Conception Island is a remote island bank in the central Bahamas, the entirety of which is encompassed within the Conception Island National Park. Conception Island is of vital importance to numerous threatened and critically endangered wildlife species, but tracking visitation is considered challenging as there is no warden and not all vessels follow registration rules. To augment understanding of park visitation, we obtained daily satellite imagery from Dove CubeSat® satellites managed by the company Planet® to characterise diurnal marine vessel traffic around Conception Island between 2016 and 2021. We obtained a total of 888 observable days, which yielded 1,197 vessel detections. Using these remote observations, we were able to geolocate vessels that visited Conception Island National Park over this period, as well as estimate the length overall of each vessel to within 10 m. We found that peak visitation to the National Park occurs in the spring, a time that corresponds to when migrating songbirds arrive at the island, when the critically endangered Silver Boa is mating, when White-tailed Tropicbirds are using the island for mating, and when Green Turtles are starting to lay eggs. This study provides the first analysis of marine vessel visitation to Conception Island National Park and we believe that these data show that the park is visited far more frequently than was appreciated.
受孕岛是巴哈马中部的一个偏远岛礁,整个岛礁都被纳入受孕岛国家公园。概念岛对众多受威胁和极度濒危的野生动物物种至关重要,但由于没有看守人,而且并非所有船只都遵守登记规则,因此跟踪访问情况被认为具有挑战性。为了加深对公园游览情况的了解,我们从 Planet® 公司管理的 Dove CubeSat® 卫星上获取了每日卫星图像,以描述 2016 年至 2021 年期间感孕岛周围昼夜海上船只交通的特点。我们总共获得了 888 个可观测日,探测到 1197 艘船只。我们发现,国家公园的高峰期出现在春季,与迁徙鸣禽抵达该岛、极度濒危的银蟒交配、白尾海鸦交配以及绿海龟开始产卵的时间相吻合。这项研究首次分析了海船到访康菲岛国家公园的情况,我们相信,这些数据表明,到访康菲岛国家公园的频率远远高于人们的想象。

The rugged topography, harsh climate and limited livelihood options have resulted in pastoralism being the predominant land use in the Himalayan landscape. To identify the most significant sites in this landscape, we employed the concept of ‘High Conservation Value Areas’ (HCVAs) in Thanpattan, one of the largest pastureland in Lahaul-Spiti. We have examined this region as a potential HCVA, providing information on biological diversity, pastoralism and related threats. The Gaddi community of Chamba and Bharmour districts relies on these pastures for their livelihoods, and several threatened flora and fauna species also call the area home. We found that Thanpattan fulfils all six criteria for HCVAs and is undoubtedly an HCVA due to its biodiversity values and the dependency of the indigenous communities on the region.
崎岖的地形、恶劣的气候和有限的生计选择导致畜牧业成为喜马拉雅山地貌中最主要的土地利用方式。为了确定这一地貌中最重要的地点,我们在拉霍尔-斯皮提最大的牧场之一坦帕坦采用了 "高保护价值区"(HCVAs)的概念。我们将该地区作为潜在的高保护价值区进行了研究,提供了有关生物多样性、畜牧业和相关威胁的信息。占巴(Chamba)和巴莫尔(Bharmour)地区的嘎迪(Gaddi)社区以这些牧场为生,一些受威胁的动植物物种也以该地区为家。我们发现 Thanpattan 符合高危植物区的所有六项标准,由于其生物多样性价值和土著社区对该地区的依赖性,它无疑是一个高危植物区。

