MEDICINAL PLANTS IN THE DENDROLOGY COLLECTION OF THE BOTANICAL GARDEN OF ONU IN THE EDUCATIONAL PROGRAM "PHARMACY"

Introduction. The quality of educational results in pharmaceutical botany in Ukraine is insufficient. This is evidenced by the results of the first stage of the Unified state qualification exam “KROK‑1” (“STEP 1”) in recent years. The improvement of the quality of education will be facilitated by the compilation of a clear list of types of medicinal plants, which applicants must study, and the acquaintance of future pharmacists with live plants stored in collections, in particular, the botanical garden of Odesa University. Aim. The purpose of the work was to identify and characterize a part of the dendrological collection of the open ground in the arboretum of the National University Botanical Garden, important for studying in the course of pharmaceutical botany by students of the second (master’s) level of education within the OPP «Pharmacy». Methods. For the first time, the dendrological collection of the open soil of the botanical garden was investigated for species used in scientific medicine. In order to identify the latter, the program recommended by the Ministry of Health, basic textbooks on pharmaceutical botany, pharmacognosy, the state register of medicinal products of Ukraine, the 2nd edition of the State Pharmacopoeia of Ukraine were analyzed. The analysis of the species list was carried out according to traditional floristic methods. Main results. In the dendrological collection of the botanical garden, 123 species from 42 families and 87 genera were found, which are considered in the textbook on pharmaceutical botany. Among them, the leading families are Rosaceae, Pinaceae, and Cupressaceae. Among life forms, trees dominate, with bushes being 2.3 times less frequent. Plants from the Circumboreal, Mediterranean and Irano-Turanian floristic regions predominate. Four species are listed in the Red Book of Ukraine (Juniperus excelsa, J. foetidissima, Sorbus aucuparia, Taxus baccata) and 8 require protection on the global scale (Abies numidica, A. pinsapo, Aesculus hippocastanum, Cedrus atlantica, C. libani, Eucommia ulmoides, Ginkgo biloba, Sequoiadendron giganteum), two are close to them (Platycladus orientalis, Pistacia vera). More than half of these species are used in scientific medicine. There are 72 species (11 gymnosperms and 61 angiosperms) from 58 genera and 34 families which are studied under the OPP «Pharmacy». Trees also predominate among them, but the numberof trees is only 1.6 times higher than of bushes. Among them there is 1 species from the Red Book and 6 species that are under threat of extinction on the global scale. The woody plants diversity is higher on the old territory of the botanical garden than on the new one. Zhakkar’s coefficient is 0.64. Official woody plants were identified, which are not in the collection of the botanical garden, but can grow here in accordance with the requirements for the surrounding environment. 17 species are proposed to expand the collection in order to more fully meet the educational needs of students of higher education in the specialty «Pharmacy».

Study of population and conservation of Dendrobium capra J.J. Smith, an endangered and endemic orchid from Java Island, Indonesia

Various plant species on Java Island are facing the threat of extinction. Dendrobium capra is an endemic orchid from East Java designated as a species with endangered status. This study aims to determine the distribution, population status, and microclimate conditions and update the conservation status of D. capra using the IUCN Red List Category and Criteria. The current population size, structure, distribution, and habitat preferences are presented. This study also investigates the phenology of D. capra for the propagation program and contributes to the latest updates on D. capra populations in their natural habitat. D. capra has an Area of Occupancy (AOO) value of 7.00 km2. These values meet criterion B (AOO < 10 km2), and D. capra is not found in conservation areas and has a very high risk of extinction in the wild. With only found in Bojonegoro regency, this study proposes assessing D. capra as a Critically Endangered (CR). The orchid has been conserved as a part of ex-situ collections in the Purwodadi Botanic Garden.

