自然保护区生态旅游对野生动物的影响

目前中国的很多自然保护区开展了生态旅游,但这类活动对野生动物的影响研究却十分薄弱,因此十分有必要在介绍欧美、澳洲学者的研究进展基础上,针对我国的研究现状,提出该领域的研究方向、监测和管理策略.自然保护区的生态旅游活动主要有野生动物观赏、徒步行走、摄影、野外宿营、山地车或雪地车、电动或机动艇游湖、溪涧漂流、环境教育、社区访问等,旅游活动类型、范围、强度、时空分布等是影响对野生动物干扰大小的主要因素.生态旅游对野生动物的影响包括直接影响(个体的行为反应和生理指标改变、繁殖力降低、种群分布和物种组成的改变等)和间接影响(生境破坏、外来种散布和环境污染等).国外生态旅游对鸟类的影响研究较多,主要集中鸟类的惊飞反应、取食、能量消耗、繁殖等方面;对兽类影响的研究主要集中在行为、生理指标改变、种群数量等方面.我国未来的研究应注重收集基础性研究数据和深入探讨一些理论与应用问题,要运用多种技术手段对自然保护区野生动物的行为、生理、种群动态、物种多样性、生境质量、游客的时空分布、态度和行为等进行长期监测,而后将其结果应用到野生动物、生境以及游客的管理决策中去.另外,研究中应重视自然科学和社会科学的多学科交叉融合.     

Critical evaluation of a long-term, locally-based wildlife monitoring program in West Africa

Effective monitoring programs are required to understand and mitigate biodiversity declines, particularly in tropical ecosystems where conservation conflicts are severe yet ecological data are scarce. “Locally-based” monitoring has been advanced as an approach to improve biodiversity monitoring in developing countries, but the accuracy of data from many such programs has not been adequately assessed. I evaluated a long-term, patrol-based wildlife monitoring system in Mole National Park, Ghana, through comparison with camera trapping and an assessment of sampling error. I found that patrol observations underrepresented the park’s mammal community, recording only two-thirds as many species as camera traps over a common sampling period (2006–2008). Agreement between methods was reasonable for larger, diurnal and social species (e.g., larger ungulates and primates), but camera traps were more effective at detecting smaller, solitary and nocturnal species (particularly carnivores). Data from patrols and cameras corresponded for some spatial patterns of management interest (e.g., community turnover, edge effect on abundance) but differed for others (e.g., richness, edge effect on diversity). Long-term patrol observations were influenced by uneven sampling effort and considerable variation in replicate counts. Despite potential benefits of locally-based monitoring, these results suggest that data from this and similar programs may be subject to biases that complicate interpretation of wildlife population and community dynamics. Careful attention to monitoring objectives, methodological design and robust analysis is required if locally-based approaches are to satisfy an aim of reliable biodiversity monitoring, and there is a need for greater international support in the creation and maintenance of local monitoring capacity.     

中国的野生动物红外相机监测需要统一的标准

采用及时、可靠的方法对物种开展有效监测是生物多样性保护的基础。红外相机技术可以获得兽类物种的影像、元数据和分布信息, 是监测生物多样性的有效途径。这项技术在野外便于部署, 规程易于标准化, 可提供野生动物凭证标本(影像)以及物种拍摄位置、拍摄日期与时间、拍摄细节(相机型号等)等附属信息。这些特性使得我们可以积累数以百万计的影像资料和野生动物监测数据。在中国, 红外相机技术已得到广泛应用, 众多机构正在使用红外相机采集并存储野生动物影像以及相关联的元数据。目前, 亟需对红外相机元数据结构进行标准化, 以促进不同机构之间以及与外部保护团体之间的数据共享。迄今全球已建立有数个国际数据共享平台, 例如Wildlife Insights, 但他们离不开与中国的合作, 以有效追踪全球可持续发展的进程。达成这样的合作需要3个基础: 共同的数据标准、数据共享协议和数据禁用政策。我们倡议, 中国保护领域的政府主管部门、机构团体一起合作, 共同制定在国内单位之间以及与国际机构之间共享监测数据的政策、机制与途径。     

