The issue of the conservation status of the species Cephalaria uralensis (Murr.) Schrad. ex Roem. et Schult. (Dipsacaceae Juss.) в) on the territory of the Republic of Bashkortostan is considered in the article. The species was included in the first edition (2001) and the second edition (2011) of the Red Data Book of the Republic of Bashkortostan (category and status: 3 – rare species, the species is located on the territory of the republic at the northern and eastern borders of the range). The article provides the following information about the species: morphological description with an indication of the main diagnostic features; modern data on the distribution of the species in the republic, new finds of the species in the Bashkir Cis-Ural и South Ural (western macroslope); brief ecological and phytocenotic characteristics; features of biology (according to data from literature sources); modern data on the number and state of local populations; limiting factors; adopted and recommended protection measures, data on the possibility of preserving the species in culture. The state of the species Cephalaria uralensis at the present time on the territory of the Republic of Bashkortostan can be considered satisfactory. The species shows significant resistance to adverse factors. It was found that the species is widespread in the republic much wider than previously thought. The species is satisfactorily provided with territorial protection, a significant part of its known populations are located within the boundaries of existing or projected specially protected natural areas. The data presented in the article substantiate the reasons for the exclusion of the species Cephalaria uralensis from the list of the Red Data Book of the Republic of Bashkortostan and its subsequent inclusion in the regional list of observed species – «List of flora and fungi that need special attention to their state in the natural environment and monitoring (observed species)» [Red Data Book..., 2021].

The issue of the conservation status of Euphorbia glareosa Pall. ex Bieb. (Euphorbiaceae Juss.) on the territory of the Republic of Bashkortostan is considered in the article. In the second edition of the Red Data Book of the Republic of Bashkortostan [2011] this species was included in the regional list of rare species that need biomonitoring – «List of objects of flora and fungi that are not included in the Red Data Book of the Republic of Bashkortostan, but need special attention on the territory of the republic to their state in the natural environment and monitoring». The article provides the following information about the species: morphological description with an indication of the main diagnostic features; modern data on the distribution of the species in the republic; brief ecological and phytocenotic characteristics; features of biology (according to data from literature sources); modern data on the number and state of local population; limiting factors; adopted and recommended protection measures, data on the possibility of preserving the species in culture. On the territory of the Republic of Bashkortostan, the species E. glareosa достоверно is known only from one point – the southern shore of Lake Aslikul in the Davlekanovsky district (the territory of the Asly-Kul natural park). In the republic, E. glareosa is a poorly studied species and is located at the edge of the range (at the eastern and northern limits of distribution). The known population is small 50-80 generative individuals). The population is subject to negative anthropogenic and natural influences. The species is poorly resistant to these influences. The species is on the verge of extinction. The data presented in the article fully justify the possibility of excluding the species Euphorbia glareosa Pall. ex Bieb. from the regional list of rare species «List of objects of flora and fungi that are not included in the Red Data Book of the Republic of Bashkortostan, but need special attention on the territory of the republic to their state in the natural environment and monitoring» and including it in «List of objects of flora and fungi listed in the Red Data Book of the Republic of Bashkortostan» (third edition, 2021) (category and status: 1 – endangered species).

The article presents a review of data on a rare endemic species of the flora of the Republic of Bashkortostan (RB) – Pimpinella tomiophylla (Woronow) Stank. (Apiaceae). The species is included in the third edition of the Red Data Book of the RB [2021] in the following status: category 2 – a species that is declining in abundance and/or distribution; vulnerable species (VU); II priority (Bashkir Cis-Urals). The article provides the following information about the species: conservation status; nomenclature reference; morphological description; distribution in the republic; brief ecological and phytocenotic characteristics; features of biology; modern data on condition of the local population; limiting factors; measures for the protection. The species was first described for science in 1931 from Mount Tratau (RB, Ishimbai district) according to herbarium collections in 1915 and 1926 (LE) [Voronov, 1931; Flora of the USSR, 1950]. In the republic, P. tomiophylla is a poorly studied species and is located within a narrow local range. At present, the species is reliably known only from one point – the territory of the natural monument «Mount Tratau» (UFA) [The Red Data Book…, 2021]. The species occurs in plant communities with typical petrophytic species. It grows mainly in the lower part of the western and southwestern slopes of the mountain. The known population of the species is numerous. In recent years, the recreational load on the populations of rare species on Mount Tratau, including the species P. tomiophylla, has increased, which will inevitably lead to a reduction in the area and number of its population. The necessity of a set of additional measures for the protection of P. tomiophylla in situ and ex situ is substantiated.

