ЗБЕРЕЖЕННЯ РІДКІСНИХ ЛІСОВИХ ВИДІВ СУДИННИХ РОСЛИН У СИСТЕМІ ПРИРОДООХОРОННИХ ЗАХОДІВ МЕЗИНСЬКОГО НАЦІОНАЛЬНОГО ПРИРОДНОГО ПАРКУ

The article characterizes the peculiarities of the formation of forest ecosystems as centers for the distribution of rare species within the territory of Mezyn National Nature Park. The research area is notable for its diverse ecotopic conditions, which support a wide variety of forest species of vascular plants and corresponding communities, including oak, linden-oak, maple-linden-oak, linden, and hornbeam-oak forests. The forest group of vascular plant flora in the territory of Mezynskyi NNP includes 18 species, with 10 species listed in the Red Data Book of Ukraine and 8 species having regional protection status in Chernihiv Oblast. Among the forest species from the Red Data Book of Ukraine, the non-moral group predominates, including Neottia nidus-avis, Listera ovata, Epipactis atrorubens, Epipactis helleborine, Platanthera bifolia, Platanthera chlorantha, Lilium martagon, and Allium ursinum. Among the species of vascular plants in forest ecosystems that are protected at the regional level in Chernihiv region, within the study area, 7 species of the division Polypodiophyta are distinguished, specifically: Dryopteris cristata, Gymnocarpium dryopteris, Matteuccia struthiopteris, Polypodium vulgare, Polystichum aculeatum, P. brauni, and Phegopteris connectilis. Anthropogenic impacts on the forest areas of Mezyn NNP, including on rare species of vascular plants, can be classified into the following groups: production and traditional economy, recreational activities, forestry activities and control measures, and violation of the protected area. The greatest impact of the recreational factor is on recreational forest areas and areas around settlements. The development of measures and plans for the protection of rare species will ensure the principles of protecting forest ecosystems as a whole (general) and their individual components (special). The article presents a system of environmental measures for the protection and conservation of rare forest species of vascular plants, and suggests measures for further conservation and monitoring of these species. To address the issues of conserving rare species, the article recommends optimizing the zoning system of the park territory, expanding the protected area, and including existing protected areas and habitats of rare flora species within its composition.

FLORA OF RARE VASCULAR PLANT SPECIES IN THE REGIONAL LANDSCAPE PARKS OF THE UKRAINIAN POLISSIA

The analysis of rare vascular plant types in the territories of regional landscape parks within the Ukrainian Polissia was carried out. The results of a systematic analysis of the flora of rare species of vascular plants on the territory of five regional landscape parks of the Polish part of Ukraine are presented, in particular: Pripyat-Stokhid, Nadsluchanskyi, Ptashiny Rai, Mizhrichenskyi, Yalivshchyna.According to the taxonomic structure, they belong to 199 species, 141 genera, and 64 families. It was found that the majority of regionally rare species are characterized by small areas of localities with a sporadic or scattered-diffuse spatial arrangement, a relatively low number of individuals. The conservation status of regionally rare plant species according to the IUCN categorization has been determined. According to it, established plant species belong to six categories of danger and are distributed as follows: CR (critically endangered species) – 1, EN (endangered species) – 22, VU (vulnerable species) – 32, NT (species approaching extinction) – 126, LC (a species requiring attention) – 14, DD (a species not sufficiently researched) – 4. The obtained research results will serve as a basis for ecological phytomonitoring and zoological management at the regional level.

Sustainable use of economically valuable and conservation of rare plant species in Almaty region

The paper contains the results of the initial cadastral survey and integrated assessment of the components of the flora (plant resources, higher plants and algae) of the Almaty region (2021–2023), which occupies a leading position among the economically developed regions of the country. The reserves of raw materials of 18 plant species demanded by the domestic pharmaceutical industry discovered on the territory of 13 administrative districts are of practical value. Eleven species of medicinal plants can be recommended for industrial harvesting. It is important to note that conservation efforts are required to protect 118 rare species of higher vascular plants and three species of lower plants, such as algae – indicating the vegetation’s current condition in the region. For the first time, the region’s list of rare flora species includes 13 species that have been categorized into IV categories based on the criteria and categories of the Red List of the International Union for Conservation of Nature. The results obtained will serve as a scientific basis for regular monitoring and forecasting of effective environmental activities that ensure the sustainable use and conservation of plant resources in the region.