The Protected Area Network (PAN) in Palestine has undergone a comprehensive evaluation and revision to ensure its effectiveness in conserving biodiversity. This re-evaluation was necessary as the previous PAN lacked clear rationale and included areas designated for non-biological reasons. The evaluation process involved analysing the 50 areas in the previous PAN, as well as conducting Marxan analysis and incorporating new data based on IUCN criteria. The evaluation process led to eliminating, combining and adjusting areas, resulting in a revised PAN consisting of 28 areas. This updated PAN represents all vegetation types and phytogeographical zones in Palestine, effectively protecting key ecoregions in the Mediterranean hotspot. The revision of the PAN has increased the total protected land mass from 9 per cent to 9.98 per cent. This expansion provides additional areas where biodiversity can thrive undisturbed, ensuring the long-term survival of species and ecosystems. The updated PAN was adopted at the highest level of government, signifying the importance and commitment to biodiversity conservation in Palestine. This achievement demonstrates the progress made by Palestine in safeguarding its natural heritage.
对巴勒斯坦的保护区网络(PAN)进行了全面评估和修订,以确保其在保护生物多样性方面的有效性。重新评估是必要的,因为之前的 PAN 缺乏明确的理论依据,其中包括出于非生物原因而指定的区域。评估过程包括分析前一个 PAN 中的 50 个区域,进行 Marxan 分析,并根据 IUCN 标准纳入新数据。在评估过程中,对一些区域进行了剔除、合并和调整,最终形成了由 28 个区域组成的修订版 PAN。更新后的 PAN 代表了巴勒斯坦的所有植被类型和植物地理区,有效保护了地中海热点地区的主要生态区。对 PAN 的修订使受保护土地总面积从 9% 增加到 9.98%。这一扩大为生物多样性提供了更多不受干扰的生长区域,确保了物种和生态系统的长期生存。更新后的 PAN 获得了政府最高层的通过,表明了巴勒斯坦对生物多样性保护的重视和承诺。这一成就表明巴勒斯坦在保护其自然遗产方面取得了进展。

Social media as a contributor to conflicts in protected areas: experiences, problems, and potential solutions 社交媒体助长保护区冲突:经验、问题和潜在解决方案
Q1 Environmental Science Pub Date : 2023-11-01 DOI: 10.2305/ulmj5060

Within two decades, social media has profoundly changed modern society. The various effects of this rapid development are increasingly the subject of interdisciplinary research. For protected areas, the focus has so far been on the possibilities of social media as a means of visitor communication and monitoring. This is an exploratory study identifying case studies of protected areas where visitors’ use of social media has contributed to negative environmental effects. Furthermore, potential measures to address these challenges are provided. Data collection was conducted with a selective review of academic and non-academic literature using a global research framework and EU-wide qualitative email interviews with staff from 44 national parks. The research results were structured using the DPSIR framework of the European Environment Agency. Social media trend-driven mass tourism and dissemination of nature-damaging behaviour via social media appear to be the most pressing issues. To implement conservation measures successfully and ensure long-term conservation goals, protected area management must consider the potential negative effects of social media. As digitisation progresses, the urgency of corresponding studies and measures increases. The enhancement of digital skills and digital visitor guidance by nature conservation actors may help to counteract future negative environmental effects.
二十年间,社交媒体深刻地改变了现代社会。这种快速发展的各种影响日益成为跨学科研究的主题。对于保护区而言,迄今为止的研究重点是社交媒体作为游客交流和监控手段的可能性。这是一项探索性研究,旨在确定游客使用社交媒体造成负面环境影响的保护区案例研究。此外,还提供了应对这些挑战的潜在措施。在收集数据的过程中,我们使用全球研究框架对学术和非学术文献进行了有选择性的审查,并对 44 个国家公园的工作人员进行了全欧盟范围的定性电子邮件访谈。研究结果采用了欧洲环境署的 DPSIR 框架。社交媒体趋势驱动的大众旅游和通过社交媒体传播破坏自然的行为似乎是最紧迫的问题。为了成功实施保护措施并确保实现长期保护目标,保护区管理必须考虑社交媒体的潜在负面影响。随着数字化进程的推进,相应研究和措施的紧迫性也随之增加。自然保护行动者加强数字技能和数字游客指导可能有助于抵消未来的负面环境影响。