The Bashkir Trans-Urals (the eastern part of the Republic of Bashkortostan) includes the low mountains and foothills of the eastern slope of the Southern Urals, as well as the adjacent Sakmaro-Tanalyk and Kizilo-Urtazym plains. The vegetation is forest-steppe and steppe. Despite the small amount of precipitation (350-450 mm/year), there are quite a lot of mires, especially in the northern part of the study area. Mires are located mainly on the slopes of mountains and hills and at their foothills, in endorheic basins, in river floodplains, and often have a large area (up to several hundred hectares). All mires are eutrophic, their vegetation cover includes paludified birch and black alder forests and treeless reed, reed-sedge, moss-sedge plant communities. In 2023, more than 240 mires were identified in the Bashkir Trans-Urals, 60% of the total area of which (more than 8 thousand hectares) were disturbed as a result of drainage and peat extraction. There are very few publications about the distribution and the state of populations of rare plant species in the mires of the study area. The aim of this work is to summarize and to analyze the data on the representation of rare species of vascular plants in the mires of the Bashkir Trans-Urals. Currently, in the mires of the Bashkir Trans-Urals, 32 rare plant species in need of protection have been identified, including 25 species (Table 1) listed in core list of the Red Data Book of the Republic of Bashkortostan [Martynenko, 2021], as well as 7 species are included in the Appendix II to this book, i.e. “List of flora and fungi that require special attention to their condition in the natural environment and monitoring in the Republic of Bashkortostan” (Carex dioica, Ranunculus lingua, Salix myrtilloides, Salix pyrolifolia, Saussurea parviflora, Baeothryon pumilum, Utricularia intermedia). Two species (Liparis loeselii. and Orchis militaris) are included in the Red Data Book of the Russian Federation [Order ..., 2023]. The largest number of rare mire species belong to the families Orchidaceae (11 species) and Cyperaceae (4 species). About 80% of these rare species are stenotopic and have a fidelity score for the mire ecotope III-V. Therefore, the destruction or degradation of their habitats will lead to the disappearance of their local populations in the Bashkir Trans Urals. Little is known about the population size of rare species growing in the mires of the Bashkir Trans-Urals. Local populations of these species are often small and usually consist of several dozen, rarely hundreds of individuals (Carex serotina, Dactylorhiza russowii, etc.). For few species, for instance, Orchis militaris, the subpopulation size within the mire can amount to several thousand individuals, but, depending on weather conditions, there are extreme fluctuations in the number of plants in different years. A decrease in the number or disappearance of subpopulations of rare plant species depends on different factors, i.e., fluctuations in the water level in lakeside mires, the habitat degradation along the edges of mires due to grazing and haymaking (Artemisia laciniata), drying out of mires due to a decrease in the groundwater level after droughts (Liparis loeselii, Saxifraga hirculus), drainage, peat extraction, peat fires and recreation. Currently, populations of rare and protected species of vascular plants have been identified in 58 mires. The most valuable for the protection of rare species of vascular plants are the mire vegetation complexes of the natural monuments “Nurok Mire”, “Karpis Mire”, “Starobalbukovskoye Mire” [Muldashev et al., 2020]. Most of the mires of the Bashkir Trans-Urals, where habitats of rare species have been identified, do not have conservation status. Searching for new locations and monitoring local populations of rare plant species are a necessary for organizing effective protection of the biodiversity of this region, which is characterized by a high degree of agricultural development. Factors causing a reduction or disappearance of local populations of rare species in the mires of the Bashkir Trans-Urals are the consequences of drainage, fluctuations in the water level in lakeside mires, grazing and haymaking along the edges of mires, drought and recreation.