Rare, protected, and understudied vascular plant species of the pinewood complex of the Mozh River valley (Kharkiv Region, Ukraine)

The composition of the biota is dynamic and changes for many reasons, making biodiversity research relevant. Studies of rare species that are most vulnerable to anthropogenic pressures are of particular importance. Although the Mozh River flows through the central part of the Kharkiv Region, its valley remains understudied, especially the pine forests and their rare plants. The results of the current study include data from our field research, revision of the Herbarium of V.N. Karazin Kharkiv National University (CWU), and literature sources from the second half of the 20th century to the present. This paper contains an annotated list of 35 species of vascular plants. Each species is provided with the data on its geographical range, distribution in Ukraine, population status and its study history in the Kharkiv Region, conservation status, and the state of its population in the studied forests. We found the localities of two species included in Appendix I of the Bern Convention (Salvinia natans (L.) All. and Jurinea cyanoides (L.) Rchb. and six species included in the Red Data Book of Ukraine (Botrychium lunaria (L.) Sw., Pulsatilla pratensis (L.) Mill., Iris pineticola Klok., Neottia nidus-avis (L.) Rich., Neottia ovata (L.) Hartm., Tulipa quercetorum Klok. & Zoz). We also found 19 species rare in the Kharkiv Region (Lycopodium clavatum L., Athyrium filix-femina (L.) Roth, Ophioglossum vulgatum L., Campanula persicifolia L., Chimaphila umbellata (L.) W.P.C. Barton, Comarum palustre L., Hottonia palustris L., Rubus saxatilis L., Carex pseudocyperus L., etc.). Nine regionally rare plant species have the boreal range type; they occur at the southern limit of their distribution range which indicates the specificity of ecological and climatic conditions formed in the pine forests in the Mozh River valley. In addition, we found five species without conservation status, but they are rare in the region (Caltha palustris L., Catolobus pendulus (L.) Al-Shehbaz, Gratiola officinalis L., Lythrum hyssopifolia L., Rubus polonicus Barr. ex Weston), and, therefore, they are recommended to be included in the next edition of the Official List of the Regionally Rare Plants of the Kharkiv Region. Three species (Buglossoides czernjajevii (Klokov & Des.-Shost.) Czerep., Jacobaea andrzejowskyi (Tzvelev) B.Nord. & Greuter, Sedum album L.) were identified as understudied in the Kharkiv region due to the lack of or insufficient information on their distribution in the study area.

The localities of numerous rare species of vascular plants are provided. Among them, it is species included in the Resolution № 4 of the Bern Convention (i.e. Thesium ebracteatum), the Red Data Book of Ukraine (i.e. Dactylorhiza incarnata, Fritillaria ruthenica, Gladiolus imbricatus, Glycyrrhiza glabra, Lilium martagon, Lunaria rediviva, Pulsatilla patens, Stipa pennata, Stipa tirsa) and regionally rare plants.

Rare phytodiversity of the Ivotka river basin within the territory of the Sumy region

The search and study of the distribution conditions of rare plants are important for their protection from extinction and the conservation of biodiversity. This activity becomes even more relevant due to the acceleration of climate change due to anthropogenic impact on biocenoses, in the formation of which plants play a substantial role, creating grass cover of meadows, floodplains, and undergrowth. The purpose of this study was to collect and analyse information on protected plant species and communities in the Ivotka river basin in the Sumy region and study the conditions of their distribution. In the course of the study, field examinations were conducted to search for rare plants and describe the places of their localisation using the route diagnostic method and desk studies to identify the found material. The result of the study was the finding of 28 rare species of vascular plants in the Ivotka river basin within the Sumy region, among which 2 are listed in Resolution No. 6 of the Berne Convention and the Red Book of Ukraine, 10 – in the Red Book of Ukraine, 16 – in the list of plant species that are not listed in the Red Book of Ukraine, but are rare or endangered in the territory of the Sumy region. These plants can be classified as especially valuable for conservation that require protection and balanced use of both these species and the biocenosis complex in their distribution territory. It is not enough to change the protected status of the plant species itself or the territory of their localisation to preserve and protect rare plants. Systematic implementation of responsible forest and land use practices is essential to preserve existing biodiversity. The results obtained help to establish the protected status for rare plants, develop measures for their protection and use, and determine the need to implement a system of responsible forest and land use for Biodiversity Conservation

