Global ecosystems, particularly in biodiversity-rich tropical rainforests, are increasingly under pressure from human activities. As socio-economic development continues and populations steadily grow, the effective planning of areas surrounding national parks has become a global challenge. This study, based on remote sensing data and utilizing landscape ecology tools, such as ArcGIS 10.8, GeoDa 1.20, and Fragstats 4.2, combines spatial statistical methods, trend analysis, and the Hurst index to conduct a long-term analysis and forecast future trends in vegetation ecological quality indicators (VEQI) and landscape pattern changes within and around the Hainan Tropical Rainforest National Park. VEQI changes across various buffer zones were also assessed. Our results show that both arable and built-up land increased, especially from 2002 to 2022. Arable land decreased from 5566.8 km² to 4796.8 km², then increased to 5904.6 km²; built-up land expanded from 163.97 km² to 314.59 km², reflecting urbanization. Spatiotemporal analysis revealed that 42.54% of the study area experienced significant VEQI changes, with a 24.05% increase (mainly in the northwest) and an 18.49% decrease (mainly in the southeast). The VEQI improvements were consistent across all buffer zones, with the most significant growth in the 7.5 km zone. Landscape indices indicated high fragmentation in coastal areas, while inland areas remained stable, reflecting the tension between conservation and urbanization. These findings provide a theoretical basis for future ecological development and buffer zone policies in the park. Full article

Tourists’ pro-environmental behavior (TPEB) is crucial in promoting the sustainable development of tourism worldwide. It has received increased attention from scholars in different fields of tourism, but relevant research on the normative activation and formation process of TPEB in geotourism is lacking. Given the complexity of behavioral causes and norm activation, this study is grounded in multiple theories, including the norm activation model (NAM), behavioral reasoning theory (BRT), and complexity theory, to illustrate the formation process of TPEB in geotourism. The Zhangye National Geopark, which is located in Gansu Province, China, was chosen as the research case for this study. In total, 502 valid survey responses were utilized for data analysis using partial least squares structural equation modeling (PLS-SEM) and fuzzy set qualitative comparative analysis (fsQCA). The PLS-SEM results showed that tourist intention for pro-environmental behaviors is linearly affected by moral norms, attitude, social norms, and perceived behavioral control, which are the key components in the NAM and BRT. The fsQCA results identified six causal recipes components that influence the formation of intention for pro-environmental behaviors, confirming the causal complexity principle of complexity theory. Among these, environmental awareness, anticipated emotion of pride, moral norms, attitude, and social norms are considered core variables. These research findings provide significant management guidance and strategies for the environmental protection of geoparks and the sustainable development of geotourism. Full article

The Miné-Akiyoshidai Karst Plateau aspiring UNESCO Global Geopark (aUGGp) in western Japan hosts several geologically significant heritage sites, including the Late Paleozoic Akiyoshi Limestone, the Late Triassic Mine Group, the Late Cretaceous Naganobori copper deposits, and the Akiyoshido Cave and karst plateau. The Akiyoshi Limestone at the Kaerimizu site originated as an atoll reef atop a seamount on an oceanic plate. It preserves approximately 80 million years of ancient marine environments and subduction-related tectonic histories. The Mine Group at the Momonoki site, with its coal-bearing strata, contains fossils of the earliest members of Diptera and Hymenoptera. The Naganobori copper mine at the Naganobori site played a vital role in Japanese society from the 8th to the 20th centuries. Meanwhile, the Akiyoshido site, renowned for its scenic beauty, is one of Japan’s most iconic tourist destinations. Using the IUGS guidelines and geoheritage assessment methodology, we reassessed the value and utilization of these geological heritage sites. The Kaerimizu and Momonoki sites were identified as internationally significant and ideal for scientific research. The Naganobori site was determined to be well-suited for educational purposes with national significance, while the Akiyoshido site was deemed optimal for geotourism with national significance.

