L., C. umbrosa Host.). In addition, we suggest including into this list Sanquisorba officinalis L., Briza media L., Beckmania eruciformis (L.) Host., Melica nutans L., Coronilla varia L., Salvia nutans L., Scilla siberica Haw., Corydalis solida (L.) Clairv., Valeriana officinalis L., Vincetoxicum hirundinaria Medic., Menyanthes trifoliata L., Hesperis matronalis L., Naumburgia thyrsiflora (L.) Rchb., Thalictrum aquilegifolium L., T. minus L., Verbascum nigrum L., Polygonatum multiflorum (L.) All. It was found that among the rare species of the region mesophytes predominate and they are confined to meadow and forest habitats. To a lesser extent, xeromesophytes and xerophytes of meadow-steppe, as well as hygrophytes and hydrophytes of shoreline and water habitats are represented. The nature reserve fund of the region was analyzed according to the methodology of assessing the nature reserves by botanical value priority criteria. To optimize the region's nature reserve fund, a rationale for creating a landscape reserve of local significance “Zvenyhorods'ky” with a total area of 2,000 hectares was compiled, giving it the status of a regional biodiversity centre.

AbstractThe paper presents analysis of the results of floristic studies carried out over 25 years in the Viešvilė State Strict Nature Reserve (VSSNR) and its buffer zone. The list of 703 vascular plant species including the data on their distribution and dynamics of abundance are provided. The native flora of the VSSNR includes 580 species, i.e. amounts to 47% of all native vascular plant species recorded in Lithuania. Since 1991, after the establishment of the Reserve, 15 species have become extinct and 30 have become endangered as a result of natural succession. Among 37 alien species recorded in the Reserve, four species are penetrating into natural habitats and threatening their existence. It was ascertained that about half of all species were recorded in meadows and glades of the forests, i.e. in the habitats, which occupy less than 1% of the whole territory. These are also habitats of most extinct and endangered species. Riparian and fontinal black alder woods are the most rich in vascular plant species among forest habitats.

Reserve Fund

The development of the nature reserve fund of Ternopil region over the last 30 years has been analyzed and the current situation has been assessed. A significant increase in the number (by 236 units) of protected areas and an insignificant increase of area of the nature reserve fund (by 21.34 kha) have been showed. There are 643 objects in the nature reserve fund of Ternopil region (January 1, 2020). The nature reserve fund of this region includes all categories of protected areas except for biosphere reserves. The nature reserve fund of Ternopil region is able to ensure rational and effective reproduction and preservation of landscapes, unique natural objects, valuable and rare species of flora and fauna. The problems in the formation of the nature reserve fund of this region have been identified. There are such problems as low percentages of nature reserves and strict nature reserves; high insularization index, low degree of landscape representativeness; unregulated and unauthorized anthropogenic activities. The measures of effective functioning of the protected areas network has been suggested. The action points include such measures as an increase of the area of the nature reserve fund of Ternopil region to the average level in Europe (15 %); increasing the area of ecologically unstable areas to 50 ha; creating the conditions necessary for the preservation, restoration and balanced use of protected areas; reducing the anthropogenic load on protected objects; raising public awareness of tourist and educational services provided by protected areas.

The aim of the work is to supplement and clarify the annotated list of vascular plants of “Castel” nature reserve on the Southern coast of the Crimea. Methods. The work is based on the results of long standing field research, which was carried out by the traditional route-reconnaissance method, analysis of YALT herbarium materials and data from literary and Internet sources. Arealogical and biomorphological characteristics of species are given according to "Biological Flora of the Crimea" by V.N. Golubev, biotope coding according to EUNIS habitat classification. The nomenclature of taxa corresponds to the " Spontaneuos flora of the Crimean peninsula" by A.V. Yena and to international databases Euro+Med PlantBase, The Plant List, Catalog of Life. Results. An additional annotated list of vascular plants of “Castel” nature reserve has been compiled, including 152 species, subspecies and cultivars from 97 genera of 38 families, of which 53 genera and 11 families have also not been cited for this territory before. Arealogical, biomorphological, biotopic and sozological characteristics of the taxa are given. As a result of a critical analysis of the list previously published by E.S. Krainyuk, four species were redefined, two species were proposed to be excluded from the flora of the specially protected natural area, several taxa are considered doubtful. Conclusions. The list of vascular plant taxa in “Castel” nature reserve has been supplemented with 11 families, 53 genera, and 152 species, subspecies, and cultivars; several species from the previously compiled list have been proposed to be excluded or considered doubtful. Thus, the flora of the protected area includes at least 425 species from 68 families. For the first time, the biotopic characteristic of the flora of the reserve was established.

Abstract Cypripedium calceolus is considered an endangered species in the territory of Poland. Population of this rare species, situated at Lake Kwiecko (Western Pomerania), was regularly monitored in the years 1986-2013. The studied population has been under the permanent influence of the nearby hydroelectric power plant for almost 45 years. The field observations showed that the power plant had no negative impact on the condition of Cypripedium calceolus population. An indication of its good condition was, among others, an increase in the size - from 150 to 350 specimens within the study period.