Monitoring of protected fungi species by methods of modern information technologies

The first unofficial edition of the “Red Book of the Bashkir ASSR” was published in 1984. This Red Book was very different in structure from modern editions and had no official status. 170 plant species were included in this Red Book. In 1987, it was reissued with minor changes. These editions aroused great interest in the scientific community and significantly stimulated the study of rare species. The first official edition of the Red Book of the Republic of Bashkortostan (RB) in the section “Plants and Fungi” was published in 2 volumes in 2001 and 2002. In the new edition, the list of taxa was significantly revised. About 70 species were excluded and about 100 new species were included. Adhering to the principle of unity of the Red Books of the Russian Federation and regions, a number of spe- cies that are generally rare for Russia, but common in the Republic of Bashkortostan, was included in the Red Book by force. In 2011 and 2021, the 2nd and 3rd official editions of the Red Books of the Republic of Bashkortostan were published, respectively. They critically revised the list composition, included 232 species each, of which only 88 species were included in the 1984 edition. In total, 347 species were included in all editions, which is about 16% of the entire flora of the Republic of Bashkortostan. The Red Books played a huge role in protecting the biodiversity of the republic. They stimulated compre- hensive studies of rare species in many scientific centers. In the conditions of the Botanical Garden, more than 80 species were covered by research, i.e. 30% of the total number of “Red Book” species of the Republic of Bashkortostan. More than 10 botanical and 60 complex natural monuments were created to protect “Red Book” species. The data from the Red Book were widely used in the development of the mapscheme “System of Protect- ed Natural Territories of the Republic of Bashkortostan”, approved by the Government of the Republic of Bash- kortostan in 2004. Since 2002, an annual summary “Maintenance of the Cadastre of Rare and Endangered Species of Higher Vascular Plants of the Republic of Bashkortostan” has been compiled, the materials of which are used for the re- publication of the Red Book.

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.

Growing anthropogenic pressure and changing climate conditions create new reality in which more and more native fauna species require our attention. That is the reason for scientists to compile Red Lists or Red Data Books on different levels. The main factors of negative impact on animals nowadays are as follows: destruction and/or transformation of natural ecosystems (habitats), illegal removal from nature, commercial overuse, natural disasters and climate change, as well as military actions. The Red Data Book of Ukraine includes 140 species of animals which appear in Lviv region. However, there are also other species within the region that deserve protection. The latest Lviv region list of rare species was approved in 2007 – two years before the publication of the third edition of Red Data Book of Ukraine, and is somewhat outdated. For more than 15 years the animal habitats have changed, and the list of species in the new edition of the Red Data Book of Ukraine (2021) has changed significantly. According to this, a new list of regionally rare animal species is objectively needed. Such a list has been compiled and is presented in the article. The main species criteria for being included into it are: vulnerability to the environmental changes, a sharp decline in the number of individuals or rapid population area shrinkage, low occurrence frequency within the region, relic origin, endemic or sub-endemic status, species on the edge of their distribution ranges or with the complex life cycles, etc. We believe that our knowledge about regionally rare species and their distribution can be one of the reasons for the establishing of new protected areas. This will help to preserve rare ecosystems in the structure of national ecological network and strengthen the conservation of species and coenotic diversity both in some separate territories or regions, and in Ukraine as a whole. After additional, detailed scientific research some of the regionally rare animal species will obviously be recommended to be included into the next edition of the Red Data Book of Ukraine. Thus, at least 106 animal species are proposed to became regionally protected in Lviv region. 64 of them are already under the protection of Bern Convention, 26 – under Bonn Convention, and 13 under the protection of Washington Convention.