Climate and geological diversity have been proven to make an important contribution to biodiversity. Volcanic ecosystems often have a long geological history and diverse bedrock, thus shaping a variety of habitats. Understanding the relative importance and role of the contemporary climate and geological bedrock environment in volcanic biodiversity still needs further exploration. To address this knowledge gap, we investigated the patterns of plant diversity and phylogenetic structure at the community level in Qiniangshan Mountain, while also exploring the relationship between biodiversity and regional environmental factors (e.g., climate and bedrock types). In the Qiniangshan Mountain plant communities, species richness is higher at mid-to-high elevations. Montane communities exhibit higher species richness compared to coastal communities. There are significant differences in species richness among plant communities on different bedrock, with the highest species richness found on pyroclastic lava. Bedrock, along with climate factors related to energy and precipitation, collectively influence the patterns of species richness in plant communities. The Net Relatedness Index (NRI) of plant communities is influenced by climate factors and aspects, while the Nearest Taxon Index (NTI) is affected by both bedrock and climate factors. The Phylogenetic Diversity Index (PDI) is primarily related to climate factors. Climate and bedrock collectively influence the patterns of species richness and phylogenetic structure within Qiniangshan Mountain’s plant communities. These findings highlight the profound impact of both climate and bedrock on montane vegetation and community biodiversity. Full article

Arcangelo Scacchi (1810–1893) one of the greatest Italian geoscientists known worldwide, especially for his contributions in the fields of mineralogy and volcanology, dedicated his early years to malacological and zoological works. This paper aims to pay homage to a lesser-known side of the scientist, focusing on a malacological work related to fossils from his hometown, Gravina, in Puglia (southern Italy), located within the boundaries of the MurGEopark, which is aspiring to become a UNESCO Global Geopark (aUGGp), and at the border of Parco Nazionale dell’Alta Murgia (Alta Murgia National Park). Among others, Arcangelo Scacchi described 16 new species of molluscs but his precious collection, hosted in Naples, in the Real Museo Mineralogico (Royal Mineralogical Museum), now Museo di Paleontologia dell’Università di Napoli Federico II (Museum of Palaeontology of the University of Naples Federico II), was partly lost. In recent years, research has allowed the resampling of some species he described for the first time in 1835. Starting from this material, the figure of Scacchi was highlighted to the public through the temporal exhibitions and the use of 3D digital models of these resampled fossils. This activity represents: (i) a tribute to the first modern geoscientist who worked in the area of the MurGEopark, (ii) an instrument to preserve palaeontological remains of international importance, and (iii) a public opportunity to know this kind of geocultural heritage enriching the potential examples of (geo)dissemination in the MurGEopark.

In the inland areas of Campania (Italy), the Taburno-Camposauro Regional Natural Park covers almost 137 square kilometres. It well represents, in the reliefs that give it its name, the southern segment of the Apennine chain. In fact, the rock outcrops, landscape features and surface and ground water make it possible to reconstruct the geological evolution of this area. Nonetheless, it is possible to understand how the history of man, who has frequented these places since ancient times, has developed by taking advantage of the resources offered by this territory. Among these resources, it is believed that the characteristics of the geological heritage spread throughout the Park can also be an opportunity to attract not only researchers, but also significant tourist flows. To this end, not only has the procedure been initiated to be included in the world network of Geoparks, but efforts have also been made to promote the most representative geological sites using the latest communication tools (e.g., social media). Besides these, numerous initiatives aimed at schools and national tourism agencies were developed. Promotion found particular emphasis with the realisation of an art installation by a well-known author in a water catchment system. In fact, this installation triggered an artistic vein around the beauty of the sites, manifested by videos and photo exhibitions and even forms of entertainment. These events have increased interest in the geological heritage, as evidenced by the increase in visitors observed by a specific analysis of the performance of social media posts, as well as frequent visitors to the geoheritage elements of the Park.

The development of geotourism and the establishment of geoparks can generate new job opportunities, new economic activities, and additional sources of income, with great significance in achieving the United Nations Sustainable Development Goals. Tourists often consume more energy and water and generate more waste in order to seek a more comfortable state during their travels. This research took Zhangye Danxia National Geopark in the north slope of the Qinghai–Tibet Plateau in China as an example and combined field research with questionnaires to construct a non-radial model (SBM) based on energy-water-waste-economic nexus. From the perspective of consumption, this research focuses on the consumer characteristics of geotourism sustainability based on the energy–water–waste–economic nexus (GTS-EWWE) and the driving factors behind them under different degrees of consumption. The elderly, children, and high-income tourists can contribute more to the sustainability of geotourism. Stay duration in the geopark and energy consumption are the native driving factors behind the sustainability of geotourism. However, with the improvement of the tourism consumption level, the marginal effect of the negative influence of both factors is diminishing gradually. While tourism expenditure is a positive driving factor, the tourist’s travel mode and the consumer’s awareness of ecological–environmental actions will contribute more to the sustainability of geotourism. New energy technologies to promote the green development of geoparks is significant. This research aims to provide a reference for the sustainability assessment of geoheritage sights and to provide evidence for the appropriate management policy with respect to their sustainable development.