植被、海拔、人为干扰对大中型野生动物分布的影响——以九寨沟自然保护区为例

利用九寨沟自然保护区内8条动物监测样线在2003—2010年的生态监测数据,分析了植被、海拔、人为干扰对大中型野生动物分布的影响,结果显示:1)本监测共记录到保护区内大中型野生动物26种,其中兽类18种,鸟类8种,属于我国Ⅰ级、Ⅱ级保护动物的分别有5种和11种。2)针阔混交林和针叶林是大中型野生动物种类最丰富的两种植被类型(分别有26种和17种),阔叶林和灌丛次之(分别为10种和12种),草地最少(2种)。3)海拔2400 m以下的地方,大中型野生动物种类稀少,为10种,2400—2599 m海拔段物种数增加至20种,之后随海拔上升物种丰富度下降。4)人为干扰显著影响大中型野生动物的空间分布:历史上的人类活动将原生森林植被转化为次生的落叶阔叶林、灌丛和草地,使树正、亚纳和尖盘等地下坡位(相对海拔0—199 m)的大中型野生动物的物种丰富度降低(分别为4、2、2种)。包括旅游活动和交通在内的人为干扰,可能导致附近50m海拔范围内保护动物的缺失,并使下坡位的某些物种向高海拔处移动。生境破碎化则使野生动物的种类组成发生改变,使原有森林内部优势种,如羚牛(Budorcas taxicolor),逐渐被适应能力强的物种,如豹猫(Prionailurus bengalensis)、雉鸡(Phasianuscolchicus)和野猪(Sus scrofa)等所取代,并将长期影响野生动物种群的存活。当前九寨沟自然保护区大中型野生动物的分布是植被、海拔与人为干扰综合作用的结果。     

保护地旅游公路的野生动物通道设计原则与技术参数

保护地以其丰富的生物多样性和优美的自然环境为生态旅游的开展提供了基础条件。近年来, 保护地的生态旅游与旅游道路建设得到了飞速发展。旅游公路的修建, 在促进经济发展的同时, 也带来了野生动物致死、基因隔离、栖息地丧失、生境破碎化等一系列生态问题。因此设立合适的野生动物通道作为一种有效方式, 成为缓解公路对野生动物负面影响的主要途径。本文基于动物通道相关研究, 提出通道设计应遵从针对性、科学性、持续有效性、可行性四条原则, 道路生态学与保护生物学相关理论、保护地管理法规与管理规划、关键物种或类群生态学特性与栖息地现状以及沿线地形地貌特征都应作为通道设置的参考依据; 并从通道建设的数量、位置、类型、尺寸、表面设计、配套设施以及后期监测等方面提出了通道建设的技术参数。为长期有效地发挥野生动物通道的生态功能, 建议制定通道建设技术规范, 细化通道技术参数, 积极开展科研监测, 以缓解道路对野生动物的影响。     

International Society for Wildlife Endocrinology: the future of endocrine measures for reproductive science, animal welfare and conservation biology

Hormone analysis is a precise and widely accepted tool for monitoring reproductive function and responses to stressors. Although hormones are present and can be measured in various biological matrices, non-invasive methods have gained popularity over the past 30 years as a more practical approach for assessing ovarian, testicular and, more recently, adrenocortical activity in intractable wildlife species. Non-invasive hormone monitoring also has been key to understanding biological mechanisms related to observed behaviours of captive and free-ranging animals. Despite the increasing popularity of this research field, wildlife endocrinologists have not had a specific forum for sharing and discussing their latest findings, technical developments and common challenges. To provide such a communication platform, the International Society for Wildlife Endocrinology (ISWE) was established in 2010, followed by an international meeting held on 3-4 November 2011 at the Toronto Zoo, Canada. Over several sessions, keynote speakers and participants discussed recent developments of new and innovative methods for hormone monitoring, as well as the latest advances in basic endocrinology as applied to adrenal function, reproductive physiology, animal health, ecology and evolution. Here, we introduce ISWE to the scientific community and discuss how this new society will serve as a resource for wildlife endocrinologists worldwide.     