Holobiont responses of mesophotic precious red coral Corallium rubrum to thermal anomalies

Marine heat waves (MHWs) have increased in frequency and intensity worldwide, causing mass mortality of benthic organisms and loss of biodiversity in shallow waters. The Mediterranean Sea is no exception, with shallow populations of habitat-forming octocorals facing the threat of local extinction. The mesophotic zone, which is less affected by MHWs, may be of ecological importance in conservation strategies for these species. However, our understanding of the response of mesophotic octocoral holobionts to changes in seawater temperature remains limited. To address this knowledge gap, we conducted a study on an iconic Mediterranean octocoral, the red coral Corallium rubrum sampled at 60 m depth and 15 °C. We exposed the colonies to temperatures they occasionally experience (18 °C) and temperatures that could occur at the end of the century if global warming continues (21 °C). We also tested their response to extremely cold and warm temperatures (12 °C and 24 °C). Our results show a high tolerance of C. rubrum to a two-month long exposure to temperatures ranging from 12 to 21 °C as no colony showed signs of tissue loss, reduced feeding ability, stress-induced gene expression, or disruption of host-bacterial symbioses. At 24 °C, however, we measured a sharp decrease in the relative abundance of Spirochaetaceae, which are the predominant bacterial symbionts under healthy conditions, along with a relative increase in Vibrionaceae. Tissue loss and overexpression of the tumor necrosis factor receptor 1 gene were also observed after two weeks of exposure. In light of ongoing global warming, our study helps predict the consequences of MHWs on mesophotic coralligenous reefs and the biodiversity that depends on them.

Application of SWAT and WEAP Models for Sustainable Management of Water Resources in the Two Rivers Dam Catchment, Uasin Gishu County, Kenya

Kaptagat Forest, the main source of the Ellegerini River, which feeds the Ellegerini Dam and Two Rivers Dam, is under threat of extinction due to human activity. The Two Rivers Dam catchment that has over the years been a source of water in Uasin Gishu County is slowly depleting and urgent measures are required to restore it. Activities including commercial logging, charcoal burning and firewood harvesting have exerted a lot of pressure on the catchment, posing a great threat to the livelihoods of the people of Eldoret town who depend on the reservoirs for water supply. The main objective of this study was to customise SWAT and WEAP models for the sustainable management of water resources in the Two Rivers Dam catchment. The specific objectives were to set up and apply the SWAT model to generate simulated river flows draining to the Two Rivers and Ellegerini Reservoirs as an input to the WEAP model to determine the impact of land use change on the hydrological function of the Two Rivers Dam catchment, to set up, calibrate and validate a WEAP model for the Two Rivers Dam catchment and to apply the WEAP model in analyses of various management and infrastructural development projects scenarios to enhance river flow and water storage in the Two Rivers and Ellegerini Reservoirs. The goodness of fit SWAT model statistical evaluation indices attained during the calibration period was R2 = 0.854, NSE = 0.822 and Bias = 0.392. Additionally, for the validation period, the R2 = 0.786, NSE = 0.815 and Bias = 0.381. The modelled results indicate that the land use change resulted in decreased baseflow and increased surface runoff hence the high fluctuations of water levels in the Two Rivers and Ellegerini reservoirs. The WEAP model results for actual and simulated water demand in the calibration period of 2019, the R2 = 0.88, while during the validation period in the year 2020, the R2 = 0.85. The results of the model simulation indicated that the management option that had the most impact on all the scenarios was the reduction of unaccounted-for water, while the one with the least impact was increased water use efficiency. It was concluded that the models were able to simulate the observed conditions reasonably well and can therefore be used to effectively manage water resources and assist the relevant stakeholders in decision-making. The study recommended that forested areas need to be properly conserved in order to restore the hydrological function of the catchment.

Metz’s Relational Moral Theory and Environmental Ethics

Abstract Metz’s contribution to environmental ethics is a novel theory of moral status, which he argues explains the intuition that although we have direct moral duties to some nonhuman animals, our duties to fellow human beings are always weightier. The theory takes the moral status of an individual to depend on it being the subject and object of friendly relations with human. This paper argues that the account of moral status explains the intuition about the existence and relative weight of duties to nonhuman animals only if evidence of human-nonhuman animal cooperation is ignored. The paper argues additionally that a focus on the moral status of individual nonhuman animals offers no insight into one the most pressing environmental problems of our time, the threat of mass species extinction. Finally, the duties that would seem to follow from the account of moral status are contrary a traditional environmental concern of nature preservation.

