亚洲象的民族情缘

正最近一段时间以来,西双版纳野生亚洲象的生存环境成为了人们关注的焦点问题:大象的栖息地环境好吗?当地老百姓与大象相处融洽吗?其实,在生态文明的背景下,人与自然和谐共处是乡村振兴工作的应有之义,大型野生兽类自然也就成了主角。在此方面,解读西双版纳地区传统文化与亚洲象保护的关系,可以在现代科学和治理措施之外提供一种新的借鉴。     

太行山华北豹袭击家畜的时空特点与管理建议: 以山西省和顺县为例

人兽冲突是全球野生动物保护面临的共同挑战。袭击家畜是大型食肉动物引发人兽冲突的主要原因之一, 如果管理不当还会导致针对大型食肉动物的报复性猎杀等严重威胁。冲突的缓解需要深入了解冲突发生的规律与原因, 评估当地社区与居民的态度与看法, 以采取因地制宜的管理措施。太行山是华北豹(Panthera pardus japonensis)的核心分布区, 华北豹袭击家牛的问题是该区域野生华北豹保护中面临的一大挑战。本研究以山西省和顺县为研究区域, 在多方联合发起的“和顺县华北豹袭击家牛肇事补偿项目”实施过程中, 系统收集了2015-2019年期间华北豹袭击家畜事件的记录, 结合同期的红外相机监测数据, 探究了袭击事件的时空分布格局, 并从生境和猎物的角度分析了背后的原因。本文还评估了豹肇事造成的经济损失, 以及受损农户对华北豹的态度和对补偿的满意度。2015-2019年, 项目区域内共记录到华北豹袭击家牛事件195起, 向116户受损农户提供补偿资金共27.05万元。分析结果显示, 华北豹袭击家牛事件在夏季最多, 时间上与家牛上山散放的季节重叠; 袭击风险随狍(Capreolus pygargus)相对多度的上升而下降, 随家牛相对多度和距村庄距离的增加而上升, 但保护区内外和华北豹相对多度对袭击风险的影响不显著。对107名受损农户的访谈结果显示, 华北豹袭击家牛事件虽然对当地畜牧业所造成的整体损失较小, 但对受损农户而言其家庭收入损失严重, 因此导致受损农户对华北豹持负面态度, 且认为现有的补偿金额偏低。基于本研究的结果, 我们提出如下管理建议以期缓解未来该地区华北豹带来的人兽冲突: (1)加强放牧管理、改进管理方式, 特别是限制牛群离开村庄的距离, 以及在家牛散放期间将牛群每晚赶回牛圈以降低家畜被袭击的风险; (2)开展禁牧试点, 严格划分允许放牧与禁止放牧的区域; (3)继续开展华北豹袭击家牛的定损与补偿工作, 降低当地农户的经济损失, 同时开展社区走访、自然教育, 提升当地居民对华北豹的容忍度; (4)加强野生动物种群的监测与保护, 促进人与野生动物的和谐共存。     

人与野生动物冲突研究现状及经验启示

人与野生动物冲突是人与自然耦合系统不可避免的负向产物,对冲突的治理是实现保护与发展协调的重要路径。国内外学者对此展开了大量的研究。本文从冲突生成、影响、成本和治理四个方面对现有研究进行梳理,结果表明人与野生动物冲突对保护与发展都造成负面影响,包括社区直接经济损失、人身安全受威胁、福祉降低以及野生动物被伤害、栖息地被挤占。现有研究还存在缺乏跨学科系统研究框架、忽视冲突隐性成本以及对冲突影响研究不深入等不足,未来在科学测度冲突成本、从生态和社会经济视角对冲突影响进行评估以及冲突治理措施多元化方面研究需要深入。在此基础上,从建立中央政府为主、地方政府为辅的野生动物冲突补偿专项基金;政府为主导,企业、社区、国际组织和高校多方利益群体参与机制;人与野生动物冲突分区管理制度;冲突损失核算和申报管理系统;多元化冲突治理模式;冲突减缓土地利用规划体系方面提出现有研究对治理我国人与野生动物冲突的启示。     

