Assessing Local and Surrounding Threats to the Protected Area Network in a Biodiversity Hotspot: The Hengduan Mountains of Southwest China.

Protected areas (PAs) not only serve as refuges of biodiversity conservation but are also part of large ecosystems and are vulnerable to change caused by human activity from surrounding lands, especially in biodiversity hotspots. Assessing threats to PAs and surrounding areas is therefore a critical step in effective conservation planning. We apply a threat framework as a means of quantitatively assessing local and surrounding threats to different types of PAs with gradient buffers, and to main ecoregions in the Hengduan Mountain Hotspot of southwest China. Our findings show that national protected areas (NPAs) have lower and significantly lower threat values (p<0.05) than provincial protected areas (PPAs) and other protected areas (OPAs), respectively, which indicates that NPAs are lands with a lower threat level and higher levels of protection and management. PAs have clear edge effects, as the proportion of areas with low threat levels decline dramatically in the 5-kilometer buffers just outside the PAs. However, NPAs suffered greater declines (58.3%) than PPAs (34.8%) and OPAs (33.4%) in the 5-kilometer buffers. Moreover, a significant positive correlation was found between the size of PAs and the proportion of areas with low threat levels that they contained in both PAs and PA buffers (p<0.01). To control or mitigate current threats at the regional scale, PA managers often require quantitative information related to threat intensities and spatial distribution. The threat assessment in the Hengduan Mountain Hotspot will be useful to policy makers and managers in their efforts to establish effective plans and target-oriented management strategies.

The influence of differing protected area status and environmental factors on the macroinvertebrate fauna of temperate austral wetlands

One means of conserving wetlands is to designate the area around them as ‘protected’. Although many different types of protected areas exist, ranging from international (Ramsar-listed) to local importance, there is little information on how the type of protection influences biodiversity conservation. Studies of the effectiveness of protected area systems are a priority, if we are to understand their importance and design systems effectively. Many Tasmanian wetlands are regarded as having high to very high conservation values with more than 60% located within protected areas. This study tested macroinvertebrate richness and assemblage responses to a range of environmental attributes and differing types of protected area status at 66 protected Tasmanian (Australian) wetlands. Two hundred and eighteen taxa were identified with an average of 33 species (or morphospecies) and 18 families recorded per wetland. The wetland assemblages were idiosyncratic, four families contributed 21% of the total recorded and only two families contributed greater than 10%. Wetlands were not significantly nested on the basis of the composition of their macroinvertebrate assemblages. No single environmental attribute had a strong relationship with macroinvertebrate richness or assemblage composition and neither species richness nor assemblage composition varied significantly between different types of protected areas. Although the majority of protected area types were designed to support terrestrial conservation objectives rather than wetland values, our results suggest that the latter were also afforded protection. The state of the proximal zone (the terrestrial zone within 50m of the wetland edge) and the type of aquatic habitat present (macrophyte or sediment-dominated substrates) were the most important determinants of macroinvertebrate richness and assemblage composition across all types of protected wetlands. These results suggest that for temperate austral wetlands located within protected areas, the macroinvertebrate fauna will be best conserved by minimal disturbance of proximal lands.

Elephants over the Cliff: Explaining Wildlife Killings in Tanzania

Many incidents of elephant killings have recently taken place in Tanzania as well as in other African countries. Such events are usually presented as results of the rising global demand for ivory. As we show in this case study, however, not all violence against elephants is driven by the ivory trade. This article presents an event that occurred in West Kilimanjaro in 2009 when numerous villagers chased a herd of elephants over a cliff, killing six of them. Using a ‘web of relations’ approach, we seek to uncover the underlying as well as the immediate factors that led to this incident. A severe drought sparked off the event as elephants increasingly raided crops and destroyed water pipes. There are growing elephant and human populations in the area, which must be understood in the context of land use changes. Large areas have in various ways been turned into different types of protected areas during the last few decades as results of efforts by conservation NGOs and governmental agencies. In between these areas, people try to sustain a living on the remaining land, while encountering increased problems with wildlife. Conservation in the study area takes place without local communities having any real influence on decision-making. This leads to a feeling of being marginalized and disempowered, which again causes resistance to conservation, as in this case.