Field observations and remote assessment identify climate change, recreation, invasive species, and livestock as top threats to critically imperiled rare plants in Nevada

IntroductionRare plant species comprise >36.5% of the world’s flora and disproportionately support ecosystem function and resilience. However, rare species also lead global plant extinctions, and unique ecological characteristics can make them vulnerable to anthropogenic pressure. Despite their vulnerability, many rare plants receive less monitoring than is needed to inform conservation efforts due to limited capacity for field surveys.MethodsWe used field observations and geospatial data to summarize how 128 imperiled, rare vascular plant species in Nevada are affected by various threats. We assessed correlations between threats predicted by geospatial data and threats observed on the ground and asked how historic and current threats compare.ResultsThe most commonly observed threats were from recreation, invasive and non-native/alien species, and livestock farming and ranching. Threat prevalence varied by elevation (e.g., a greater variety of threats at lower elevations, greater threat from climate change observed at higher elevations) and land management. There was a 28.1% overall correlation between predicted and observed threats, which was stronger for some threats (e.g., development of housing and urban areas, livestock farming and ranching) than others. All species experienced extreme climatic differences during 1990-2020 compared to baseline conditions, with the most extreme change in southern Nevada. The average number of threats observed per occurrence increased by 0.024 each decade.DiscussionWhile geospatial data did not perfectly predict observed threats, many of these occurrences have not been visited in over 30 years, and correlations may be stronger than we were able to detect here. Our approach can be used to help guide proactive monitoring, conservation, and research efforts for vulnerable species.

Флора города Брянска на платформе iNaturalist

The article discusses the current level of species diversity of the flora of the city of Bryansk, on the base of the iNaturalist platform. In the project «Flora of Bryansk» 942 species of vascular plants are registered. A critical analysis of the list of species was carried out, thr conclusions about the dynamics of the flora of the city were made. As a result, the studies flora of Bryansk discovered previously unknown locations of rare species of vascular plants, included in the Red Data Book of the Bryansk Region (Krasnaia..., 2016), and a list of species requiring additional observation and monitoring.

New and rare adventitious species of vascular plants in the Sverdlovsk Region

The article provides an information about the finds of six adventitious plant species in the Sverdlovsk Region, two of them are new to the flora of the region (Hesperis pycnotricha Borbás et Degen., Nepeta sibirica L.). Four species (Lotus corniculatus L., Silene dichotoma Ehrh., Urtica cannabina L., Vicia amoena Fisch.) were previously known from 1–2 localities in the Sverdlovsk Region and are rare adventitious species not only in the region, but also in adjacent territories. The presented information about new localities of adventitious species will become the basis for monitoring their distribution in the studied region in particular, and in the Urals as a whole.

Nature conservation significance of Plav-ІІ, Yamny peat ecosystems of Zhytomyr region

