The major European population of the lesser kestrel Falco naumanni, a migratory falcon listed in Annex I of the Birds Directive, occurs in low-input farming systems in the Mediterranean basin, including Greece. The aim of this study was to identify foraging habitats of lesser kestrels and relate them to the delimited SPAs in the agro-ecosystems of Greece, where the stronghold of the species population for Greece occurs. Foraging habitat preferences were assessed using Poisson regression models （PRMs）. SPAs were examined on whether they can effectively protect foraging habitats for breeding lesser kestrels in the study area. Foraging lesser kestrel abundance was positively associated with grasslands and non-irrigated land （dry cereals）, and negatively associated with irrigated land （wet cotton）, scrubland and woodland. Electricity facilities were used as foraging perches by lesser kestrels. The current SPAs cover a small percentage of the species＇ foraging sites and cannot be considered coherent enough to support and protect the foraging habitats of lesser kestrels and other priority species in the agro-ecosystems of the study area. Proposals for effective conservation of low-input farming systems, supporting priority species, are also presented.展开更多

Thisstudy aims to evaluate the ecological, social, economic, institutional, and infrastructural sustainability of the Maros–Watampone road corridor that crosses TN Babul. Using a qualitative descriptive design, the research employed theMultidimensional Scaling (MDS) method supported by leverage and Monte Carlo analysis. Data were gathered fromkey stakeholders through purposive sampling and analyzed based on sustainability attributes across five dimensions.The findings reveal that environmental, institutional, and infrastructure dimensions scored in the "less sustainable"category, indicating high ecological risk and governance gaps. In contrast, economic and social dimensions weremoderately sustainable, reflecting emerging opportunities for inclusive growth. Sensitive attributes influencingsustainability include habitat fragmentation, road design, governance coordination, and community participation. Thestudy concludes that balancing development with conservation requires integrated, multi-stakeholder strategies andtargeted interventions that address the most vulnerable sustainability dimensions.展开更多

The conservation objectives of protected areas have shifted from a narrow emphasis on biodiversity to encompass broader considerations such as ecosystem stability, community resilience to climate change, and enhancement of human well-being. Given these multifaceted objectives, it is imperative to judiciously allocate resources to effectively conserve biodiversity by identifying strategically significant areas for conservation, particularly for mountainous areas. In this study, we evaluated the representativeness of the protected area network in the Qin ling Mountains concerning species diversity, ecosystem services, climate stability and ecological stability. The results indicate that some of the ecological indicators are spatially correlated with topographic gradient effects. The conservation priority areas predominantly lie in the northern foothills, the southeastern, and southwestern parts of the Qinling Mountain with areas concentrated at altitudes between 1,500-2,000 m and slopes between 40°-50° as hotspots. The conservation priority areas identified through the framework of inclusive conservation optimization account for 22.9 % of the Qinling Mountain. Existing protected areas comprise only 6.1 % of the Qinling Mountain and 13.18 % of the conservation priority areas. This will play an important role in achiev ing sustainable development in the region and in meeting the post-2020 biodiversity target. The framework can advance the different objectives of achieving a quadruple win and can also be extended to other regions.展开更多

The methods of priority planning include hot-spots analysis, gap analysis, systematic conservation planning analysis and multi-criteria decision analysis. The key issues of priority area planning include the determination of the protect objects, the analyses of the protec- tion value and protection cost, the win-win development of protection and economy, and the changes of the management strategies of the protected areas. In this study, the features and research progress of different conservation methods were analyzed, and based on the discussion on the key issues of the planning of the protected areas, the application prospect of different methods was analyzed.展开更多

While Bangladesh has gained a degree of prominence in the world for its successful social forestry programs, the concept of collaborative pro- tected area management is rather new in the country, initiated in 2004 by the Bangladesh Forest Department in five PAs with financial assistance from USAID. Based on empirical evidence from three of the pilot PAs, we examined the achievements and associated challenges and prospects for co-management. Our fieldwork revealed a number of challenges faced by co-management institutions： （1） institutions were dominated by the elite group, overshadowing the voice of the community people; （2） mutual trust and collective performance are key to good governance but had not taken root in the PAs; （3） encroachment onto forest land and subsequent conversion to agriculture remained a serious problem that discouraged forest-dependent people from participating actively in co-management initiatives; （4） legal provisions （including acts, rules and policies） were not clearly and adequately disseminated and understood at the community level; （5） there remained a degree of ambiguity regarding the roles and responsibilities of forest department （FD） and co-management committees （CMC） in field operations, and this was not enhancing transparency and accountability of the overall initiative; （6） the long-term sustainability of co-management institutions was another major concern, as the local intuitional structure was still in a nascent stage, and provisioning of resources （either internally or externally） remained somewhat uncertain. We offer recommendations for improve- ment.展开更多