Towards harmonious conservation relationships: A framework for understanding protected area staff-local community relationships in developing countries

This paper conceptualises a framework for assessing protected area (PA)–community relationships and is premised on the view that positive PA–community relationships enhance conservation. A meta-synthesis of existing academic literature with a qualitative orientation was used to review the PA staff-community relationships, and data were analysed using an inductive qualitative approach. From a review of 105 published documents focusing on wildlife conservation, community involvement and PA–community relationships, it emerged that relationships are mostly influenced by attitudes. With the case of PA–community relationships, the question that arises is ‘whose attitude’? The paper proposes that both PA staff attitudes and community attitudes play an important role in shaping these relationships. Based on these findings, we propose a PA–community relationship framework that illuminates the human–wildlife interface as critical space in shaping conservation attitudes. In particular, four major factors affecting PA staff-community relationships were identified: (i) history of creation of the PAs focusing on forced relocation, and the fences and fines approach; (ii) benefits and costs associated with living closer to PAs; (iii) socio-demographic factors in which the influences of sex, age, level of education, number of years stayed in the village, experience accrued from working in PAs, household size, number of livestock, sources of income, and level of income; and (iv) community involvement in conservation-related developmental projects. We conclude that enhanced PA–community relationships promote wildlife conservation through participatory approaches and collaboration between PA staff and communities. We recommend for continued assessment and monitoring of PA staff and community relationships in order to allow for sustainable conservation especially in developing countries.     

The Event Book System: A Community-based Natural Resource Monitoring System from Namibia

Namibia's Community Based Natural Resource Management program is a joint venture between government, national non-governmental organisations and rural communities. A component of the program involves communities in monitoring various aspects of their conservancy, ranging from wildlife numbers, through economic returns, to patrolling records and infringements of the rules. A main feature of community monitoring is the Event Book System, which differs from conventional monitoring in that the community dictates what needs to be monitored, and scientists only facilitate the design process and conservancy members undertake all data analysis. The system has been adopted with good results by more than 30 communal conservancies in Namibia, covering almost seven million ha, and is now also being piloted in six national parks. Continued emphasis is needed on enhancing community interpretation and use of data for active adaptive management, particularly where conservancy leaders are transient due to the democratic nature of local organizations. Moreover, because the system is driven by local priorities, it does not cover all aspects of a comprehensive biodiversity monitoring programme. Where society deems other biodiversity values worth monitoring, conservancies must either be willingly persuaded to act on this, or external systems must be established to cater for these needs. If a community already has a monitoring system of its own, a win–win solution might be for the community to be sub-contracted to undertake these ȁ8external modules' on behalf of national agencies.     

Hunter Self-monitoring by the Isoseño-Guaraní in the Bolivian Chaco

Declared in 1995, the 34,400 km² Kaa-Iya del Gran Chaco National Park is the first protected area in South America co-managed by an indigenous organization, the Capitanía del Alto y Bajo Isoso (CABI). In 1997, based on historical occupation by the Isoseño-Guaraní over the past 300 years, CABI formally demanded a 19,000 km² `Tierra Comunitaria de Orígen' (TCO) that adjoins, but does not overlap, the national park. The creation of TCOs and the co-administration of protected areas are elements of decentralization processes in Bolivia, whereby the management of land and natural resources is devolving to departmental and municipal levels of government. This paper examines biodiversity monitoring in the context of a community wildlife management program developed with CABI. Hunter self-monitoring (100–150 hunters per month) combined with monthly activity records for potential hunters (7637 observed hunter-months) permit estimations of total offtakes of subsistence game species for 1996–2003, as well as catch-per-unit-effort over the same time period. These data show considerable fluctuations from year to year and no declining trends that would suggest over-hunting. Monitoring populations of multiple game species can be relatively expensive, even with the voluntary support of hunters, considering data collection and analysis, as well as presentation and discussion through community meetings. At the same time, monitoring does not provide highly accurate assessments of short-term changes in wildlife resources. However, relatively simple participatory methods are important for generating information on long-term trends and for creating a context for community discussion of formal wildlife management.     