Increasing demand for Elaeis guineensis (African Oil Palm) products both for domestic and industrial use has led to its continuous expansion. The influence of oil palm plantation establishment on the economic well-being of communities and ecosystems cannot be over-emphasised. The study focuses on the rapid expansion of oil palm plantations within all protected areas and forest reserves in the lowland rainforests of Ondo State, Nigeria using. Object-Based Image Analysis (OBIA) was used to map oil palm expansion using 10-metre resolution Sentinel-2A images for 2015 and 2020 in Google Earth Engine (GEE). We found expansion of both smallholder and commercial oil palm plantations within eight of the thirteen protected areas with three protected areas (Ipele, Onisere and Akure Ofosu) showing a significant increase in oil palm plantation establishment. The use of object-based classification techniques, which combines contextual information within the image domain to discriminate landscape features such as oil palm canopy features, was effective in delineating oil palm from the forest canopy and other crops. While Google Earth Engine, a server-based remote sensing domain with petabytes of data, is effective for monitoring large-scale tropical forests.
国内和工业对非洲油棕(Elaeis guineensis)产品的需求不断增长,导致其规模持续扩大。建立油棕种植园对社区经济和生态系统的影响怎么强调都不为过。本研究重点关注尼日利亚翁多州低地热带雨林所有保护区和森林保护区内油棕种植园的快速扩张。在谷歌地球引擎(GEE)中使用基于对象的图像分析(OBIA),利用分辨率为 10 米的哨兵-2A 图像绘制了 2015 年和 2020 年的油棕扩张图。我们发现,在 13 个保护区中的 8 个保护区内,小农和商业油棕榈种植园都有所扩大,其中 3 个保护区(Ipele、Onisere 和 Akure Ofosu)的油棕榈种植园数量显著增加。基于对象的分类技术结合了图像域中的上下文信息来区分景观特征(如油棕树冠特征),在将油棕从森林树冠和其他作物中划分出来方面非常有效。谷歌地球引擎是一个基于服务器的遥感域,拥有 PB 级数据,可有效监测大规模热带森林。

Growing attention is being given to protected areas and the ability of their natural capital assets to provide a varied and long-term stream of benefits to individuals and society in general. These areas are often heralded for ensuring natural capital assets persist, but value is often limited to the economic impact of visitor expenditures and the associated effects on regional and national economies. Few studies have attempted to quantify the economic value of natural capital assets in protected areas, especially in Canada. This study uses a benefit transfer approach to produce an initial estimate of the potential economic value of ecosystem services and natural capital associated with the terrestrial and marine environments in Canada’s federal system of national parks and national marine conservation areas. The results suggest that the economic value of these assets ranges between CA$ 156 billion and CA$ 588 billion annually.
人们越来越关注保护区及其自然资本资产为个人和社会提供各种长期利益的能力。这些地区往往因确保自然资本资产的持续存在而备受赞誉,但其价值往往仅限于游客支出的经济影响以及对地区和国家经济的相关影响。很少有研究尝试量化保护区自然资本资产的经济价值,尤其是在加拿大。本研究采用效益转移方法,对加拿大国家公园和国家海洋保护区联邦系统中与陆地和海洋环境相关的生态系统服务和自然资本的潜在经济价值进行了初步估算。结果表明,这些资产每年的经济价值在 1,560 亿加元到 5,880 亿加元之间。