The Diverse Properties of Private Land Conservation in Chile: Growth and Barriers to Private Protected Areas in a Market-friendly Context

Private land conservation and many other contemporary environmental practices and policies are commonly described as 'market-based' or 'market-driven.' We argue that this characterisation derives in part from a conflation of private property rights with markets, and that it can obscure the diversity of institutional logics, practices, and political dynamics involved in conservation. We seek to illustrate this diversity through an analysis of private protected areas (PPA) in Chile. Through the experiences of different types of protected areas, as well as the related policy debates, we explore the ideological, political, and institutional conflicts and barriers to private land conservation within a legal and policy framework widely considered to be market friendly. Based on the diverse qualities of property rights observed in conservation projects we suggest the need for a critical environmental research agenda focussed on this neglected form of institutional diversity.

The value of a name: Estimating the economic impact of public land designation

Public land designations have been shown to have significant impact on their contextual regional economies. This paper reviews the existing literature on how public lands impact the proximate regional economies in which they are situated. Based on this collected wisdom the paper synthesizes past lessons into a comprehensive impact methodology. This methodology distinguishes quality effects in terms of visitors’ willingness to pay for sites of higher quality and quantity effects in terms of additional visitation to such sites to give a more comprehensive methodology for characterizing visitation and economic impact of protected area designation. We focus on National Monuments and National Parks, given that these two types of public lands have the broadest popular exposure and feature the most reliable data. A case study is then presented for a hypothetical protected area in Ferry County, Washington, USA, applying this new methodology to assess the likely economic effects of different types of protected areas.

Has the final countdown to wildlife extinction in Northern Central African Republic begun?

AbstractThe wildlife populations of Northern Central African Republic experienced precipitous declines during the 1970s and 1980s. While anecdotes coming out of the region indicate that the wildlife populations remain under serious threat, little is known about their status. An aerial sample count was carried out in the Northern Central African Republic at the end of the dry season in June 2005 and covered an 85,000 km2 complex landscape containing national parks, hunting reserves and community hunting areas. Results show a dramatic decline of wildlife since the previous survey in 1985. In 20 years, large mammals’ numbers decreased by 65%, probably because of poaching and diseases brought by illegal cattle transhumance. Elephant (Loxodonta africana) and Buffon kob (Kobus kob) populations showed the greatest decline (over 80% each), while buffalo (Syncerus caffer), roan antelope (Hippotragus equinus) and Giant Lord’s Derby Eland (Taurotragus derbianus) populations seem stable or increasing over these last 20 years. The analysis of the wildlife population distribution by status of the different types of protected areas (national parks, hunting areas) showed that individual encounter rates of elephant and buffalo were lower in national parks than in neighbouring hunting areas, while those for roan, giraffe (Giraffa camelopardalis) and Buffon kob were higher in the national parks.

Can engaging local people’s interests reduce forest degradation in Central Vietnam?

Governments in tropical countries are still responding to increasing forest degradation by implementing different types of protected areas. In general, due to their negative image as causes of deforestation, local communities are being excluded from any management role in these conservation areas. However, in Vietnam, since 1986 various incentives have been proposed for alternative conservation models. Our surveys used a multidisciplinary combination of methods to work with one Pahy ethnic minority around the degraded forests of the proposed Phong Dien Nature Reserve in Central Vietnam. From the results of these surveys we obtained clear indication that conservation can be enhanced if local priorities, perspectives and wishes are better identified and taken into account. The local communities identified the need for, at least, limited extractive activities in the protected area. They also frequently stressed their willingness to participate in the monitoring and control of the area, and in the selection of local species for reforestation programmes. Communities can and should be actively involved in building a shared understanding of what the forest provides, how it can be conserved and the benefits to be obtained. Conservation in Vietnam has much to gain from local participation. However, suitable safeguards and incentives need to be in place to insure sustainable use of the forest resources.