Re-validation of biochemophysical variables as metrics for assessing the ecological integrity of an aquatic ecosystem (Badagry Lagoon, Lagos, Nigeria)

Assessment of ecological integrity of aquatic ecosystem is a major priority for scientists, government and private concerns all-over the world. In this study, multi-metric indices (physico-chemistry, biodiversity, length–weight relationship and condition factor) was used to evaluate the ecological integrity of Badagry Lagoon, Lagos, Nigeria. Three sampling sites (Akarakumo, Topo and Ajido) were selected based on extent of fishing activities. Water and fish samples were collected monthly from the three sampling stations for ten consecutive months (February to November, 2018). Standard methods were used for the analysis of physico-chemical parameters, fish diversity, length–weight relationship and condition factor of some fish species from the study sites. Simpson’s dominance index (0.056–0.057) and Shannon diversity index (3.11–3.13) were similar for the three sampling stations. The initial growth coefficient (a) in this study varied within a very narrow range (0.01–0.04) while the growth coefficient (b) had wider range (2.14–3.16). Growth pattern was predominantly negative allometry. Most of the fish species encountered were not under threat of extinction except Sarotherodon melanotheron and Sarotherodon galilaeus that were critically endangered and vulnerable, respectively. The physico-chemical variables of the sampling stations indicated that the ecological integrity of the water body is high, and this was corroborated by the results of biodiversity study, length–weight relationship and condition factors. Therefore, these metrics can be used in the assessment of the ecological integrity of aquatics.

Endangered Transsylvanian wingless groundhopper (Tetrix transsylvanica) is not extinct in Croatia and requires urgent protection

The Transsylvanian wingless groundhopper, Tetrix transsylvanica (Bazyluk et Kis, 1960) is a flightless pygmy grasshopper (Orthoptera: Tetrigidae) known only from a few fragmented localities and thus considered an endangered (EN) species in the IUCN Red List. The species consists of two subspecies, the nominal T. t. transsylvanica inhabiting the southern Carpathians in Romania, and T. transsylvanica hypsocorypha Skejo, 2014, until now known from a single locality in Slovenia (Mt Boč) and a single locality in Croatia where it was caught last time in the 1940s in Hrvatsko Zagorje (Gornja Pačetina, Trnovec). It is possible that the two subspecies represent separate species. The species has been considered extinct in Croatia. In this paper, we report the discovery of several subpopulations in Croatia, the largest one being at Siljevec on Ivanščica mountain. In addition, small subpopulations are reported on three other mountains (Strahinjčica, Medvednica and Zelinska gora), and two of them are suspected to be under threat of extinction: the subpopulation on the peak of Medvednica, Sljeme, and the subpopulation on Strahinjčica. The latter was discovered in a proximity of a quarry. The species is a (Pleistocene) relic and may be the only groundhopper endemic to Central Europe. Herewith, we appeal for its inclusion in the Ordinance on Strictly Protected Species of the Republic of Croatia, and for T. transsylvanica to be proposed as a candidate for the list of species protected through the Habitats Directive.

Pengaruh Eksistensi Bahasa Lampung Terhadap Pengembangan Pariwisata Di Kabupaten Lampung Barat

Current conditions in Indonesia, of the 617 identified regional languages, 15 regional languages ​​are declared extinct and 139 others are in endangered status. Information on the threat of extinction of regional languages ​​was stated by Dadang Sunendar as Head of the Language Development and Development Agency of the Ministry of Education and Culture through his research results, after attending the Nusantara Regional Language Congress at the Merdeka building, Bandung in 2016 (Permata and Abidin, 2020). This study aims to determine the effect of the existence of the Lampung language on tourism development in West Lampung Regency. The method used in collecting data in this study is descriptive. In this study, the descriptive method was used to identify and describe tourism development in West Lampung Regency. The data collection instrument used a literature study by collecting and studying several references through documents such as regulations, as well as book and journal references related to the Lampung language and tourism development in West Lampung Regency. Based on the results of this study, the introduction of the existence of the Lampung language can be a trigger for teenagers to use the Lampung language again in their daily lives and feel proud to introduce it to tourists in West Lampung Regency. In addition, the existence of the Lampung language can be used as an evaluation in areas that have similar problems and can introduce various cultures through local languages.