The study was designed to identify recreational potential of the Carpathian national parks （Bieszczady National Park, Bahia G6ra National Park, Goree National Park and Magura National Park; southern Poland） and to compare these findings with the actual number of visitors. The information received on the recreational potential of parks is important from the point of view of protection of natural resources and the financial situation of the parks. The calculated ratio may be an effective tool of management for park administration, that allows to reconcile statutory social and protective functions of national parks. The study determined the recreational potential of the forests with the use of recreational valorisation method designed for areas with varied terrain, and the evaluated factors included the stands of trees with their habitat and land relief. The permissible number of national park visitors, expressed as man- hour/ha/year ranges from 19.31 in Bieszczady National Park （BG： 19~ 35＇ E, 49~ 35＇ N） to 32.06 in in Bieszczady National Park （B： 22~ 40＇ E, 49~ lo＇ N）. In 3 out of 4 investigated parks, Magura National Park （M： 21025＇ E, 49~ 30＇ N）, Gorce National Park （G： 20~ lo＇ E, 49~ 35＇ N）, B） recreation carrying capacity was not exceeded, whether or not the strictly protected area is taken into account. Only in BG was the recreation carrying capacity exceeded by nearly 24%, or by 85% if the strictly protected area isexcluded from tourism-related exploitation. The presented procedure for monitoring access to mountain forests in national parks, from the viewpoint of natural resources conservation, can be applied in other mountainous areas covered with forests and exposed to tourist and recreational traffic, and in forests facing particular risk of recreational damage, e.g. in urban and suburban forests growing in areas with varied orography.展开更多

文摘In Southwest China,five Nature Reserves(NRs)(Mangkang,Baimaxueshan,Yunling,Habaxueshan,and Yunlongtianchi)play a key role in protecting the endemic and endangered Yunnan snub-nosed monkey(YSM)(Rhinopithecus bieti).However,increasing human activities threaten its habitats and corridors.We used a GIS-based Niche Model to delineate potential core habitats(PCHs)of the YSMs and a Linkage Mapper corridor simulation tool to restore potential connectivity corridors(PCCs),and defined five scenarios.A normalized importance value index(NIVI)was established to identify the protection priority areas(PPAs)for the YSMs for five scenarios.The results indicated that locations of the habitats and corridors were different in the five scenarios,thereby influencing the distribution of the PPAs and protection network of the YSMs.The NIVI value of Baimaxueshan nature reserve was 1 in the five scenarios,which implied the maximum importance.There were only 7 PCHs and 16 PCCs(with the longest average length of 223.13 km)which were mainly located around 5 NRs in scenario III.The protection network of the YSMs was composed of 16 PCHs,18 PCCs,and 5 NRs.Under each scenario,most of the PCHs and the PCCs were located in the south of the study area.The five NRs only covered 2 PPAs of the YSMs.We suggest that the southern part of the study area needs to be strictly protected and human activities should be limited.The area of the five NRs should be expanded to maximize protection of the YSMs in the future.

文摘In order to meet the requirements of information exchange varieties and manners in wide area protection system, a communication service model based on IEC 61850 is proposed. This service model can realize communication consistency and cooperation between different types of devices. Furthermore, the communication reliability and time delay performance are guaranteed to meet the requirements of relay protection from the upper layer. Message structure of generic sub-station event (GSE) and its communication mechanism are discussed. General methods to communicate digital information by generic substation status event (GSSE) and communicate analog sampling information by sampling analog value (SAV) of GSE are proposed.
文摘Global marine ecosystems are signiicantly endangered by microplastic pollution,leading to comprehensive investigations into its distribution and impacts on the health of ecosystem.This research employs the Alseamar Autonomous Underwater Vehicle(AUV)known as Glider to investigate microplastic concentrations within the Al Hoceima Marine Protected Area(MPA).Our objective is to identify spatial patterns that reveal pollution hotspots and furnish data for targeted conservation efforts and pollution prevention.We aim to identify regions with elevated microplastic concentrations by meticulously analyzing microplastic level graphs,with a speciic focus on temporal variations.The results reveal notable patterns,such as increased densities aroundishing harbors and near urban centers,potentially linked to anthropogenic activities.Additionally,we observe variations in pollution levels throughout different glider operation cycles,underscoring the importance of understanding the spatio‑temporal dynamics of microplastic distribution.Al Hoceima Marine protected areas exhibiting lower microplastic concentrations illustrate the eficacy of such zones in alleviating pollution impacts,thereby underscoring the signiicance of conservation efforts in safeguarding marine biodiversity and ecosystem resilience.Ultimately,our research enhances our comprehension of the pressures exerted by humans on marine environments and underscores the necessity of proactive conservation measures to shield marine ecosystems from the threats posed by microplastic pollution.
文摘Infrastructure development within protected areas has become a critical concern in biodiversity conservation,particularly in ecologically sensitive regions like Bantimurung Bulusaraung National Park (TN Babul), Indonesia. Thisstudy aims to evaluate the ecological, social, economic, institutional, and infrastructural sustainability of the Maros–Watampone road corridor that crosses TN Babul. Using a qualitative descriptive design, the research employed theMultidimensional Scaling (MDS) method supported by leverage and Monte Carlo analysis. Data were gathered fromkey stakeholders through purposive sampling and analyzed based on sustainability attributes across five dimensions.The findings reveal that environmental, institutional, and infrastructure dimensions scored in the "less sustainable"category, indicating high ecological risk and governance gaps. In contrast, economic and social dimensions weremoderately sustainable, reflecting emerging opportunities for inclusive growth. Sensitive attributes influencingsustainability include habitat fragmentation, road design, governance coordination, and community participation. Thestudy concludes that balancing development with conservation requires integrated, multi-stakeholder strategies andtargeted interventions that address the most vulnerable sustainability dimensions.