The Landscape Approach

251 One of the greatest challenges for Latin America and the Caribbean, the most biologically and culturally diverse region in the world, is to halt the loss of species caused by habitat destruction and land degradation. Up to now, setting aside protected natural areas is considered the most effective alternative to conserve biodiversity. Protected areas, however, are under increasing assault by agricultural, silvicultural and industrial development that surround and isolate them, reducing their habitat quality at the landscape scale. Among the different types of protected areas that have been proposed, biosphere reserves stand out for their attempt to compatibilize social development and conservation. Their management is the most amenable to integration of natural and human disturbance, inclusion of traditional management techniques, and participation by social and economic sectors in the administration. Biosphere reserves have proliferated all over the world, and today there are 531 of them located in 105 countries, where they protect vast ecological and cultural diversity. Even though the design of biosphere reserves is based on the landscape concept, it has yet to take into account ecosystem scales, possible long-term effects of disturbances, and better integrate and give higher consideration to the knowledge and experience of numerous ethnic groups that live within them. However, this requires a transformation of the function of the core, buffer and transition areas. The current design of biosphere reserves is centripetal because the main function of the buffer zone is to protect biodiversity in the core. We propose a centrifugal model, where biodiversity of the core spreads freely toward the area of greater human influence with the buffer zone functioning as a connector. This connectivity can promote land use practices that are in alignment with both ecosystems functioning and biodiversity conservation in natural, semi-natural, urban and industrial landscapes.

Residents’ attitudes toward three protected areas in southwestern Nepal

Understanding people’s beliefs and attitudes toward protected areas is a key factor in developing successful management plans to conserve those areas over the long-term. Yet, most of the emphasis in understanding people’s perceptions has been on the conflicts that exist between people and protected areas, such as loss of traditional extraction access or damage by wildlife to crops and livestock. This study addresses the need to explore people’s attitudes toward protected areas in a way that allows them to define and describe the values they hold toward the areas and the relevant issues and concepts. Three contrasting protected areas in the southwestern region of Nepal were chosen for this study to gain a broad representation of the values people hold toward different types of protected areas. Three themes emerged that describe the positive perceptions residents have: recreation/esthetics, environmental preservation, and economic benefits. Four themes emerged that describe the negative perceptions: negative economic impacts, belief that benefits are for the government or foreigners, fear of wildlife, and negative interactions with park guards. People’s perceptions are affected by different aspects of the areas, including the size of the area and people’s access to them, management objectives, history, and tourism. The diversity of these perceptions suggests that conservation strategies should recognize both positive and negative perceptions and work to foster and integrate diverse values in order to more accurately reflect the reality and complexity of people’s lives.

Rethinking protected area categories and the new paradigm

The World Conservation Union (IUCN) plays a global leadership role in defining different types of protected areas, and influencing how protected area systems develop and are managed. Following the 1992 World Parks Congress, a new system of categorizing protected areas was developed. New categories were introduced, including categories that allowed resource extraction. Since that time there has been rapid growth in the global numbers and size of protected areas, with most growth being shown in the new categories. Further-more, the IUCN has heralded a ‘new paradigm’ of protected areas, which became the main focus of the 2003 World Parks Congress. The paradigm focuses on benefits to local people to alleviate poverty, re-engineering protected areas professionals, and an emphasis on the interaction between humans and nature through a focus on the new IUCN protected area categories.The purpose of this paper is to examine critically the implications of the new categories and paradigm shift in light of the main purpose of protected areas, to protect wild biodiversity. Wild biodiversity will not be well served by adoption of this new paradigm, which will devalue conservation biology, undermine the creation of more strictly protected reserves, inflate the amount of area in reserves and place people at the centre of the protected area agenda at the expense of wild biodiversity. Only IUCN categories I–IV should be recognized as protected areas. The new categories, namely culturally modified landscapes (V) and managed resource areas (VI), should be reclassified as sustainable development areas. To do so would better serve both the protection of wild biodiversity and those seeking to meet human needs on humanized landscapes where sustainable development is practised.