卧龙自然保护区与当地社区关系模式探讨

针对目前国内外广泛出现的保护区与当地社区的矛盾冲突,研究以四川卧龙国家级自然保护区(以下简称卧龙保护区)为例,从就业机会、野生动物的破坏及补偿、对资源利用的限制、旅游的开展、社区参与、家畜的饲养和放牧、非木林产品的采集、狩猎、农业活动和传统保护等10个方面,向卧龙保护区内的农户、管理人员、个体经营者和游客等4类人群发放调查问卷,对卧龙保护区与当地社区之间的关系模式(包括发展协调型、社区不利型、保护区不利型和冲突竞争型)及其管理现状和存在的问题进行深入探讨.结果表明,4类人群对卧龙保护区与当地社区关系模式的界定有显著差异(P＜0.05),但皆以发展协调型为主导模式.卧龙保护区对当地社区的影响主要是:提高当地知名度、发展旅游业提高收入、限制资源的利用等;当地社区对卧龙保护区的影响主要是:协助保护野生动植物、参加联防工作、放牧破坏生物生境等.影响卧龙保护区与当地社区之间关系的主要因素是:政策、旅游和社区活动.建议建立专职的社区共管部门,聘请当地居民参与生态旅游,并设立野生动物破坏补偿委员会.对卧龙保护区与当地社区关系的评价便于管理人员整体把握各项社区管理措施的管理成效,从关系模式的主要影响因素着手,提高保护区的社区管理水平.     

自然保护区生物标本资源共享子平台红外相机数据库建设进展

利用红外相机技术对安徽省鹞落坪国家级自然保护区大中型兽类及林下鸟类的调查

鹞落坪国家级自然保护区位于大别山脉南麓的核心地带。2014–2017年,作者采用红外相机技术对鹞落坪国家级自然保护区的大中型兽类及林下鸟类进行调查。研究共布设了72个相机位点,累计完成16,658个相机工作日,获得独立有效照片2,142张,共记录野生兽类9种、鸟类15种,隶属8目15科。包括国家一级重点保护野生动物1种,即安徽麝(Moschusanhuiensis),国家二级重点保护野生动物2种,分别是勺鸡(Pucrasiamacrolopha)和白冠长尾雉(Syrmaticusreevesii)。相对多度排名前五的兽类分别为小麂(Muntiacusreevesi)、野猪(Susscrofa)、赤腹松鼠(Callosciuruserythraeus)、猪獾(Arctonyxcollaris)和岩松鼠(Sciurotamiasdavidianus)。相对多度排名前五的鸟类为白冠长尾雉、勺鸡、松鸦(Garrulus glandarius)、灰背鸫(Turdus hortulorum)、红嘴蓝鹊(Urocissa erythroryncha)。此外红外相机还拍摄到大量人类活动照片,表明当地人类活动较为严重,应加强管理。本研究初步了解了保护区内大中型兽类和林下鸟类群落信息及人类活动的干扰情况,为保护区未来的保护和管理工作提供了数据基础。     

Human demography and reserve size predict wildlife extinction in West Africa.

Species-area models have become the primary tool used to predict baseline extinction rates for species in isolated habitats, and have influenced conservation and land-use planning worldwide. In particular, these models have been used to predict extinction rates following the loss or fragmentation of natural habitats in the absence of direct human influence on species persistence. Thus, where direct human influences, such as hunting, put added pressure on species in remnant habitat patches, we should expect to observe extinction rates higher than those predicted by simple species-area models. Here, we show that extinction rates for 41 species of large mammals in six nature reserves in West Africa are 14-307 times higher than those predicted by models based on reserve size alone. Human population and reserve size accounted for 98% of the observed variation in extinction rates between reserves. Extinction occurred at higher rates than predicted by species-area models for carnivores, primates and ungulates, and at the highest rates overall near reserve borders. Our results indicate that, where the harvest of wildlife is common, conservation plans should focus on increasing the size of reserves and reducing the rate of hunting.     