We began a targeted study of the entomofauna of the Chelyabinsk and Kashtak forests in 2007, and in the period from 2010 to 2023 were carried out regularly from spring (May) to autumn (September), annually performing from 5 to 10 expedition trips. In addition, after the publication in 2017 of the second edition of the Red Data Book of the Chelyabinsk Region, we also conducted annual monitoring of the status of populations of protected, rare, and vulnerable species throughout the region. The purpose of this work is to highlight the main results of the study of protected, rare and some little-known insects living in the territories of the natural monuments «Chelyabinsk (urban) forest» and «Kashtaksky forest». The material was collected along regular routes and key areas, including water bodies (streams, rivers, ponds, temporary reservoirs) and coastal biotopes. The length of the routes, depending on weather conditions and specific tasks, ranged from 3 to 15 km. They covered almost all the most typical types of communities, incl. partially transformed by man. We used manual collection, catching using a mowing net, air and water entomological nets. The abundance was determined by adults by direct counting the number of individuals per unit area (within 1 hectare) or count strip. 18 regional Red Data Book species have been identified, belonging to 10 families and 6 orders: in the Chelyabinsk forest there are 12 species from 9 families and 6 orders, in the Kashtak forest there are 11 species from 7 families and 4 orders. These are three species of status category II (declining in numbers) – Anax imperator, Bombus maculidorsis, B. pratorum, 14 species of status category III (rare) – Ophiogomphus cecilia, Leucorhynia caudalis, Sago pedo, Ranatra linearis, Parnassius apollo, Bombus distinquendus, B. hypnorum, B. lucorum, B. muscorum, B. serrisquama, B. terrestris, B. veteranus, Megachila rotundata, Bombylius major and one species of status category IV (uncertain status) – Laphria gibbosa. We classified 26 species from 15 families and 7 orders as rare and little-known (little studied). We consider Anas parthenope, Aeschna isosceles, Decticus verrucivorus, Meloe proscarabaeus, Iphiclides podalirius, Pieris brassicae, Glaucopsyche alexis, Apatura iris, Limenitis camilla, L. populi, Euphydryas maturna, Vanessa atalanta, Aglia tau, Oeneis tarpeja, rare. Megarhyssa perlata, Rhyssa persuasoria, Conops flavifrons. Little-known species, the biology and ecology of which have not been sufficiently studied (not only in forest conditions) are Libellula fulva, Sympetrum pedemontanum, Scaphidium quadrimaculatum, Ostoma ferruginea, Peltis grossa, Raphidia ophiopsis, Coenonympha hero. The only possible inhabitants of the Chelyabinsk Forest are the Chazara briseis and the Coenonympha oedippus, but this seems doubtful. A considerable number of «Red Data Book» species indicates that today, despite experiencing significant anthropogenic impact, our forests are still reserves of biodiversity and provide the necessary conditions for life even for species included in the Red Data Book of the Russian Federation (2021): Anax imperator (category 5), Saga pedo (category 2), Parnassius apollo (category 2). Seven species living in forests are also protected in regions neighboring the Chelyabinsk region – in the Republic of Bashkortostan (3 species), Kurgan (6), Orenburg (2), Sverdlovsk (3) regions.

Various types of forest and meadow plant communities of the Kabardino-Balkar Republic (CentralCaucasus) from the steppes to the alpine were examined by the route method during floristic investigations in 2018–2019. New locations of five rare species of vascular plants of the region natural flora were found (Picea orientalis (L.)Peterm., Taxus baccata L., Betula raddeana Trautv., Acer trautvetteri Medw., Eriophorum angustifolium Honck.). Exactlocations for another five rare species within the previously designated areas were also identified (Pojarkovia pojarkovae(Schischk.) Greuter., Scopolia carniolica Jacq., Hypericum nummularioides Trautv., Securigera orientalis(Mill.) Lassen,Galanthus alpinus Sosn.). The article presents the data on the floristic finds, indicating the coordinates of specific locations,species habitat preferences in region, the number of populations, the species distribution in the Caucasus, and informationof inclusion in the Red Books of adjacent regions. The rarest vascular plant species for the native flora of the KabardinoBalkar Republic are Galanthus alpinus, Scopolia carniolica, Pojarkovia pojarkovae. All three species were revealed inmountain territories subject to high recreational (trampling by tourists, picking up flowers) and economic (grazing) loads.All three species were revealed in mountain territories. The findings of isolated populations of Picea orientalis, Taxus baccata, Betula raddeana, Acer trautvetteri provided new information about the distribution and ecology of these rarespecies listed in the latest edition of regional Red Data Book. For these species, the categories of rarity status acceptedin the Red Book of the Kabardino-Balkar Republic are confirmed. Galanthus alpinus, Scopolia carniolica, Pojarkoviapojarkovae, Hypericum nummularioides, Securigera orientalis, Eriophorum angustifolium are proposed for inclusion inthe next edition of the Kabardino-Balkar Red Data Book. The most endangered state was identified for Picea orientalis,for which only two habitats in the region are reliably known and those are subject to intense anthropogenic impact.