文摘Climate change is increasingly affecting all aspects of protected areas management from changes of species ranges to visitor experiences.Due to these impacts,there is a need for managers to take more robust approaches to con-sidering the implications of climate change on the overall application and efficacy of protected areas management direction,including the achievement of the goals and objectives contained within management plans.Through a systematic and comprehensive content analysis approach,this study assesses the current extent to which climate change is considered in Canadian protected area management plans.Specifically,we evaluated 63 terrestrial protected area management plans against a set of climate robustness principles.Our content analysis revealed that climate change is currently not effectively factored into Canadian protected area management plans with an average climate robustness score of 18%.Climate robustness score was not found to be correlated with protected area size,International Union for the Conservation of Nature(IUCN)management classification,or jurisdictional authority.Certain climate robustness principles received higher scores across the management plans than oth-ers.For example,the principles of‘diverse knowledge sources’and‘addresses climate change’scored relatively highly whereas‘climate change vulnerability’and‘ecosystem integrity’received the lowest scores.The lack of integration of ecological integrity considerations in management plans was a particularly noteworthy deficiency considering that this guiding principle is the primary legislative objective of many national and sub-national protected areas in Canada.From this assessment,climate change needs to be more effectively and consistently integrated into protected area management plan development and coordinated across associated planning pro-cesses.We discuss the ways in which this can be achieved,for example,by integrating scenario planning into organizational management plan development processes.

文摘Deforestation remains one of the most imminent threats to biodiversity in the tropics.As such,its causes and dynamics need to be studied and understood to put a halt to further forest loss and degradation.In tropical countries such as Uganda,agricultural expansion and wood fuel demand are its leading drivers.While the establishment of protected areas is a key tool in conserving remaining forest biodiversity,results indicate that current management does not sufficiently provide alternatives to forest resources utilised by households and income provided from timber and non-timber forest products.Beyond safeguarding ecosystems,protected areas need to ensure the sustainable socioeconomic development of adjacent communities for effective biodiversity conservation–however,both management and research often neglect to consider all dimensions.In this study,we analysed five decades of forest cover change in the Mount Elgon region,Uganda,by conducting a remote sensing analysis of its protected areas using Landsat MSS and TM data from 1973-2023 in combination with literature and subsequent interview analysis to consider both the ecological and socioeconomic dimension.We applied a random forest approach to differentiate forest and non-forest areas and carried out a pixel-based change detection analysis to differentiate temporal and spatial changes.Throughout the study period of 50 years,forest cover has evolved dynamically within the boundaries of the protected areas of Mount Elgon.A significant decline was observed in both Mount Elgon National Park with a loss of-5.98%(-46.83km²)and Mount Elgon Biosphere Reserve with a loss of-14.96%(-134.33km²).Our results showcase a cycle of deforestation and afforestation that could be tied to a series of development initiatives,re-demarcation of boundaries,changes in management and recurring evictions.Overall,the results lead to the conclusion that the lack of sustainable and efficient management and funding has fostered the rate of deforestation and accelerated ecological degradation in the region,but that existing problems are also rooted in the land tenure history of the region.We recommend the proper implementation of participatory and long-term management approaches on the ground and to address the land rights issue to contribute to both socioeconomic wellbeing and sustainable conservation outcomes.