Development of an In vitro Propagation Protocol for Thalictrum foliolosum: An Endangered Medicinal Plant

The present study has developed a reproducible in vitro micropropagation protocol for endemic and endangered Thalictrum foliolosum by using leaf and root segments. Thalictrum foliolosum possesses high medicinal properties due to the presence of valuable phenols, flavonoids and alkaloids. The plants are uprooted due to their high medicinal and clinical applications, hence can lead to extinction threat. In vitro leaf and root, explant was used for induction of multiple shoots on MS medium supplemented with plant growth regulators like benzyl amino purine(BAP), indole-3- butyric acid (IBA), 1-Naphthalene acetic acid (NAA) and indole-3-acetic acid (IAA) alone or in combination. The best positive response for the formation of shoots from the leaf segment was obtained from MS media supplemented with BAP (1.0 mg/l) + NAA (0.6 mg/l) after 4 weeks and Maximum roots were formed on MS + IBA (0.6 mg/l) within 4-5 weeks. Likewise, the maximum percentage of shooting and rooting from root explant was obtained in MS + BAP (0.8 mg/l) + TDZ (0.4 mg/l) and MS + IAA (1.0 mg/l) + NAA (2.0 mg/l) after 4 weeks. The well-rooted acclimatized plantlets were successfully transferred to field conditions. Plant Tissue Cult. &amp; Biotech. 33(1): 47-56, 2023 (June)

Protected areas and the ranges of threatened species: Towards the EU Biodiversity Strategy 2030

Despite the protected area expansion over the last decades, biodiversity continues to decline. The EU Biodiversity Strategy for 2030, as well as the Kunming-Montreal Global Biodiversity Framework, call for 30 % coverage by protected areas of the land and sea in order to halt and reverse biodiversity loss. Here, we use European species assessed as threatened on the IUCN Red List – the ones facing the most imminent threat of extinction - to guide the proposed expansion. We overlapped the ranges of 2290 threatened terrestrial and freshwater resident species and 127,046 terrestrial protected areas (28,130 Natura2000 sites and 98,916 nationally designated protected areas) in the EU and we found that species' EU ranges are covered on average 49.6 % by protected areas (41.5 % by Natura2000 and 34.0 % by nationally designated protected areas). We found 71 Gap0.1 species (<0.1 % coverage), most of which are invertebrates and endemic to southern EU islands. The southern EU countries have the highest number of threatened endemic species, they offer among the highest coverage to threatened species ranges and they have almost reached the 30 % land coverage by protected areas. Therefore, the expansion of the protected area network, should not be guided solely by percentage of area targets, but instead by biodiversity needs. Although it should not be the only approach, targeting the protected area expansion towards Gap0.1 threatened species, would strengthen the EU protected area network by maximising the ability to conserve biodiversity and prevent extinctions.

Mammalian Roadkill in a Semi-Arid Region of Brazil: Species, Landscape Patterns, Seasonality, and Hotspots

Roadkill is one of the principal causes of the loss of biodiversity around the world. The effects of roads on mammals are still poorly understood in regions with a semi-arid climate, where many knowledge gaps persist. The present study provides an inventory of the mammalian species affected on highways in northeastern Brazil, as well as identifying roadkill hotspots and contributing to the understanding of how seasonality and the landscape may influence the roadkill patterns of wild mammals. A total of 6192.52 km of road were sampled in 53 field surveys conducted between 2013 and 2017. Landsat 8 satellite images and data from the MapBiomas platform were used to classify land use and cover for analysis. Buffers of 1 km, 5 km, and 10 km were created around the study roads to identify the landscape variables associated with roadkill events. Ripley’s 2D K-Statistics and the 2D HotSpot test were used to identify roadkill aggregations and hotspots; GLMMs were generated for the landscape variables and evaluated using the Akaike Information Criterion. The Kruskal–Wallis test was applied to investigate the potential effects of seasonality. A total of 527 wild animal carcasses were recorded as a result of vehicular collision. The species with the highest roadkill records were Cerdocyon thous, Euphractus sexcinctus, and Procyon cancrivorus, while two species—Leopardus emiliae and Herpailurus yagouaroundi—are considered to be under threat of extinction. For mammals in general, the best GLMM indicated an increase in roadkills with increasing density of local vegetation areas, and a decrease as urban areas increased. The model also found that the mammals were less impacted in the vicinity of a protected area. In the specific case of C. thous, the roadkill rate was lower when urban infrastructure was more common than dense vegetation; the rate increased as areas of dense vegetation increased. In the case of P. cancrivorus and E. sexcinctus, the best models of roadkill patterns included an area of exposed soil and sparse vegetation, respectively. Roadkill rates were higher in the rainy season for all the mammals, with the exception of C. thous. These results reflect the ecological characteristics of the species with the highest roadkill rates. The findings of the present study raise concerns with regard to the impact of highways on the populations of C. thous, as well as the region’s most threatened species. They also indicate the potential functionality of the local protected area, as well as identifying roadkill hotspots, which will support the development of effective mitigation measures.

