Environmental scientists and managers increasingly recognize that socio-cultural evaluations expand the understanding of human–nature relationships. Here, user groups’ perceptions of the benefits from and threats to nature were analysed in Tierra del Fuego National Park, Argentina. We hypothesized that the different relationships of users to this place would lead to significantly different valuations among local Ushuaia residents (n = 122), Argentine nationals (n = 147) and international tourists (n = 294). All users perceived a broad spectrum of benefits. The three groups assessed intrinsic and relational values more highly than instrumental benefits, and significant differences included a higher mean valuation of benefits by Argentine visitors. Overall, threats were less perceived than benefits, and significant differences included a higher mean threat assessment by Ushuaia residents. To explain these relationships, we found that mean valuations of benefits and threats were weakly related to increased biodiversity knowledge for residents and international tourists, but not for Argentine visitors. These findings can orient environmental management in Patagonia and elsewhere by identifying areas where information can improve user experiences and by contributing a more pluralistic understanding of nature from multiple stakeholders.

Recent studies have highlighted that illegal activities occurring within protected areas, including the poaching of fauna and flora, cannot be addressed with increased law enforcement alone. Moreover, research on the increasingly militarized nature of front-line conservation efforts has pointed to potentially detrimental aspects of such approaches. This has led to a shift in focus to identifying ways to further engage local communities in the prevention and reduction of wildlife crimes. However, few studies have examined the potential for changing the responsibilities of front-line conservation personnel or their views on such changes. Such insight is vital in forecasting the successful adoption of, or possible resistance towards, a more community-oriented policy. We examined rangers’ perceptions in Uganda to assess their attitudes towards traditional enforcement strategies and alternative, non-enforcement approaches for reducing illegal activities in protected areas. Our findings suggest that although respondents believed that traditional enforcement strategies (e.g. foot patrols) are important and effective in reducing wildlife crime, these strategies on their own were insufficient to address illegal activities. Study participants emphasized the importance of expanding the role of front-line rangers, in line with approaches suggested in the policing literature. We discuss the implications of our findings for transdisciplinary conservation science research and front-line conservation policy and practice.

Protected areas are central to global efforts to prevent species extinctions, with many countries investing heavily in their establishment. Yet the designation of protected areas alone can only abate certain threats to biodiversity. Targeted management within protected areas is often required to achieve fully effective conservation within their boundaries. It remains unclear what combination of protected area designation and management is needed to remove the suite of processes that imperil species. Here, using Australia as a case study, we use a dataset on the pressures facing threatened species to determine the role of protected areas and management in conserving imperilled species. We found that protected areas that are not resourced for threat management could remove one or more threats to 1,185 (76%) species and all threats to very few (n = 51, 3%) species. In contrast, a protected area network that is adequately resourced to manage threatening processes within their boundary could remove one or more threats to almost all species (n = 1,551; c. 100%) and all threats to almost half (n = 740, 48%). However, 815 (52%) species face one or more threats that require coordinated conservation actions that protected areas alone could not remove. This research shows that investing in the continued expansion of Australia's protected area network without providing adequate funding for threat management within and beyond the existing protected area network will benefit few threatened species. These findings highlight that as the international community expands the global protected area network in accordance with the 2020 Strategic Plan for Biodiversity, a greater emphasis on the effectiveness of threat management is needed.

Reliable information on wildlife populations and the threats they face is crucial for assessing the performance of conservation strategies. As part of its efforts to improve the effectiveness of Bukit Barisan Selatan National Park in Sumatra, Indonesia, and aid the recovery of flagship species, the Park's management authority designated a 1,000 km2 forest block an Intensive Protection Zone. To set a baseline from which to evaluate the performance of this zone, we investigated the density of tigers Panthera tigris sumatrae, and spatio-temporal interactions between tigers, their principle prey and threats. The estimated density of tigers was 2.8 per 100 km2, whereas in 2002 camera-trapping failed to record any tigers in the Intensive Protection Zone. We found the study area contained a rich prey base, with muntjac deer Muntiacus muntjak, macaques Macaca nemestrina and wild pigs Sus scrofa occupying 85–98% of the area, and sambar Rusa unicolor 61%. Despite these promising findings we also recorded a relatively high number of people entering the Park illegally, with 77 incidents over 6 months, of which 20% involved armed poachers. The poachers operated mainly at night and were concentrated in two locations. Law enforcement patrol teams were active during the day, and therefore had little overlap with the poachers. Prioritizing these at-risk areas for increased protection by rangers would further secure the Intensive Protection Zone, and expanding ranger activity across the Park would support efforts to remove the Park from UNESCO's List of World Heritage In Danger.