文摘The Qinghai-Xizang Plateau serves as an extensive gene pool for plateau species and a crucial focal point for global biodiversity conservation.Being a climate-sensitive region,the impacts of climate change have led to habitat loss,population extinction,and ecological imbalances,posing formidable challenges to the sustained ef-fectiveness of existing protected areas.Despite substantial advancements in understanding species distribution,assessing habitat changes,and evaluating the efficiency of protected areas in recent decades,comprehensive evaluations encompassing all protected species are lacking,impeding conservation strategies.In this study,we gathered 137,856 observations,encompassing 2,605 species,and utilized the MaxEnt model to simulate changes in the current distribution patterns of endangered species and suitable habitats under future scenarios.We further proposed a climate smart approach to optimize the boundaries of protected areas in response to climate change.Key findings indicate that(1)the Qinghai-Xizang Plateau harbors 2,605 endangered species,constituting 34.04%of the total endangered species catalog in China;(2)current high-adaptation habitats of Qinghai-Xizang Plateau cover a mere 7%of the plateau,showing minimal alteration in protected efficiency under climate change sce-narios(0.50%increase);(3)incorporating the effects of climate change in adjusting protected area boundaries enhances their efficiency by an average of 20.52%.Our proposed methodology holds promise for safeguard-ing endangered species on the Qinghai-Xizang Plateau and offers significant implications for analogous regions worldwide.

文摘Establishing and maintaining protected areas is a pivotal strategy for attaining the post-2020 biodiversity target. The conservation objectives of protected areas have shifted from a narrow emphasis on biodiversity to encompass broader considerations such as ecosystem stability, community resilience to climate change, and enhancement of human well-being. Given these multifaceted objectives, it is imperative to judiciously allocate resources to effectively conserve biodiversity by identifying strategically significant areas for conservation, particularly for mountainous areas. In this study, we evaluated the representativeness of the protected area network in the Qin ling Mountains concerning species diversity, ecosystem services, climate stability and ecological stability. The results indicate that some of the ecological indicators are spatially correlated with topographic gradient effects. The conservation priority areas predominantly lie in the northern foothills, the southeastern, and southwestern parts of the Qinling Mountain with areas concentrated at altitudes between 1,500-2,000 m and slopes between 40°-50° as hotspots. The conservation priority areas identified through the framework of inclusive conservation optimization account for 22.9 % of the Qinling Mountain. Existing protected areas comprise only 6.1 % of the Qinling Mountain and 13.18 % of the conservation priority areas. This will play an important role in achiev ing sustainable development in the region and in meeting the post-2020 biodiversity target. The framework can advance the different objectives of achieving a quadruple win and can also be extended to other regions.

文摘Marine protected areas(MPAs)play a critical role in maintaining marine ecosystem health,conserving biodiversity,and sustaining coastal livelihoods and socio-economic benefits.However,MPAs in China still face significant design and management limitations,including a lack of a robust scientific basis for boundary delineation,weak enforcement capacity,poor adaptability to environmental and socio-economic changes,and insufficient integration of the ocean’s three-dimensional characteristics.These limitations are particularly evident in the context of climate change,overexploitation of marine resources,and the complex dynamics of ecosystems.This study systematically reviews the current status and challenges of MPAs in China,with a specific focus on the need for and benefits of dynamic and threedimensional protected areas for marine conservation.Dynamic protected areas,supported by real-time monitoring and flexible boundary adjustments,can more effectively respond to the migratory patterns of marine species and seasonal distribution shifts along China’s coast.On the other hand,three-dimensional protected areas enhance ecosystem protection by incorporating vertical ecological gradients and ocean depth,offering a vital complement to the predominantly two-dimensional protection approach currently in use.The study indicates that,with current technological and data capabilities,effective implementation of these advanced approaches requires precision marine observations,advanced analysis methods,and coordinated efforts among diverse stakeholders.In response,the study synthesizes multiple case studies to illustrate the potential ecological,managerial,and policy-related outcomes of dynamic and three-dimensional MPAs.It proposes strategies for optimization,implementation pathways,and targeted policy recommendations.Ultimately,the study emphasizes the critical role of scientific planning and technological innovation in enhancing the effectiveness of MPAs in China.It calls upon policymakers and the broader society to increase attention and investment in dynamic and three-dimensional marine conservation approaches.This work not only provides a scientific foundation for more precise and efficient marine governance in China,but also lays crucial foundation for achieving ocean-related sustainable development goals aligned with China’s national context.
文摘In this research,we examine how the Al Hoceima Marine Protected Area(MPA),located in the southwest Mediterranean Sea,can be effectively monitored using the SeaExplorer glider—an advanced autonomous underwater vehicle(AUV)designed for long‑duration oceanographic missions.The study focuses on the glider’s ability to simultaneously observe a variety of environmental parameters,including temperature,conductivity,oxygen,and chlorophyll,during its deployment across multiple transects.The primary objective of the mission is to improve understanding of the vertical thermal structure and seasonal dynamics of the water column in this ecologically signiicant region.To achieve this,we apply Gaussian Process(GP)regression techniques to the glider‑derived temperature data.This statistical method enables the smoothing and interpolation of irregularly spaced in situ measurements,thereby improving the visibility and interpretation of stratiication patterns throughout the water column.Although the glider followed a predetermined course,the data‑driven analysis suggests that adaptive sampling strategies—such as adjustments based on real‑time outliers—could be valuable in future missions.Our results,which show distinct thermal layering and seasonal variability,are crucial for informing ecosystem function assessments and climate resilience planning.This study also discusses how integrating machine learning into glider‑based monitoring could enhance MPA observation systems and promote adaptive,evidence‑based management.