Ethnomedicinal practices in the arid zone of India: A study in urban and semi-urban areas of Bhuj, Gujarat

Plants are a vital and life-sustaining natural resource as they provide many ecosystem services and supply food, fibre, fuel, medicine, etc. They are distributed heterogeneously in different ecosystems. With the increasing urbanization in all parts of the world, the vegetation overlapped with urban localities like parks, gardens, roadsides, wasteland and other human habitations. Among this vegetation, many of them are used in ethnomedicine or in ayurvedic medicine by people for a long period of time. These valuable plant resources are now under threat due to various anthropogenic activities in the urban landscape. Bhuj is a small historic city in the arid zone of India with a rich diversity of medicinal plants. With the increasing human population and associated developmental activities within the city, many of these plants are under threat of extinction. Therefore, an attempt was made to document these medicinal plants distributed in different parts of the city and their uses for ethnomedicinal purposes. The plants were intensively surveyed and documented using a questionnaire survey, discussion and cross-checked with available literature. A total of 123 species of ethnomedicinal plants were documented and analysed for their uses in curing different health problems and conservation purposes in the urban landscape.

Reduction of Chlamydia pecorum and Koala Retrovirus subtype B expression in wild koalas vaccinated with novel peptide and peptide/recombinant protein formulations

Koalas are an endangered species under threat of extinction from several factors, including infections agents. Chlamydia pecorum infection results in morbidity and mortality from ocular and urogenital diseases while Koala Retrovirus (KoRV) infection has been linked to increased rates of cancer and chlamydiosis. Both C. pecorum and KoRV are endemic in many wild Australian koala populations, with limited treatment options available. Fortunately, vaccines for these pathogens are under development and have generated effective immune responses in multiple trials. The current study aimed to improve vaccine formulations by testing a novel peptide version of the Chlamydia vaccine and a combination Chlamydia – KoRV vaccine. Utilising a monitored wild population in Southeast Queensland, this trial followed koalas given either a ‘Chlamydia only’ vaccine (utilising four peptides from the chlamydial Major Outer Membrane Protein, MOMP), a combination ‘Chlamydia and KoRV’ vaccine (comprised of the chlamydial peptides plus a KoRV recombinant envelope protein (rEnv)) or no treatment. Clinical observations, C. pecorum and KoRV gene expression, serum IgG, and mucosal immune gene expression were assessed over a 17-month period. Overall, both vaccine formulations resulted in a decrease in chlamydiosis mortality, with decreases in C. pecorum, CD4, CD8β and IL-17A gene expression observed. In addition, the combination vaccine group also showed an increase in anti-KoRV IgG production that corresponded to a decrease in detected KoRV-B expression. While these results are favourable, the chlamydial peptide vaccine did not appear to outperform the established recombinant chlamydial vaccine and suggests that a combination vaccine formulated with recombinant MOMP plus KoRV rEnv could capitalize on the demonstrated benefits of both for the betterment of koalas into the future.

Storying species extinction in Avengers: Infinity War and Avengers: Endgame

This article places two Marvel Cinematic Universe (MCU) films, Avengers: Infinity War () and Avengers: Endgame (), in dialogue with the Marvel comic books on which they are based. As this article demonstrates, in their depiction of Thanos and the partial species extinction event, the films deviate substantially from their source material to reflect a contemporary cultural interest and growing anxiety over the real-world threat of species extinction. However, as this article argues, Avengers: Infinity War’s and Avengers: Endgame’s ecocritical potential are limited, owing partly to the villain’s role in superhero films and comic books more broadly. Limits also owe to the anthropocentric viewpoint that underwrites much of superhero fiction. Superheroes may serve a conservative function as an upholder of the social order, but, as this article shows, in Avengers: Infinity War and Avengers: Endgame, as well as films and television series in the MCU set thereafter, this function often comes at the detriment of the conservation of nature and species-other-than-human.