The materials of the Report on environmental impact assessment of peat extraction of the Plav-II deposit in the administrative boundaries of Olevskyi district of Zhytomyr region were analyzed. Nature conservation studies of peat ecosystems of Plav-II, Yamny have been carried out. We do not recommend the development of peat deposits. The territory of the planned activity (the southern section of the Yamny peat deposit) is partially located on the territory of the Emerald Slovechanskyi Kriazh (UA 0000173) facility. Among the animal species included in the Red Book of Ukraine, Lanius excubitor Linnaeus, 1758, Lyrurus tetrix Linnaeus, 1758 were recorded. In the last case, a hen with chicks was noted. This fact testifies to the importance of this locality for the reproduction of the species, since the hatching and hatching of the offspring in grouse takes place in the foci of their moulting in the spring. In addition to the mentioned species, the noted Crex crex Linnaeus, 1758 is a species included in Appendix II of the Berne Convention, ratified by Ukraine. For the first time, new habitats of six plant species listed in the Red Data Book of Ukraine were discovered: Carex chordorhiza Ehrh., Carex heleonastes Ehrh. Dactylorhiza incarnata (L.) Soó (Orchis incarnata L.), Utricularia intermedia Hayne, Salix lapponum L., Salix myrtilloides L. Noted regionally rare species of flora: Parnassia palustris L., Nymphaea candida C. Presl., Carexlimosa L. Monitoring such rare species of higher vascular plants as Andromeda polifolia L., Drosera rotundifolia L., Rhynchospora alba (L.) Vahl, etc. need research. Habitat types from resolutions of the Convention on the Conservation of Wild Flora and Fauna and Natural Habitats in Europe (Bern Convention): C1.222 Floating Hydrocharis morsusranae rafts — Hydrocharis morsus-ranae, D2.3 Transition mires and quaking bogs. One of the features of the flora and vegetation of the Plav-II tract is the absence of adventive, invasive plant species (with the exception of Aronia melanocarpa (Michx.) Elliott). On the other hand, on the drained Yamny peatland, phytoinvasions appear massively, but in comparison there is a much greater and sozologically important diversity of avifauna. It is recommended to create a reserve of local importance Plav-II, as well as justify rehabilitation and renaturalization measures in the Yamny peatland.

Analysis of rare vascular plant species in need of protection in wetlands of Republic of Bashkortostan

The work presents a systematic and phytosociological analysis of rare threatened vascular plants of the wetlands in the Republic of Bashkortostan. The work considers the plants listed in the Bern Convention list, Red Data Books of the Republic of Bashkortostan and the Russian Federation, as well as IUCN Red List of Threatened Species. In Bashkortostan, the greatest number of rare mire species is represented by the family Orchidaceae, and the second place belongs to the family Cyperaceae. The communities of low sedge-moss minerotrophic fens of the alliance Caricion davallianae and oligo-minerotrophic mires of the alliance Sphagno-Caricion canescentis are the richest in rare species. Less rich in rare species are mesotrophic paludified forests and shrublands with sedge-moss communities of the alliance Betulion pubescentis and oligotrophic shrub-sphagnum bogs of the alliance Vaccinio uliginosi-Pinion sylvestris. The communities of eutrophic mires dominated by high sedges, shrubs, trees, as well as water communities located within mire complexes have the lowest diversity of rare species.

VASCULAR PLANTS OF POLTAVA TOWN TERRITORIAL COMMUNE: AN ANNOTATED CHECKLIST

The paper summarized the data about vascular plant species of Poltava town territorial commune formed in 2020 during decentralization reform within Poltava district of Poltava region. Based on own field research in 2006–2021 authors found on this territory 996 vascular plant species from 105 families. They include 911 species from 432 genera and 101 families which are resident taxa and belong to a stable components of a plant cover on this territory; they grow a long time here and have a regular self-healing ability. The annotated list of resident plant species with main their synonymic Latin names is indicated. 85 species from 77 genera and 32 families have also been found on the research territory but they are not to be able to accept as a stable component of a plant cover since they are locally distributed, occasionally escaped from cultivation or alien and are not naturalized here.These species were included in the additional list indicated in this paper too; they need a monitoring research for their status and further distribution on this territory. It was established that the territory of Poltava town commune has a great species diversity of vascular plants: 63,3% of resident taxa which were found in the Left Bank Forest-Steppe of Ukraine and 73,9% of resident taxa found in Poltava region have been discovered by authors. The features of Poltava town commune are high participation (61 species or 6,1%) rare vascular plant species – 14 from «The Red Data Book of Ukraine» and 47 regionally rare plant species within Poltava administrative region, and rather low degree of preservation area (0,3%). So the priority task for the development of Poltava town territorial commune in a direction of a biodiversity conservation is to be creation of new preservation territories on areas with the high concentration of rare vascular plant species.