三江源国家公园长江源园区人熊冲突现状与牧民态度认知研究

大型哺乳动物肇事导致人类与野生动物之间的关系恶化,报复性猎杀严重威胁到野生动物的生存。三江源国家公园内人熊冲突问题严重,棕熊肇事不断突破了当地牧民的容忍度,严重影响其保护的积极性,了解人熊冲突现状和牧民态度认知对于制定和实施有效的防熊措施至关重要。通过分析2014年1月—2017年12月三江源国家公园长江源园区内上报的296起棕熊肇事案件,同时结合半结构式访谈法对71户牧民进行访谈,以期了解该地区人熊冲突现状和牧民对棕熊的态度认知。研究结果表明:(1)棕熊主要肇事类型为入侵房屋,同时也捕食少量牲畜,以绵羊和山羊为主;(2)每年6—8月为人熊冲突高发期,8—10月为案件上报高峰期;(3)年纪较小和经历过棕熊肇事的受访者对棕熊的态度更为消极;(4)多数受访者认为过去10年里棕熊种群数量有所增加,其主要原因是新枪支政策的执行;(5)大部分受访者在防熊措施选择偏好上较为保守,认为修筑水泥墙和找人看守是保护财产最有效的两种途径。建议地方政府完善当前野生动物肇事补偿制度,促进利益相关者参与人熊冲突管理过程;提升电围栏防控技术,选择合适地点建立棕熊补饲站;为了保护人身安全,允许牧民在一定范围内合法使用防熊喷雾;未来应加强牧民生产生活方式的改变与棕熊行为之间关系的研究。     

野生动物就地保护与其分布地经济发展的相容性

生态文明建设对野生动物资源保护提出了新的要求。在实践中,需要借鉴国内外研究成果和成功案例,并克服目前我国野生动物保护中存在的问题。综述了国内外相关文献,认为:目前世界上的野生动物就地保护方式主要是建立保护区和国家公园,在发挥保护作用同时,也给周边居民带来负面影响,从而制约了野生动物保护与当地社区经济的协调发展。传统的"命令-控制型"保护政策忽略了当地居民的生活需求,不利于形成居民积极的保护态度;居民的保护态度除了受来自野生动物造成的损害的影响,还和周边居民的年龄、受教育程度、经济收入等密切相关;为提高居民保护积极性,经济激励机制有着重要作用。目前,国内外保护工作中一般应用的经济激励措施主要包括直接经济补偿、生态旅游、现代狩猎、生态补偿等。     

Troublesome neighbours: Changing attitudes towards chimpanzees (Pan troglodytes) in a human-dominated landscape in Uganda

Long-term human–wildlife sympatry depends on the willingness and capacity of local people to coexist with wild animals. With human population growth and deforestation for agriculture, farmers increasingly live in proximity to wildlife, including large mammals of conservation concern. Understanding local perspectives and concerns regarding wildlife is essential for informing appropriate management strategies that reduce conflicts and promote sustainable coexistence. Social science approaches therefore have a critical role in integrated conservation programmes. We undertook an attitude survey to understand residents’ perspectives about sharing a landscape with chimpanzees (Pan troglodytes) in an unprotected forest–agriculture mosaic in Uganda. Interviews (n = 134) in 12 villages demonstrate residents’ ambivalence towards living alongside these protected yet potentially troublesome mammals. Chimpanzee behaviour is reported to have undergone recent changes. Residents claim apes increasingly enter villages for food, threaten people, and pose a particular threat to children's safety. Chimpanzee numbers are believed to have increased locally. Most interviewees fear chimpanzees, considering them dangerous. Crop losses to chimpanzees were widely reported. Farmers tolerate raiding of domestic fruits, but not cash-crops. Results demonstrate that attitudes towards wildlife are not fixed. Reported changes to chimpanzee behaviour are challenging villagers’ traditionally benign attitude towards them. Even so, residents acknowledge benefits to chimpanzees because they reportedly displace other crop-raiding wildlife which, unlike chimpanzees, damage important staple food crops. Survey findings are contextualised with respect to recent, major land-use changes in Uganda (clearance of unprotected forest for timber and agriculture) that have precipitated a sharp rise in farmer–chimpanzee interactions. We discuss the study's broader implications for protected mammal management and conflict mitigation in human-dominated landscapes, and ask whether it is appropriate to expect impoverished rural farmers to accommodate large-bodied mammals that pose a potential threat to their safety and livelihoods.     