The Northeast China Tiger and Leopard National Park (NCTLNP) is a critical habitat for the endangered Amur tiger and Amur leopard, making it a global biodiversity hotspot. This study explores how changes in landscape patterns have influenced habitat quality in the park, aiming to develop strategies for enhancing biodiversity conservation and ensuring the park’s long-term sustainability. From 2012 to 2017, habitat quality in the NCTLNP experienced a significant decline; however, the launch of the national park pilot program in 2017 resulted in improvements, particularly in core protected areas, where habitat quality increased and landscape fragmentation decreased. These findings indicate that the national park initiative reduced the degradation of habitat quality. Key landscape metrics, especially the Shannon Diversity Index (SHDI), were found to significantly affect habitat quality. Additionally, the interaction between SHDI and landscape contagion (CONTAG) played a pivotal role in shaping habitat quality over time. Areas with high SHDI and low CONTAG showed declines in habitat quality, pointing to the need for focused conservation efforts. This study offers valuable insights for policymakers seeking to improve habitat quality through targeted landscape management practices. Full article

Anthropogenic global challenges and environmental pressures are increasingly significant. Developing pro-environmental behavior and geoethics is crucial for enhancing awareness, action capability, and respect for natural systems. UNESCO Global Geoparks (UGGps) play a vital role in conserving geological and biological diversity while aligning with the United Nations’ Sustainable Development Goals. This quasi-experimental study, conducted during the 4th Summer School of Environmental Education on Geotopes and Sustainability at the Sitia UGGp, uses a pre–post design and comprehensive questionnaire to explore changes in participants’ sense of place and geoethical awareness. Results indicate significant improvements in place attachment, place meaning, and geoethical awareness. These findings suggest that stronger emotional bonds and deeper personal meanings related to the Sitia UGGp correlate with increased geoethical awareness. This research highlights the role of psychological connections in influencing geoenvironmental ethics and underscores the importance of place-based emotional and cognitive bonds in fostering geoethical thinking. However, this study’s limited sample size and the specific geographic context of Sitia UGGp may limit the generalizability of the findings. Despite these limitations, this study provides insights into the interplay of emotions, meanings, and geoethics within the sustainability and resilience spectrum. Full article

Evaluating the conservation effectiveness of multiple types of protected areas (PAs) on carbon sequestration services can enhance the role of PAs in mitigating global warming. Here, we evaluated the conservation status and effectiveness of national parks, nature reserves, forest parks, geo-parks, and scenic spots on carbon sequestration within the Loess Plateau throughout 2000–2020. The results show that all existing PA types have good representation and conservation effectiveness on carbon sequestration. Nature reserves are the most representative of carbon sequestration but are the least effective in protecting carbon sequestration and are the only ones that are weekly effective in protecting critical carbon sequestration. The main factors influencing these results are PA size, 2000 precipitation, slope, change rate of evapotranspiration, PA rank, and 2000 evapotranspiration. We suggest upgrading the critical carbon sequestration distribution areas in scenic spots, forest parks and geo-parks to national parks or nature reserves in the future and implementing appropriate protection and restoration measures in low carbon sequestration areas within grassland and wild plant nature reserves to help achieve the goal of carbon neutrality early.

Fozi Mountain National Geopark is located in Zhenghe County in the northern region of Fujian Province, where the volcanic rocks of the Zhaixia Formation of the Shimaoshan Group are exposed. Zircon U-Pb dating and geochemical analysis were carried out to constrain its age and tectonic environment. The results show that three zircon U-Pb dating samples have attained ages of 99.2 ± 1.0 Ma, 99.6 ± 0.8 Ma, and 99.7 ± 2.0 Ma. Volcanic rocks in the core scenic area of Fozi Mountain were formed during the Late Cretaceous period. Elemental analysis showed that these volcanic rocks were dominated by the shoshonite series. They include gray dacite porphyry, grayish-white breccia tuff, volcanic agglomerate, and gray tuffaceous sandstone. These rocks were characterized by high silicon, high alkali content, and rich potassium levels. Lu-Hf isotope analysis of zircons revealed that their ε_Hf(t) values varied from −8.7 to −6.8. The corresponding T_DM2 values were primarily distributed in the range of 1.71 Ga to 1.59 Ga. These findings indicated that the magma primarily originated from the partial melting of the Mesoproterozoic crystalline basement, accompanied by a small number of mantle-derived materials. Tectonic environment analysis indicated that these rocks were formed in the post-orogenic intraplate extensional environment, which was associated with the back-arc extension or lithospheric thinning caused by the subduction of the paleo-Pacific plate beneath the Eurasian plate. The formation of these volcanic rocks was attributed to post-orogenic magmatism. Full article