犬瘟热与野生动物

犬瘟热是一种犬瘟热病毒引起的多种动物共患传染病,在世界范围内的家犬和野生动物中多次爆发。犬瘟热的跨种间传播对多种野生动物如东北虎、非洲狮、雪豹、大熊猫等野生动物的种群安全造成严重威胁,并且感染的宿主范围仍在扩大。近年来的研究表明,犬瘟热病毒的不断变异和野生动物栖息地内流浪犬只的增多使我国野生动物尤其是野外种群正在面临犬瘟热的严重威胁。为了更好地应对犬瘟热对野生动物的危害,本文综述了犬瘟热的病原特征和在野生动物中的流行病学、致病机制、诊断与治疗以及疫苗免疫方面的研究进展,在此基础上提出了针对传染源、传播途径、易感动物三方面的控制措施来减少野生动物犬瘟热的传播风险。目前,由于国内自然保护区科研技术力量欠缺以及防控意识薄弱,对于野生动物犬瘟热的监测处于空白状态,这无疑加大了野生动物犬瘟热的防控难度。因此,为了保障我国野生动物种群安全,我们需要加强在野生动物犬瘟热监测与流行病学方面的研究工作,建立有效的监测防控体系将犬瘟热阻挡在野生动物种群之外。     

Design and Implementation of Monitoring Studies to Evaluate the Success of Ecological Restoration on Wildlife

Restoration projects are often developed with little consideration for understanding their effects on wildlife. We contend, however, that monitoring treatment effects on wildlife should be an integral component of the design and execution of any management activity, including restoration. Thus, we provide a conceptual framework for the design and implementation of monitoring studies to understand the effects of restoration on wildlife. Our underlying premise is that effective monitoring hinges on an appropriate study design for unbiased and precise estimates of the response variables. We advocate using measures of population dynamics for response variables given that they provide the most direct measures of wildlife status and trends. The species to be monitored should be those constituting an assemblage of umbrella species that represent the range of spatial and functional requirements of wildlife in a restored ecological system. Selection of umbrella species should be based on strong empirical evidence that justifies their usage. We also advocate that monitoring be designed as true experiments or quasi‐experiments rather than as observational studies to allow for stronger inferences regarding the effects of restoration on wildlife. Our primary message is that if monitoring is to be done, it must be scientifically based.     

Fostering Community-Based Wildlife Health Monitoring and Research in the Canadian North

Many northern Canadians have continued a subsistence lifestyle of wildlife harvesting and, therefore, value sustainable wildlife populations. At a regional wildlife workshop in the Sahtu Settlement Area, Northwest Territories in 2002, elders and community leaders raised concerns regarding wildlife health, food safety, and the effects of climate change on wildlife. They requested that efforts be put toward training youth in science and increasing involvement of hunters and youth in wildlife research. In response, we initiated a long-term, integrated approach to foster community-based wildlife health monitoring and research. Annual trips were made to all schools in the Sahtu from 2003 to 2009 to provide hands-on learning for 250–460 students on a range of wildlife topics. In addition, interviews were conducted with 31 hunters and elders to document their local ecological knowledge of wildlife health and local hunters were trained as monitors to collect tissue samples and measurements to assess body condition and monitor health of harvested caribou (n = 69) and moose (n = 19). In 2007 the program was extended to include participation in the annual caribou hunt held by one community. Each year since 2005, a graduate student and/or a postdoctoral trainee in the veterinary or biological sciences has participated in the program. The program has evolved during the last 6 years in response to community and school input, results of empirical research, hunter feedback, local knowledge, and logistical constraints. The continuity of the program is attributed to the energetic collaboration among diverse partners and a unified approach that responds to identified needs.     

Investigating the feasibility of a passive tracking index for monitoring wildlife in the Lower Omo Valley, Ethiopia

In many places in Africa, constraints in human, financial and physical resources are common problems that limit the effectiveness of wildlife researchers and managers. In an attempt to identify a useful tool for monitoring African wildlife populations, we tested a passive tracking index (PTI) methodology on a unique wildlife resource area in the Lower Omo Valley, Ethiopia. The methodology had previously proved valuable for monitoring a wide variety of wildlife species, including ungulates and carnivores in North America and Australia. Two ungulates (lesser kudu and dikdik), a carnivore (hyaena), a primate (baboon), and a ground foraging bird (guineafowl) were simultaneously indexed. In addition, single observations were recorded for genet, serval and caracal. The species indexed also represent the broad needs for monitoring wildlife. The mammal species are of economic importance to the region through sport hunting. Two of the species, hyaenas and baboons, potentially conflict with human agricultural interests through depredations on livestock and crop production. Anthrax periodically decimates the wildlife in the Lower Omo Valley, Ethiopia, but losses of many species are difficult to observe or quantitatively document. The PTI is a simple‐to‐apply, easy‐to‐calculate means to quantify simultaneously population trends for multiple species, and particularly applicable to sustainable harvest by sport hunting, human–wildlife conflicts, and impacts and recovery from wildlife disease.     