The mycobiota of Tomsk oblast have been studied for many years on the basis of traditional and modern methods of systematics, biomorphology and molecular biology. Only such approach provides revealing background, and species of regional mycobiota. Basing on the results of 13-year investigations in 2004-2016 and on literature data, we extended the list of macromycetes of Tomsk oblast from 900 to 1300 species (subdivision Pezizomycotina and classis Agaricomycetes). For the stationary work in pine and cedar forests of Tomsk oblast we formed 7 long-term permanent transects with the total area of 1400 m 2 , where we collected and registered macromycetes every 10-15 days during the season. Several species were identified by Blast-N on line of the algorithm of comparing homologous sequences of ITS-region of nuclear DNA ribosomal genes in databases GenBank and BOLD. To amplify ITS1-5.8S-ITS2 region we used primer ITS1F common for fungi and primer ITS4B specific for basidiomycetes. We applied the scale of categories of rarity given in the Red Data Book of Tomsk oblast. Inclusion of a species into the group was based on an expert evaluation where key factors were its occurrence (up to 10 finds in the region during the whole period of investigations), reduction in the number as a result of a negative anthropogenic influence, and an analysis of the species occurrence by regional literature sources and by the Red Data Books of adjacent territories. As a result, 192 species were registered under natural conditions and 47 - under anthropogenic ones (in total 18.4% of the regional mycobiota) and are referred to as rare. We analyzed rare species, identified by mycologists in the 1980s (20 species); 11 of them have remained and endangered (See Tables). Four species are of the utmost concern today: Gyromitra sphaerospora (Peck) Sacc.; Phallus impudicus L.; Gyromitra gigas (Krombh.) Cooke and Sparassis crispa (Wulfen) Fr.; the last facts about them were provided in scientific literature in Tomsk oblast more than 30 years ago. Other 9 species were, on the contrary, transferred to the group; with a systematic monitoring they are regularly found in their typical habitats. For 192 presented rare species, the number of their registrations in Tomsk oblast and an overview of their conservation status in some regions of Siberia and European Russia are provided. In order to protect the regional mycobiota, we suggest establishing Specially Protected Natural Areas of different status in intact undisturbed forests and studying the mycobiota in already existing nature reserves. At the present time, this is particularly true for a fungal component of forest ecosystems of Siberia. An expansion of the list of protected species in the region seems important. E.g. in the 1 st edition of the Red Data Book of Tomsk oblast (2002) only 2 species of macromycetes and in the 2 nd (2013) - 8 species were presented; this does not correspond to the real situation and modern data on the species diversity of fungi and their status of rare and disappearing species.

The paper summarizes the results of the analysis of the territorial protection maintenance of the wildlife species listed in the Red Data Book of the Nizhny Novgorod region. To assess the current state of territorial protection of rare wildlife species the database containing 3599 facts of registrations of the rare wildlife species on approved and projected protected areas of the Nizhny Novgorod region was compiled by the authors. In addition, authors have offered to recognize 5 levels of the protection maintenance: full, good, satisfactory, poor, and absent. Authors have evaluated the scale of changes in the rare wildlife species providing with territorial protection in the XX-XXI centuries as well. The territorial protection maintenance of the rare wildlife species in the Nizhny Novgorod region has grown significantly over the past 40 years. In 2001, the rare wildlife species listed in the Red Data Book of the Nizhny Novgorod region were known to inhabit only 195 protected areas. Now the rare species of animals, plants, fungi and lichens are protected in 227 approved protected areas, and 92 territories are projected for the protected areas establishing. In general, the territorial protection of rare species listed in the regional Red Data Book seems to be satisfactory, but need the significant improvement. It is necessary to create additional protected areas along with continued searching of rare species habitats.

The article presents a review of data on the rare Pleistocene relict species of the Siberian origin of the flora of the South Ural – Gentiana decumbens L. fil. (Gentianaceae Juss.). The species is included in the third edition of the Red Data Book of the Republic of Bashkortostan (RB) [2021] in the conservation status: category 2 – a species that is declining in abundance and/or distribution; vulnerable species (VU); II priority (Bashkir Trans-Urals). In the RB there is an isolated relict fragment of the range of G. decumbens on the eastern slope of the Southen Urals – in the Baymak district. Currently, 10 locations of the species are known. The known populations of the species are small, fragmented, which makes the species vulnerable. Populations are subject to negative anthropogenic and natural influences, to which the species is weakly resistant. Only one population of G. decumbens has territorial protection, which is located within the limits of the botanical natural monument "The population of Allium hymenorhizum near Bogachevo village" in the Baymak district. The necessity of a set of additional measures for the protection of G. decumbens in situ and ex situ is substantiated.