Examining the human dimensions of conservation science continues to generate attention, with a move towards an interdisciplinary agenda that incorporates both the natural and social sciences, and recognition of the importance of understanding human involvement in biodiversity and ecological matters. However, one line of enquiry has been largely neglected: the job perceptions of front-line conservation area rangers. Examining intrinsic and extrinsic motivational factors can shed light on job stress and job satisfaction, recruitment, productivity, and retention and turnover. Furthermore, little is known about potential intergenerational linkages within the ranger profession, which is a significant gap, given the potential role of the family in pre-employment socialization and career choice. Drawing from surveys of 530 rangers working in 39 conservation areas in 11 Asian countries, we found variation amongst intrinsically motivated, extrinsically motivated, and mixed-motivated rangers in terms of a desire to see their children become rangers. Extrinsically motivated rangers were most likely to want their children to enter the profession, and intrinsically motivated rangers expressed significant concern about the inadequacy of the work environment. Implications for both conservation and criminal justice policy and research are discussed.

To achieve their conservation goals individuals, communities and organizations need to acquire a diversity of skills, knowledge and information (i.e. capacity). Despite current efforts to build and maintain appropriate levels of conservation capacity, it has been recognized that there will need to be a significant scaling-up of these activities in sub-Saharan Africa. This is because of the rapid increase in the number and extent of environmental problems in the region. We present a range of socio-economic contexts relevant to four key areas of African conservation capacity building: protected area management, community engagement, effective leadership, and professional e-learning. Under these core themes, 39 specific recommendations are presented. These were derived from multi-stakeholder workshop discussions at an international conference held in Nairobi, Kenya, in 2015. At the meeting 185 delegates (practitioners, scientists, community groups and government agencies) represented 105 organizations from 24 African nations and eight non-African nations. The 39 recommendations constituted six broad types of suggested action: (1) the development of new methods, (2) the provision of capacity building resources (e.g. information or data), (3) the communication of ideas or examples of successful initiatives, (4) the implementation of new research or gap analyses, (5) the establishment of new structures within and between organizations, and (6) the development of new partnerships. A number of cross-cutting issues also emerged from the discussions: the need for a greater sense of urgency in developing capacity building activities; the need to develop novel capacity building methodologies; and the need to move away from one-size-fits-all approaches.

Tigers Panthera tigris are highly threatened and continue to decline across their entire range. Actions to restore and conserve populations need to be based on science but, in South-east Asia, information on ecology and behaviour of tigers is lacking. This study reports the relationship between the home range size of female tigers and prey abundance, using data from radio-collared tigers in Huai Kha Khaeng Wildlife Sanctuary, Thailand, and published data from other studies. A total of 11 tigers, four males and seven females, were fitted with global positioning system collars, to estimate home ranges using 95 and 100% minimum convex polygons (MCP). Prey abundance was estimated by faecal accumulation rates. The mean home range size of male tigers was 267 and 294 km2 based on 95 and 100% MCPs, respectively; the mean female home range size was 70 and 84 km2, respectively. Territories of male and female tigers had little overlap, which indicated both sexes were territorial. Mean densities of the prey species sambar Rusa unicolor, barking deer Muntiacus muntjac and large bovids were 7.5, 3.5 and 3.0 km−2, respectively. When female home range size and prey abundance were compared at six locations in Thailand, and at other sites in India, Nepal, Bangladesh and Russia, a significant negative correlation was found between prey abundance and home range size. Monitoring this relationship can provide managers with metrics for setting conservation goals.