The increasing human population which promotes the conversion of secondary forests into other land use types has resulted in the decrease of forest areas in Nigeria. This study examined the causes of secondary forest loss in Osho Forest Reserve, Nigeria. Changes in Land Use Land Cover (LULC) were assessed using Landsat 5 TM and Landsat 8 OLI/TC images for four timelines over a period of 38 years (1984, 2013, 2017 and 2022). Results showed an increase in area of plantations, bare land and farmland, leading to a decrease in secondary forest cover. Farmland increased from 731 ha to 859 ha at the rate of 3.7 ha yr-1, bare land increased from 314 ha to 523 ha at 5.5 ha yr-1, plantations increased from 1,105 ha to 1,495 ha at 10.3 ha yr-1,while secondary forest drastically reduced from 1,132 ha to 405 ha at 19.1 ha yr-1. At this rate, secondary forest is estimated to be lost in the study area by 2050.. Osho Forest Reserve requires immediate management interventions driven by updated laws and policies, silvicultural treatment, community engagement and ecosystem rehabilitation. In addition, implementation of sustainable forest management would enhance secondary forest recovery.
人口的增加促进了次生林向其他土地利用类型的转化,导致尼日利亚森林面积的减少。本研究探讨了尼日利亚奥肖森林保护区次生林减少的原因。使用 Landsat 5 TM 和 Landsat 8 OLI/TC 图像评估了 38 年间(1984 年、2013 年、2017 年和 2022 年)四个时间段内土地利用土地覆盖(LULC)的变化。结果显示,种植园、裸地和农田面积增加,导致次生林覆盖面积减少。农田以每年 3.7 公顷的速度从 731 公顷增加到 859 公顷,裸地以每年 5.5 公顷的速度从 314 公顷增加到 523 公顷,人工林以每年 10.3 公顷的速度从 1105 公顷增加到 1495 公顷,而次生林以每年 19.1 公顷的速度从 1132 公顷锐减到 405 公顷。按照这个速度,预计到 2050 年,研究区内的次生林将消失殆尽。奥修森林保护区需要立即采取管理措施,包括更新法律和政策、造林处理、社区参与和生态系统恢复。此外,实施可持续森林管理将促进次生林的恢复。

This paper introduces the inaugural rapid evaluation of river dolphin habitats, coinciding with managed sites in Asia and South America. Covering all six river dolphin species (including the sole freshwater porpoise worldwide), each is classified as Endangered or Critically Endangered on the IUCN Red List. The Conservation Assured | River Dolphin Standards (CA|RDS) offer tailored guidelines for the proficient oversight of protected areas for river dolphins. The abbreviated CA|RDS version, termed CA|RDS Lite, involves a questionnaire-based survey conducted by managers and stakeholders at 40 sites across 10 of the 14 countries within the river dolphin range. Both continents face river dolphin endangerment from fishing and climate change. In Asia, risks are more diverse, with smaller populations compared to South America. Insufficient funding and management capacity emerge as significant hurdles. Inadequate collaboration with areas outside the protected area boundary impedes effective river dolphin population management. Encouragingly, the survey highlights active involvement of local communities and stakeholders in site management. CA|RDS Lite offers a quick overview of site management efficacy, pinpointing crucial management requirements and urgent river dolphin sites necessitating intervention. It also sets the stage for the complete application of CA|RDS standards and their use as an accreditation and management instrument.
本文介绍了首次河豚栖息地快速评估,与亚洲和南美洲的管理地点相吻合。在世界自然保护联盟(IUCN)的红色名录中,河豚被列为濒危或极危物种,涵盖了全部六种河豚(包括全球唯一的淡水江豚)。保护有保证的河豚标准》(CA|RDS)为河豚保护区的有效监管提供了量身定制的指导方针。CA|RDS 简化版(CA|RDS Lite)涉及管理者和利益相关者在河豚分布的 14 个国家中的 10 个国家的 40 个地点进行的问卷调查。两大洲都面临着渔业和气候变化对河豚造成的威胁。与南美洲相比,亚洲的风险更为多样,种群数量更少。资金和管理能力不足是主要障碍。与保护区边界以外地区的合作不足阻碍了对河豚种群的有效管理。令人鼓舞的是,调查强调了当地社区和利益相关者积极参与遗址管理。CA|RDS简易版可快速了解现场管理的有效性,指出关键的管理要求和急需干预的河豚地点。它还为 CA|RDS 标准的全面应用及其作为认证和管理工具的使用奠定了基础。

The Conservation Assured | River Dolphin Standards (CA|RDS) offer tailored guidelines for the proficient oversight of protected areas for river dolphins. The abbreviated CA|RDS version, termed CA|RDS Lite, involves a questionnaire-based survey conducted by managers and stakeholders at 40 sites across 10 of the 14 countries within the river dolphin range. Both continents face river dolphin endangerment from fishing and climate change. In Asia, risks are more diverse, with smaller populations compared to South America. Insufficient funding and management capacity emerge as significant hurdles. Inadequate collaboration with areas outside the protected area boundary impedes effective river dolphin population management.