<p>Urbanization is one of the most characteristic features of scientific and technological progress, which is associated with the rapid growth of cities and the urban population. It leads to irreversible processes of transformation of the natural environment. It anthropogenic transformation in connection with the development of the city and the subsequent rapid urbanization deals a devastating blow to the remnants of natural fractions urbanflora, which is preserved in the vicinity of Genichesk and would threaten the survival of a number of rare species of plants that grow here only in small areas with a small number of individuals.</p> <p>The article studies the protected and rare species of plants growing in the urban environment Genichesk. The study was conducted by routing way, with the implementation of standard procedures for drying, installation and post-processing of herbarium specimens. The research resulted in found new habitats of species listed in the Red Book, such as <em>Astragalus borysthenicus</em> Klokov, <em>Crambe maritima</em> L., <em>Tulipa gesneriana </em>L., <em>Astrodaucus littoralis</em> (M. Bieb.) Drude, <em>Stipa ucrainica</em> P. Smirn., <em>Tamarix gracillis </em>Willd. Also in the article provides a brief description of 11 species of vascular plants and their sozological value.</p> <p>Saving the plants, which listed in the Red Book of Ukraine, in the city Genichesk, is a difficult task. The main limiting factors are destruction of habitat, degradation of soil cover. As a result of anthropogenic activities, cultivation, creation of pastures and destruction of natural habitats are declining habitat and abundance of rare and endemic species. Collect flowers for bouquets also reduces the number of rare species. Every year in the spring on the outskirts of the city lit dry grass, which adversely affects the early-flowering plants, including rare, such as <em>Tulipa gesneriana </em>L.<em>, </em><em>Adonis vernalis </em>L.<em>, </em><em>Convallia majalis L</em>. Despite this, a significant number of these plants not only grows urboecotope but also successfully propagates in these conditions. Results of the study show that in the city of Genichesk currently stored favourable living conditions for some protected species, including seven species of Red Book and four species are protected at the level of regional lists. But due to human activity remains a risk of extinction of rare species of Red Book and that requires further monitoring and control of the state of their abundance and distribution in the city, as well as measures to protect their habitats.</p> <p><em>Key words: rare species, Red Book, urbanflora, Genichesk.</em></p><p><a href="http://dx.doi.org/10.7905/bbmspu.v5i1.966"><strong>http</strong><strong>://</strong><strong>dx</strong><strong>.</strong><strong>doi</strong><strong>.</strong><strong>org</strong><strong>/10.7905/</strong><strong>bbmspu</strong><strong>.</strong><strong>v</strong><strong>5</strong><strong>i</strong><strong>1.966</strong></a><strong></strong></p>

Insects, as the most diverse group of invertebrates, are often unfairly underrepresented in Red Lists of threatened taxa. Despite the significant biodiversity and ecosystem functionality of this group, regional Red lists of taxa often ignore truly threatened species and, conversely, include species that are quite common in adjacent regions. The paper presents the results of long-term monitoring of rare insect species in 14 regions of European Russia (Vladimir Region, Volgograd Region, Voronezh Region, Lipetsk Region, Moscow Region, Nizhny Novgorod Region, Penza Region, Ryazan Region, Republic of Mordovia, Republic of Tatarstan, Samara Region, Saratov Region, Tambov Region, Ulyanovsk Region). The aim of the study was to summarise the results of long-term research of rare species listed in regional Red Data Books and the Red Data Book of the Russian Federation. A wide variety of insect collection and census methods were used. To characterise regional Red Data Books during the research, the taxonomic lists, which were actual at the time of the research, were used. The information resulted in 96 insect species from eight orders (one from Odonata, three from Orthoptera, seven from Hemiptera, 64 from Coleoptera, two from Neuroptera, one from Raphidioptera, 13 from Lepidoptera, 5 from Hymenoptera), included in the Red Data Books of the studied regions; of these, 18 species are also included or were included in the recent (2021) or previous (2001) edition of the Red Data Book of the Russian Federation, respectively. Between one and three species listed in the Red Data Book of the Russian Federation were recorded for the first time in seven regions. The number of species included in the regional Red Data Books ranges from 47 species in the Volgograd Region to 261 species in the Voronezh Region. It is assumed that 30 species from the studied taxa do not require special protection measures and should be excluded from protected lists of regional Red Data Books. Justification for such recommendations is provided in each specific case. Leptura aurulenta is proposed to be included on the list of the Red Data Book of the Russian Federation.