Annual revenue flow to developing countries for ecotourism could be as large as US$ 29 billion, providing an enormous financial incentive against habitat loss and exploitation. However, surprisingly little quantitative evidence exists on the profitability of the rainforest ecotourism sector, which determines the incentive and capacity of the sector to engage in conservation. A Peruvian rainforest ecotourism cluster generated US$ 11.6 million in 2005. The after-tax profit margin was at least 14% and has increased with tourist volume. High profitability, coupled with new legislation, has allowed operators to put 54 358 ha of rainforest near the new Interoceánica Sur highway under private management and to engage in conservation actions. A previously published microeconomic contract model of protected-areas management identifies two key features of rainforest tourism that link ecotourism to conservation: (1) tourists demand an immersive experience, which incentivizes the acquisition of large amounts of forest cover, and (2) institutional reforms have increased the expected effectiveness of conservation actions. In Peru, these conditions appear to be met, so that profits from ecotourism can combine with new land tenure rights to create a governance structure within which the industry can act as an independently financed partner to the conservation community.

In the Cardamom Ranges (Cambodia) community-based natural resource management (CBNRM) is proposed by the international non-governmental organizations (NGOs) community as a natural resource management strategy to achieve the targeted outcomes associated with the protected area (PA) management plan. Local people are expected to participate in CBNRM projects such as community forestry (CF) in order that the protected area management plan can be realized. The experiences of the local people are juxtaposed against the aims of these local biodiversity projects. Overall, it is accepted by the NGOs and government agencies that communities need to be involved in the design and management of the PA and that the protection of biodiversity resources can only occur with the provision of alternatives for local livelihood options to decrease land clearing for agriculture and harvesting of wild foods and animals. This case points to a basic misalignment between biodiversity conservation and CBNRM. Participants in this study contested the meaning and usefulness of the PA and the CF projects. Their concerns were cultural, social, economic and political, exposing uneven relations of power and uncertainty associated with the long term outcomes. Participation itself required scrutiny in this situation, as did the promotion of a global biodiversity ‘good’ over local understandings of place and landscape. Lessons from more than 20 years of participatory CBNRM may be used to reconfigure the CBNRM ideal, to assist planners and implementers towards an integrated approach with biodiversity values reflected in both conservation and local production systems, acknowledging that these systems are culturally constituted.

Edge effects arising from road construction and other development in protected areas can negatively affect the behaviour of wildlife, particularly large carnivores. The Asiatic leopard Panthera pardus is a large carnivore that may be sensitive to edge effects. Camera trapping was used to assess the influence of human disturbance along forest edges on leopard behaviour and habitat use in a 104 km2 area of Kaeng Krachan National Park, Thailand. A minimum of four male and two female leopards was recorded in the study area. A Park access road bisecting the study area was not a barrier to leopard movement but movements and activity were affected by human traffic inside the Park. A regression model showed that leopard habitat use increased with distance from human settlements at the forest edge. As in other parts of its range, leopards at Kaeng Krachan National Park tended to show less diurnal activity in areas more heavily used by people compared to areas less used. As is the case with tigers, such responses may pose a threat to leopard population persistence but more research is needed to determine the demographic implications of edge effects for Asiatic leopards and other large tropical carnivores, and the appropriate mitigation strategies required.

The modern era of wildlife and protected area conservation in Nepal began in 1973 with the passage of comprehensive legislation, and has evolved very quickly as new priorities and problems have emerged. Here we explore the legal and managerial development of conservation areas, a recently-defined category of protected area designed to promote conservation through local-level participation and development. A review of the Conservation Area Management Regulations of 1996 shows that there are several potential problems inherent in this designation. As written, the regulations move power from the government to organizations under governmental contract. Thus, management authority largely remains top-down from the standpoint of local users. We also question how well the designation will protect some sensitive wildlife species, since organizations do not have law enforcement authority under Nepalese legislation.

Despite these concerns, there have been several successful conservation area programmes in existence in Nepal since the 1980s and most of the issues addressed are surmountable with the current regulations, providing that several criteria are met. We propose that His Majesty's Government and organizations under contract develop more definitive methods of disbursing funds for local-level projects, and institute social impact assessments. In addition, more attention must be paid to wildlife law enforcement; independent assessments of important wild populations and unique habitats are needed. Finally, we discuss some broader issues that should be better addressed in Nepal and elsewhere, including cross-sectoral coordination within the government.