People and wildlife: Conflicts arising around the Bia Conservation Area in Ghana

Human–wildlife conflicts have drastically increased around conservation areas in Africa over the last decades. Underlying causes are similar across regions and can most often be attributed to land-use changes and increasing human populations. However, wildlife species composition involved in conflicts can vary tremendously across sites. Conflict assessment often focuses on prominent species such as elephants or other large mammals, and information on smaller wildlife species involved in conflicts is often lacking. We conducted 100 interviews in 10 communities around the Bia Conservation Area (BCA), Ghana, to address the type and extent of damage as well as possible factors influencing the risk of crop-raids. We assessed wildlife presence and relative densities through indirect observations on transects and spoor-plots in the transition zone between BCA and agricultural land. Crop-raiding was present across all communities interviewed but was more than twice as high in the north compared to the south. Squirrels (Sciuridae spp.) were the most frequent crop-raiding species (92% of farmers experienced damage), but elephants (Loxodonta africana cyclotis [Matschie, 1900]) were nevertheless the major conflict generating species (84% of farmers experienced damage). Squirrel signs were 75 times as frequent as any other species recorded in the farmland. Cocoa (Theobroma cacao) was most frequently raided (99%), followed by cassava (Manihot esculenta) and yam (Dioscorea spp.). Raiding might have been promoted through inappropriate agricultural practices while only few current mitigation strategies have been successful so far. Promising strategies include chili fences and buffer zones, in which less susceptible crops such as chili pepper are planted. Further education of farmers on mitigation measures is needed, including training on improved farming practices.     

Road Development and the Geography of Hunting by an Amazonian Indigenous Group: Consequences for Wildlife Conservation

Protected areas are essential for conservation of wildlife populations. However, in the tropics there are two important factors that may interact to threaten this objective: 1) road development associated with large-scale resource extraction near or within protected areas; and 2) historical occupancy by traditional or indigenous groups that depend on wildlife for their survival. To manage wildlife populations in the tropics, it is critical to understand the effects of roads on the spatial extent of hunting and how wildlife is used. A geographical analysis can help us answer questions such as: How do roads affect spatial extent of hunting? How does market vicinity relate to local consumption and trade of bushmeat? How does vicinity to markets influence choice of game? A geographical analysis also can help evaluate the consequences of increased accessibility in landscapes that function as source-sink systems. We applied spatial analyses to evaluate the effects of increased landscape and market accessibility by road development on spatial extent of harvested areas and wildlife use by indigenous hunters. Our study was conducted in Yasuní Biosphere Reserve, Ecuador, which is impacted by road development for oil extraction, and inhabited by the Waorani indigenous group. Hunting activities were self-reported for 12–14 months and each kill was georeferenced. Presence of roads was associated with a two-fold increase of the extraction area. Rates of bushmeat extraction and trade were higher closer to markets than further away. Hunters located closer to markets concentrated their effort on large-bodied species. Our results clearly demonstrate that placing roads within protected areas can seriously reduce their capacity to sustain wildlife populations and potentially threaten livelihoods of indigenous groups who depend on these resources for their survival. Our results critically inform current policy debates regarding resource extraction and road building near or within protected areas.     