Crepidium ridleyi (J.J.Sm.) Szlach., a threatened endemic terrestrial orchid of Java: A Maxent modeling to predict the current and future potential distribution

Crepidium ridleyi (J.J.Sm.) Szlach. is one of the endemic terrestrial orchids from Java. Due to rapid development and habitat fragmentation, it faces a severe threat of extinction. In this study, we predict the specific habitat of C. ridleyi within Java Island using the future greenhouse gas emission scenarios of RCP 4.5 and RCP 8.5 for the years 2050 and 2070. The occurrences were found in protected sites but have yet to be conserved in ex-situ sites. The current and future of this species distribution model comparison showed that habitat suitability is declining, even projecting the extinction in the worst scenario in the far future. Thus, supporting active conservation efforts for this species is strongly advised to protect it from extinction and use it sustainably.

Is hybridisation with non‐native congeneric species a threat to the UK native bluebell Hyacinthoides non‐scripta?

Societal Impact StatementHybridisation is an important evolutionary force in plants, but it can potentially lead to genetic swamping and extinction of one or both parental species. The threat of extinction is of particular concern if hybridisation occurs between native and introduced species, especially when the native is of national importance. The widespread occurrence of non‐native bluebells in the United Kingdom has raised concerns that the iconic native bluebell could be at risk due to extinction by hybridisation from introduced non‐native bluebells. This study determines the taxonomic identity of non‐natives and investigates the amount of hybridisation occurring in natural and semi‐natural UK bluebell populations.Summary The widespread occurrence of a non‐native bluebell taxon in the UK has raised concerns that the iconic native bluebell H. non‐scripta (Asparagaceae) could be at risk due to extinction by hybridisation from introduced non‐native congeners. Understanding the nature of this threat requires quantification of the extent of hybridisation between the native and non‐native taxa. An additional complication is taxonomic uncertainty regarding the identity of the non‐native bluebells in the United Kingdom that are colloquially referred to as the ‘Spanish’ bluebell (H. hispanica). We collected 501 bluebell samples from 56 populations in the United Kingdom (H. non‐scripta and non‐natives) and the Iberian Peninsula (H. hispanica). The samples were assayed for variation at 1871 nuclear and 17 plastid single nucleotide polymorphisms. Our genetic analyses demonstrated that non‐native bluebells in the United Kingdom are not H. hispanica but the hybrid between H. hispanica and H. non‐scripta. Moreover, they supported the hypothesis that Portugal is the country of origin of the first H. hispanica introductions to the United Kingdom. The frequency of hybrids was about 16%. Backcrosses between the (hybrid) non‐native bluebell and the native H. non‐scripta were primarily found in public parks. Of the sampled individuals for H. non‐scripta from natural habitats, only 2% showed evidence of introgression. Although hybridisation might be frequent in locations where non‐native bluebells have been introduced, we found no evidence of large‐scale introgression in natural H. non‐scripta populations. Therefore, our results do not support concerns of an ‘extinction by hybridisation’ scenario.

Lanting House Preservation Based on River Culture In Sasirangan Village, Banjarmasin

The shift in time has brought about changes that clearly leave the cultural identity of the archipelago. Sasirangan Village is one of the villages located in the middle of Banjarmasin City. This village still has a strong atmosphere, especially in the diversity of architecture in the area. River culture is still visible in this village, both for daily needs and also land for housing, namely Rumah Lanting. There are 3 Lanting houses in Sasirangan Village. The lack of a number of Lanting Houses left at this time raises a concern that there is a threat of extinction from cultural heritage. In this case, it is necessary to have a study of the architectural concept of the Lanting House to determine the right steps in preserving the Lanting House. The results of this study found that the right effort to preserve the Lanting House in Sasirangan Village was a revitalization effort that did not require material replacement and developed it as a Sasirangan gallery or souvenir shop that supports local wisdom and the identity of Sasirangan Village.

지속가능성 확보를 위한 제주 마을의 ‘관계인구’ 형성 사례 연구

Recently, the concept of “relational population” has been mentioned as an alternative to overcome the crisis of local extinction. This study introduces the concept of “relational population” which was first discussed in Japan. Then, applying the concept of relational population to the local situation of Jeju where the outflow of young population and the re-outflow of immigrants are problematic, the current resident population is assumed to be “potential relational population”. In the case study area of Gwideok 1-ri, the elementary school in the area became a candidate for elementary school consolidation due to a sharp decline in population. Residents felt the threat of village extinction and considered ways to secure the sustainability of the region, such as inducing households with school-age children, organizing a village education community, and holding small-scale festivals led by residents. This study is an attempt to interpret community activities in the region as “experiences of forming relationships” at a time when the concept of “relational population” is being actively discussed in Korea.