Communities in high-altitude regions are particularly dependent on ecosystem services for their survival. Understanding the economic value of ecosystem services is crucial for sustainable management of mountain ecosystems and associated policy development. This study estimated the economic value of selected ecosystem services provided by the Qurumber National Park (QNP) using data collected from 393 local households. This value was estimated as PKR 738.37 million (US$ 4.28 million 1 ) per year, corresponding to PKR 615,308 (US$ 3569 1 ) per household per year. Provisioning services contributed PKR 706.828 million (US$ 4.01 million 1 ) per year which constituted 96 per cent of the ecosystem service value. This study argues that given the lack of economic opportunities and high poverty rate in the valley communities, pressure on the park’s resources is increasing, resulting in depletion of important ecosystem services in the park, thereby posing a key challenge for conservation efforts. This study recommends a need to better recognise the ecosystem services provided by the park in policy decisions. An efficient institutional mechanism should be developed to provide alternative livelihood options for the local community to minimise pressure on the park’s natural resources. The findings of this study serve as baseline information for both researchers and policymakers to maintain this vitally important mountain national park.
高海拔地区的社区尤其依赖生态系统服务来生存。了解生态系统服务的经济价值对于山地生态系统的可持续管理和相关政策的制定至关重要。本研究利用从393个当地家庭收集的数据,估计了qurber国家公园(QNP)提供的选定生态系统服务的经济价值。这一价值估计为每年7.3837亿卢比(428万美元),相当于每户每年615,308卢比(3569美元)。供应服务每年贡献7.0682.8亿巴基斯坦卢比(401万美元),占生态系统服务价值的96%。本研究认为,由于山谷社区缺乏经济机会和高贫困率,对公园资源的压力正在增加,导致公园重要生态系统服务的枯竭,从而对保护工作提出了关键挑战。这项研究建议在政策决策中需要更好地认识到公园提供的生态系统服务。应建立有效的制度机制,为当地社区提供其他生计选择,以尽量减少对公园自然资源的压力。这项研究的结果可以作为研究人员和政策制定者维护这个至关重要的山地国家公园的基础信息。

This paper provides an update on the 2017 status of Arctic protected areas. It provides an overview of the status and trends of the extent of protected areas in the Arctic and an overview of area-based conservation measures including World Heritage Sites and wetlands. This paper uses the International Union for Conservation of Nature (IUCN) definition for protected areas which includes a wide range of Management Categories – from strict nature reserve to protection with sustainable use. Consequently, the level of protection and governance of these areas varies throughout the circumpolar region. As of 2021, 20.77 per cent of the Arctic’s terrestrial area and 5.24 per cent of its marine areas are protected. Protected area coverage of the Arctic’s terrestrial ecosystems exceeded Aichi Biodiversity Target 11 which aimed for at least 17 per cent of terrestrial and inland water to be protected by 2020. The protected area coverage of marine areas fell short of the Aichi Target for 10 per cent of coastal and marine areas to be protected.
本文介绍了2017年北极保护区的最新情况。它概述了北极保护区的现状和趋势,并概述了基于区域的保护措施,包括世界遗产地和湿地。本文使用了国际自然保护联盟(IUCN)对保护区的定义,其中包括广泛的管理类别——从严格的自然保护区到可持续利用的保护区。因此,这些地区的保护和治理水平在整个环极地地区各不相同。截至2021年,北极20.77%的陆地面积和5.24%的海洋面积受到保护。北极陆地生态系统的保护区覆盖率超过了爱知生物多样性目标11,该目标旨在到2020年保护至少17%的陆地和内陆水域。海洋区域的保护区覆盖率达不到爱知县10%的沿海和海洋区域的目标。