Combining citizen science and recreational hunters to monitor exotic ungulates and native wildlife in a protected area of northeastern Argentina

Monitoring wildlife population trends is essential for resource management and invasive species control, but monitoring data are hard to acquire. Citizen science projects may monitor species occurrence patterns in time and space in a cost-effective way. A systematic management program of exotic wild boar (Sus scrofa) and axis deer (Axis axis) in a protected area of northeastern Argentina (El Palmar National Park) provided a framework for implementing a wildlife monitoring system based on park-affiliated hunters. We assessed the level of agreement between three indices of relative abundance: hunter sightings and camera trapping for wild boar, axis deer, capybaras (Hydrochoerus hydrochaeris), brown brocket deer (Mazama guazoubira), and crab-eating and pampas foxes combined (Cerdocyon thous and (Lycalopex gymnocercus), and catch per unit effort (CPUE) for both exotic ungulates only. Most (74%) hunting parties participated in the monitoring program and contributed to its sustainability. Bland-Altman plots displayed large levels of agreement between methods across species, with larger systematic differences between sighting and camera-trapping indices for native species. Restricting camera-trapping to the same time window as hunter sightings substantially increased the agreement between methods across species. Sighting and CPUE indices revealed similar temporal trends and large variations in spatial patterns between species. Comparison of the number of sighted and killed exotic ungulates indicated that, on average, 17% of wild boar and 75% of axis deer escaped hunters. The three indices were appropriate metrics for management purposes and corroborated the sustained, high-level abundance of axis deer and low numbers of wild boar in recent years.

     

探讨我国森林野生动物红外相机监测规范

Reconciling Wildlife Management's Conflicted Purpose With a Land Community Worldview

ABSTRACT To reach its potential wildlife management needs a coherent purpose. Traditional divisions between science, society, and nature, however, create conflicts between responsibility to science, the public, and nature. These divisions emerged as early as Plato's (400 BC) allegory of the cave. In Plato's allegory human society existed inside a cave formed by its own delusions, and a philosopher or scientist could leave the cave and apprehend reality in nature. Wildlife management's simultaneous responsibility to public preferences, objective truth, and biotic integrity provides the foundation for a conservation worldview capable of transcending the divisions embodied in Plato's allegory. In this paper we deconstruct the conflicted worldview standing on that foundation and describe a land community-based worldview for wildlife management that could replace it. The transition from traditional views of science, society, and nature to a land community worldview requires 1) changing scientific stewardship from seeking objective truth to seeking credible truth, 2) changing political stewardship from following societal dictates to representing wildlife within the land community, and 3) changing ethical stewardship from protecting biotic integrity to fighting permanent closure of land community boundaries. Adopting a land community worldview for wildlife management requires relinquishing the illusion of absolute objectivity and a fall from status as neutral arbiters of knowledge but provides a means for honorably seeking reliable knowledge, serving the public and respecting the land community.     

Comparing data of different survey methods for sustainable wildlife management in hunting areas: the case of Tarangire–Manyara ecosystem,northern Tanzania

Cost–benefit considerations of wildlife monitoring are essential, particularly, in areas outside national park boundaries, where resources for conducting wildlife censuses are scarce, but that, at the same time, are subject to high pressure for wildlife utilization, such as hunting. Large mammal survey data from various sources were collated and analyzed to investigate which methods are best suited for monitoring purposes at low cost in the Tarangire–Manyara ecosystem, northern Tanzania. Our results indicate that primary data (from aerial and road transects counts) that involve direct species observations, although sometimes very expensive, are required for establishing the status of the target species in terms of density or population size. Concomitantly, secondary data from various sources, such as interviews, hunting quota, and damage reports, obtained over wide areas and over longer periods of time, can provide important information on presence/absence and distribution of species within an area. In addition, the study revealed that hunting quotas set did not correlate with species abundance/numbers from the primary data surveys for most of the large mammals hunted within the ecosystem. For a better conservation and management of wildlife, in particular with respect to the forthcoming formation of Wildlife Management Areas, we propose an integrated approach to wildlife monitoring using primary and secondary data sources through the involvement of local people’s knowledge.