The Impact

Examination of air photos from 1930, 1970 and 2002 revealed stands of the European Scots Pine (Pinus sylvestris) invading remnants of natural Corema (Corema conradii) heathland in the Annapolis valley. To document the impact of the introduced pines, four natural habitats were compared with two adjacent habitats already invaded by the pines. All surveyed habitats had been dominated by Corema heath based on air photos taken in 1930. Twenty 1 m2 quadrats were used to record presence and cover of vascular plants at each site. The invasive alien pines reduce the native cover to 12%. Vascular plant biodiversity is reduced to less than 42% and the cover of the heathland dominant, Corema conradii, is reduced from over 100 % to less than 2%. with Deschampsia flexuosa becoming the dominant species. The modified ecosystem and loss of biodiversity has economic impacts through loss of pollinators of agricultural crops and loss of germplasm of native crop relatives.

Classification scheme of rare habitats of Europe according to Bern Convention and Habitat Directive of EU was presented for the territory of Drevlianskyi nature reserve. It was shown significant habitat’s diversity of nature reserve from all main types of habitats — water (permanent and temporary lakes (waterbodies), watercources, reedbeds habitats), bog (eutrophic and mesotrophic mires), grassland (dry, mesic and wet grassland, floodplain and fen scrub, heaths), forest (leaved and conifer forests (woodland), rock (rocks and talus of silicate rocks). According to the results of field research, the territory of the reserve represented by 30 habitats (1 — ІІ leaves, 4 — ІІІ leaves, 25 — ІV leaves). It is established that the most common habitat 91T0 (Central European lichen Scots pine forests), which represented by 153 localities in A1C (dry pine forest) on an area of 421.5 ha. It was made a conclusion that the role of rare habitats in nature reserve Drevlianskyi is determinant for conservation of rare species of vascular plants that are protected by the Bern Convention, European Red List and included to the Red Book of Ukraine. The results of the analysis of the role of rare biotopes of Europe in the conservation of species of flora of different protection status on the territory of Drevlianskyi nature reserve show that most of the rare plant species of reserve listed in Resolution № 6 of the Bern Convention (Annex I), revised in 2011, are present in its rare settlements. The role of rare habitats of Drevlianskyi nature reserve in the conservation of rare species of flora is decisive — of the 29 species of plants of supranational and national levels of protection in rare habitats there are 24 species or 82.8% of their total number.

The paper contains a synopsis of rare component of flora of Halych National Nature Park forest ecosystems, as well as evaluation of distribution trends of rare vascular plant species and the state of their populations. Being established in 2004, the Park is located in Halych district of Ivano-Frankivsk region on the area of 14684.8 ha. Forests occupy the biggest part of its territory (81.1 %), among which predominate poor and mixed oak (Querceta roboris), beech (Fageta sylvaticae) and hornbeam (Carpineta betuli) woods. Inventory check of plant cover of the forest ecosystems has been done between 2008-2019 years. According to the results of our study, within the forests and forest margins grow 303 vascular plant species, out of which 63 are rare (20.8 %). The list of rare species is composed of species included to the Red Data Book of Ukraine, of species protected by international conventions and directives and complemented by species that are threatened within the study region. Species were considered as threatened if the number of localities and / or population size were small. Regionally rare species were selected based on the analyzes of results of our field survey and materials of herbarium collections. We have found that the third part of rare species (33.3 %) has high coenotic amplitude and a bit less species (26.2 %) favor forest margins. Rare species having low coenotic amplitude are confined to beech woods (19.1 %). Rare species are considerably distinguished by occurrence. Species with scarce occurrence predominate. For instance, 61 % of the species were found in 1-5 localities, of which 25 species occur only in one or two sites. Share of species growing in 6-10 localities within the Park is equal to 26.6 %. Only a small percentage (6.2 %) of rare species comprises species with relatively frequent occurrence (11–20 localities as well as more than 20 cites). Rare species of the Park forests with the highest occurrence rate are Lilium martagon and some members of Orchidaceae family. Predominantly, rare species have populations of small size, for instance, 81.2 % of the species were found in quantities of a few plants – several hundreds of individuals. The most threatened are species general number of which at the Park area is several plants (15.6 %). These species are as follows: Circaea alpina, Atropa bella-donna, Campanula latifolia, Phyteuma spicatum, Epipactis atrorubens etc. The biggest groups comprise species with general number of few tens and several hundreds of individuals (totally 65.6 %). Species with big populations represent far smaller part of forest rare species. Nine rare species grow in the number of several thousands of plants within the Park and three species (Allium ursinum, Galanthus nivalis and Leucojum vernum) – over a million. It has been established that 52.4 % of rare species populations taken together remain in critically bad state, 28.6 % of the populations – in bad state, 14.3 % – in satisfactory state. Only 4.8 % of populations are in good state. Our results show that about 95 % of species are in need of protection and continuous monitoring of population number. Furthermore, 51 species of rare plants,having low number and bad state of populations, require to work out and implement management plans for their restoration.