Assessment of Crop Damage by Protected Wild Mammalian Herbivores on the Western Boundary of Tadoba-Andhari Tiger Reserve (TATR), Central India

Crop raiding by wild herbivores close to an area of protected wildlife is a serious problem that can potentially undermine conservation efforts. Since there is orders of magnitude difference between farmers’ perception of damage and the compensation given by the government, an objective and realistic estimate of damage was found essential. We employed four different approaches to estimate the extent of and patterns in crop damage by wild herbivores along the western boundary of Tadoba-Andhari Tiger Reserve in the state of Maharashtra, central India. These approaches highlight different aspects of the problem but converge on an estimated damage of over 50% for the fields adjacent to the forest, gradually reducing in intensity with distance. We found that the visual damage assessment method currently employed by the government for paying compensation to farmers was uncorrelated to and grossly underestimated actual damage. The findings necessitate a radical rethinking of policies to assess, mitigate as well as compensate for crop damage caused by protected wildlife species.     

Diseases of humans and their domestic mammals: pathogen characteristics, host range and the risk of emergence

Pathogens that can be transmitted between different host species are of fundamental interest and importance from public health, conservation and economic perspectives, yet systematic quantification of these pathogens is lacking. Here, pathogen characteristics, host range and risk factors determining disease emergence were analysed by constructing a database of disease-causing pathogens of humans and domestic mammals. The database consisted of 1415 pathogens causing disease in humans, 616 in livestock and 374 in domestic carnivores. Multihost pathogens were very prevalent among human pathogens (61.6%) and even more so among domestic mammal pathogens (livestock 77.3%, carnivores 90.0%). Pathogens able to infect human, domestic and wildlife hosts contained a similar proportion of disease-causing pathogens for all three host groups. One hundred and ninety-six pathogens were associated with emerging diseases, 175 in humans, 29 in livestock and 12 in domestic carnivores. Across all these groups, helminths and fungi were relatively unlikely to emerge whereas viruses, particularly RNA viruses, were highly likely to emerge. The ability of a pathogen to infect multiple hosts, particularly hosts in other taxonomic orders or wildlife, were also risk factors for emergence in human and livestock pathogens. There is clearly a need to understand the dynamics of infectious diseases in complex multihost communities in order to mitigate disease threats to public health, livestock economies and wildlife.     

Reducing Wildlife Damage with Cost-Effective Management Programmes

Limiting the impact of wildlife damage in a cost effective manner requires an understanding of how control inputs change the occurrence of damage through their effect on animal density. Despite this, there are few studies linking wildlife management (control), with changes in animal abundance and prevailing levels of wildlife damage. We use the impact and management of wild pigs as a case study to demonstrate this linkage. Ground disturbance by wild pigs has become a conservation issue of global concern because of its potential effects on successional changes in vegetation structure and composition, habitat for other species, and functional soil properties. In this study, we used a 3-year pig control programme (ground hunting) undertaken in a temperate rainforest area of northern New Zealand to evaluate effects on pig abundance, and patterns and rates of ground disturbance and ground disturbance recovery and the cost effectiveness of differing control strategies. Control reduced pig densities by over a third of the estimated carrying capacity, but more than halved average prevailing ground disturbance. Rates of new ground disturbance accelerated with increasing pig density, while rates of ground disturbance recovery were not related to prevailing pig density. Stochastic simulation models based on the measured relationships between control, pig density and rate of ground disturbance and recovery indicated that control could reduce ground disturbance substantially. However, the rate at which prevailing ground disturbance was reduced diminished rapidly as more intense, and hence expensive, pig control regimes were simulated. The model produced in this study provides a framework that links conservation of indigenous ecological communities to control inputs through the reduction of wildlife damage and suggests that managers should consider carefully the marginal cost of higher investment in wildlife damage control, relative to its marginal conservation return.