Bark beetle outbreaks damage forests and kill trees worldwide, but many aspects of their dynamics remain unexplained. Our aim was to identify predictors for individual tree deaths within the small (0.7 km²) Plešné Lake catchment in the Šumava National Park in southwestern Czechia. Within this area, >60,000 trees were geo-referenced and categorized from ten aerial images (20 cm spatial resolution) between 2000 and 2015. For each year for which aerial images were available, we calculated tree densities of different categories and diameters. Tree height was evaluated by means of LiDAR in two terrestrial campaigns (2010 and 2011). A machine learning technique was then used to evaluate the most important variables. The resulting relationships were largely nonlinear and differed among years; however, individual trait tree height proved to be the most influential variable in each year. Higher trees were more likely to have died during either the undisturbed phase (2000 and 2003), the disturbed phase (2005–2011), or the recovery phase (2013). Our results indicate that salvage logging may not be the most effective measure for protecting trees in small catchments. Full article

A new genus and new species of the euthemistid, Kidaneuthemis ningchengensis gen. et sp. nov., is described from the Middle Jurassic of Inner Mongolia, China. It can be assigned to the Euthemistidae by the several long intercalary veins between RP1 and IR1, IR1 and RP2, as well as between RP2 and IR2 and between IR2 and RP3/4. Kidaneuthemis ningchengensis gen. et sp. nov. distinguishes from the other two genera of this family by the presence of not less than eight intercalary veins between MP and wing margin; about three rows of cells in the distal part between MA and MP; the base of IR2 is two cells distal to that of RP3/4. In addition, a revision of the family Euthemistidae has been proposed. Full article

Seminatural grasslands are among the most threatened habitats in Europe and worldwide, mainly due to changes in/abandonment of their traditional extensive use by grazing animals. This study aimed to develop an innovative model that integrates plant biodiversity, animal husbandry, and geo-informatics to manage and preserve seminatural grasslands in protected areas. With this objective, an integrated study was conducted on the seminatural grasslands in the hilly, montane, and (to a minimum extent) subalpine belts of the Maiella National Park, one of Europe’s most biodiversity-rich protected sites. Plant biodiversity was investigated through 141 phytosociological relevés in homogeneous areas; the pastoral value was calculated, and grasslands’ productivity was measured together with the main nutritional parameters. Uni- and multivariate statistical analyses were performed to identify the main grassland vegetation types, their indicator species and ecological–environmental characteristics, and their pastoral and nutritional values’ variability and differences. A total of 17 grassland types, most of which correspond to habitat types listed in Annex I to the 92/43/EEC Directive, were identified and characterised in terms of their biodiversity and potential animal load. To allow for near-real-time analysis of grasslands, an NDVI-based web interface running on Google Earth Engine was implemented. This integrated approach can provide decision-making support for protected-area managers seeking to develop and implement sustainable grassland management practices that ensure the long-term maintenance of their biodiversity.

Devils Tower is located in Wyoming, USA. It is composed of volcanic elements from the Tertiary Period of geologic time. Geologists are interested in this geosite because it is a unique, upstanding, steep-sided, high-relief exhumed Tertiary-age volcanic plug. As a Native American cultural geosite, however, it is often called Mateo Tepe, and it is a sacred place to over 20 Native American tribes. It was inscribed as America’s first national monument in 1906 by President Theodore Roosevelt, because of its special geology. It is visually dramatic due to its columns, which are understood by earth scientists as a wonder of geology but by Native people as the claw scratches of a spiritual bear. These vertical cracks are the focus of rock climbers and Native people, respectively as opportunities for adventure and self-fulfillment and spiritual paths to another dimension and the achievement of religious balance in the world. Mateo Tepe became a national monument due to it being a unique geologic feature. The geopark concept is used in this analysis to talk about this geologically based monument. Full article