文摘The planning of prior conservation areas is an important part of nature re- serve system, ：it is of great significance for biodiversity conservation. The methods of priority planning include hot-spots analysis, gap analysis, systematic conservation planning analysis and multi-criteria decision analysis. The key issues of priority area planning include the determination of the protect objects, the analyses of the protec- tion value and protection cost, the win-win development of protection and economy, and the changes of the management strategies of the protected areas. In this study, the features and research progress of different conservation methods were analyzed, and based on the discussion on the key issues of the planning of the protected areas, the application prospect of different methods was analyzed.
文摘Establishment of Protected Areas （PAs）, in the face of rapid deforestation, forest degradation and climate change has been one of the key efforts in conservation of biodiversity worldwide in recent times. While Bangladesh has gained a degree of prominence in the world for its successful social forestry programs, the concept of collaborative pro- tected area management is rather new in the country, initiated in 2004 by the Bangladesh Forest Department in five PAs with financial assistance from USAID. Based on empirical evidence from three of the pilot PAs, we examined the achievements and associated challenges and prospects for co-management. Our fieldwork revealed a number of challenges faced by co-management institutions： （1） institutions were dominated by the elite group, overshadowing the voice of the community people; （2） mutual trust and collective performance are key to good governance but had not taken root in the PAs; （3） encroachment onto forest land and subsequent conversion to agriculture remained a serious problem that discouraged forest-dependent people from participating actively in co-management initiatives; （4） legal provisions （including acts, rules and policies） were not clearly and adequately disseminated and understood at the community level; （5） there remained a degree of ambiguity regarding the roles and responsibilities of forest department （FD） and co-management committees （CMC） in field operations, and this was not enhancing transparency and accountability of the overall initiative; （6） the long-term sustainability of co-management institutions was another major concern, as the local intuitional structure was still in a nascent stage, and provisioning of resources （either internally or externally） remained somewhat uncertain. We offer recommendations for improve- ment.
文摘The article presents research findings related to recreational use of forests located in protected mountainous areas with forestage of over 80%. The study was designed to identify recreational potential of the Carpathian national parks （Bieszczady National Park, Bahia G6ra National Park, Goree National Park and Magura National Park; southern Poland） and to compare these findings with the actual number of visitors. The information received on the recreational potential of parks is important from the point of view of protection of natural resources and the financial situation of the parks. The calculated ratio may be an effective tool of management for park administration, that allows to reconcile statutory social and protective functions of national parks. The study determined the recreational potential of the forests with the use of recreational valorisation method designed for areas with varied terrain, and the evaluated factors included the stands of trees with their habitat and land relief. The permissible number of national park visitors, expressed as man- hour/ha/year ranges from 19.31 in Bieszczady National Park （BG： 19~ 35＇ E, 49~ 35＇ N） to 32.06 in in Bieszczady National Park （B： 22~ 40＇ E, 49~ lo＇ N）. In 3 out of 4 investigated parks, Magura National Park （M： 21025＇ E, 49~ 30＇ N）, Gorce National Park （G： 20~ lo＇ E, 49~ 35＇ N）, B） recreation carrying capacity was not exceeded, whether or not the strictly protected area is taken into account. Only in BG was the recreation carrying capacity exceeded by nearly 24%, or by 85% if the strictly protected area isexcluded from tourism-related exploitation. The presented procedure for monitoring access to mountain forests in national parks, from the viewpoint of natural resources conservation, can be applied in other mountainous areas covered with forests and exposed to tourist and recreational traffic, and in forests facing particular risk of recreational damage, e.g. in urban and suburban forests growing in areas with varied orography.
