A geobotanical survey of rich fens on the left-bank terraces of the Em-Egan River, the right tributary of the Malaya Sosva River in the southern part of the nature reserve “Malaya Sosva” (61.79° - 62.05° N, 64.06° - 64.55° E). 179 species have been identified, including 84 species of higher vascular plants, 69 species of mosses and 26 types of liverworts. Of these, 11 species are included in the Red Data Book of the Khanty-Mansi Autonomous District, including 9 species of higher vascular plants and 2 species of mosses: Baeothryon alpinum, Cardamine nymanii, Dactylorhiza traunsteineri, D. incarnata, Hammarbya paludosa, Huperzia selago, Saxifraga hirculus, Thelypteris palustris, Triglochin palustre, Meesia triquetra, Paludella squarrosa. Three more species – Corallorrhiza trifida, Calliergon richardsonii, Meesia uliginosa are included in the list of species whose condition in the natural environment requires special attention. In addition, such rare species as Eriophorum brachyantherum, Stellaria crassifolia, Bistorta major, rare species of mosses such as Bryum bimum, Calliergonella cuspidata, Campylium pretense, Hamatocaulis vernicosus, Scorpidium cossonii, Tomentypnum nitens are listed in the mire plant communities. On the basis of the ecological-floral approach of the J. Brown-Blanke school, 8 associations, 6 subassociations and 3 communities from 5 unions, 3 orders and 3 classes of vegetation were allocated in the vegetation cover of rich fens. The belonging of one more vegetation community type of the Bistorta major–Sphagnum fuscum dwarf birch community with the sparse fir (Picea obovata) to the class and the order is not established. The highest phytocenotic diversity and the highest concentration of rare and protected species are found in communities of the order Sphagno warnstorfii-Tomentypneetalia. Phytocenotic association and frequency of occurrence of rare species in different types of plant communities are established.

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.

Abstract The article is devoted to the research results concerning the flora of vascular plants of the Makarovsky Nature Reserve situated in the middle part of Sakhalin Island. Nowadays, 407 species of vascular plants have been identified on its territory, and 26.8 % of the total number of taxa known on the island. Among them, 13 species of rare plants included in the Red Data Book of the Sakhalin Region have been identified. The structure of the leading families and genera is indicated, the flora is analyzed by life forms, geographical elements and ecological-cenotic groups.

We analysed 10 rare-plant projects conducted from 1982 to 2005 for trends in scientific findings, project costs, effort and efficacy. Our purpose was to determine whether generalisations about these factors can be found, and if so, whether they might be useful for designing and implementing successful future rare-plant endeavours. Analysis results revealed that rare plant species persist despite their restriction to a highly fragmented and degraded urbanised estuary of more than seven million people. Also important were the findings that with sufficient funding, successful rare-plant reintroduction is possible in the short-term at minimum. Habitat considerations, however, are paramount—i.e. habitat requirements of a rare species should be known before reintroduction for the restoration effort to be likely to be successful. Understanding ecosystem functions that support rare species, therefore, remains the highest priority for rare-plant restorationists. Project costs varied significantly, as expected, but a ‘middle ground’ provides necessary and sufficient funding to conduct most rare-plant work for one or a few species. Costs rise, but not linearly, when additional rare taxa are included. Given our experience is applicable elsewhere, taking an ecosystem approach to protection of rare flora is most successful and cost effective.

The present-day demand for digital availability of distributional data in biodiversity studies requires a special effort in assembling and editing the data otherwise scattered in paper literature and herbarium collections, which can be poorly accessible or little understood to present-day users and especially automatic data processors. Our project on developing the information resource for the vascular plant flora of Murmansk Region, Russia, includes processing and making digitally available all the data on the taxonomy and distribution of this flora. So far, published distribution maps are limited to the old set in the Flora of Murmansk Region (published in 1953–1966) and the Red Data Book of Murmansk Region (ed. 2, published in 2014). These publications did not take into account the main part of the herbarium collections kept at the Kandalaksha Strict Nature Reserve, which are the basis for numerous local publications that appear scattered and, therefore, little accessible nowadays. We present a complete dataset of all holdings of vascular plants in the Herbarium of the Kandalaksha Strict Nature Reserve, totalling 10,218 specimens collected during 1947–2019, which are referable to 764 species and 19 subspecies. All specimens were georeferenced with the utmost precision available. This dataset offers a complete and dense coverage of the Nature Reserve's territory (islands and adjacent mainland coastal areas of the Barents and White Seas, Murmansk Region and Republic of Karelia, Russia); these data are little represented in herbarium collections elsewhere.

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.
